Any information or program you choose to put into use from this video is done AT YOUR OWN RISK. As a precaution, I recommend backing up any irrecoverable data before practicing any of the methods shown in this video.
This is the advanced troubleshooting technique video tutorial of how to possibly fix a PC that will that will not beep when booting the system; that will not display anything on screen, and that will essentially not progress into and past POST.
This video will try to troubleshoot and resolve this situation: although your fans may spin up, your PC will never properly boot and never progress past this stage. You cannot access or interact with your computer, and are otherwise stuck. Furthermore, the ON/OFF power button doesn't power down machine unless you hold the power button for a number of seconds. It is as if your PC is stuck in idle, sleep or hibernation mode.
This video will show you first and foremost how to clear the CMOS which will hopefully allow you to then access your BIOS.
Furthermore, if you find yourself in the situation where your computer powers on for a mere second or a couple of seconds, and then immediately powers off and will not power back on again (essentially the power feed to your PC does not remain stable) this can often be attributed to a short circuit. Skip ahead (fast forward) to 15:20 to find out how to solve this issue.
This video will also show you how to breadboard a PC, allowing you to test components on your motherboard that is outside of the case before even having to mount the hardware within the case. Skip ahead (fast forward) to 20:20 to find out how.

If you find yourself in this situation (a PC that will turn on but will not beep and will not display anything on screen), try to Do what my video shows: disconnect the power cable, remove the CMOS battery, short the CMOS jumper pins for 9 seconds then return the jumper cap to its initial position (only if you can find these jumper pins; if not, skip this step), press your PC's chassis power button switch (to discharge any remaining power circulating in the system), leave the PC unplugged and in this state overnight, then the next day return the CMOS battery to its socket, power up the PC, and if no beep, then disconnect the power cable, press your PC's chassis power button switch (to discharge any remaining power circulating in the system), remove one component, power up the PC, and if no beep then repeat (each time unplugging the PC, pressing the power switch to discharge remaining power, removing a remaining component, and then powering up, and this until the PC beeps at boot).If it never beeps, even when you are down to just motherboard, power supply & CPU+fan, one of these remaining components may be bad

If your computer powers on but for a mere second or two and then immediately powers down, It sounds like your motherboard is developing a short circuit due to contact with the metal casing. Most likely it has to do with the screws and metal mounting stands (supports) that your motherboard sits on. The cheapest way to fix this problem is to introduce cardboard washers between the screws and where they make contact to the motherboard, or you can buy plastic mounting supports at a computer shop.
Alternatively, to ensure that it is in fact the computer developing a short circuit due to contact with the metal casing, you can always Breadboard it: Skip ahead (fast forward) to 20:20 to find out how.

AWARD MODULAR BIOS POST BEEP ERROR MESSAGE CODES:
One beep when displaying logo - no error during POST
Long beeps in an endless loop - no system RAM installed or detected
One long beep followed by three short beeps - video card not found or video card memory bad
High-frequency beeps when the system is working - the CPU is overheating and the system is running at a lower frequency
---
Beep error codes differ from one BIOS manufacturer to the next. To discover what the beep error code is trying to telling you, discover the manufacturer of your BIOS (available in the motherboard's manual or on the motherboard's manufacturer's website {on the page for your specific motherboard model}) and then look up the frequency and interval of your beep error code on:

Heh, thanks for the kind words. Sadly no OBD2 type scanner exists for PC motherboards. Given that said scanner would need to access the computer in order to diagnose what's wrong (and in these cases the computer is not accessible by any means) the scanner wouldn't be able to read any error codes (or anything for that matter). Computer technicians generally perform electric resistance checks and swap-out tests to speed this process along (the average PC owner probably does not have another MB : )
This happened to me and I had no bleeps. All I did was disconnect the power to a hard drive, I didn't even touch the sata cable. But when I switched back on it started up but with no bleep. I asked Tom's Hardware but I got no reply. I felt lost, but then I found this video. Superb! Thanks for posting.
+nivekvb My pleasure. Happy to help : )
Nicely done, Rodney. I was just about to give up on my ASUS M2N68 AM PLUS. I followed your CMOS instructions and she fired right up. My original problem was no display. Everything else worked.
+TheCircuitman1 Excellent! Enjoy the PC : )
It worked ty but I have now Another problem with it want to do startup repair over & over
Greetings mate. I just wanted to thank you for all your insights and help methods with the external parts of the pc. In truth not only did it help me save my pc but also thought me alot about a pc. Thank you for the video
+francois du preez Nice! Very glad to be of help : )
Thank you! My computer is still acting up, but resetting the CMOS gave me visual. I'm not good at the hardware, but give me software and I have a chance. Thanks for the really clear tutorial.
+Mateo Rothbauer My pleasure. Hope things improve with time.
Probably the most helpful breadboarding vid. Was having issues and thanks to u found out it was my RAM
+Jesus Ruan Very glad I could help : )
for testing power supplies you can get a tester at Fry's for $13, saves you a lot of trouble.
I always test the power supply first with my tester then I know it's ok.
Thanks for the tip.
Aliexpress has 'em for $6 and change free shipping but you have to wait for two weeks to get it from The Land of Manufacturing.
Heh, well said : )
Thank you for the whole tutorial and especially about the CMOS reset guide! I really needed that.
Nice! Glad to be of help : )
Axle69e Chances are your repair partition is corrupt and cannot be used to repair the PC any longer. What I recommend you do is using a different PC with a cd burner, download and burn a Linux Live CD which you will then use to boot your defective PC with. There, you can back up any irrecoverable files to USB mass storage (such as a removable hard disk or a USB flash key). Once that is done, you will have to boot up the machine with your desired operating system's install disc (Windows I presume), and will then have to format your machine and reinstall from scratch. It's unfortunate but if you have exhausted every recovery option on that repeating recovery screen without results, then I do not know what else to tell you. You may want to google search 'windows recovery repeats' and see if anyone else has a better solution. Good luck with it.
Excellent work!!
Thanks for taking the time and explaining clearly.
Hope you make many more of such videos.
+Wickrama Wimalasiri My pleasure. Thank you for the kind words : )
@jake emery Good diagnosis! Glad you got to the bottom of the issue : )
Fantastic Rodney! I like what you taught me about the stand offs.
Cool! Hope the info can help : )
Thanks man. I found out it was my RAM sticks, they had been blown from a power surge. Tried these old DDr3's that i had laying around and i finally got to the BIOS :] cheers man
+moqi x My pleasure. Glad things are up n running again : )
Thanks for the Video. I was going to look for a trouble shooting manual to help me diagnose my three year old Gatway that stopped running. I removed or disconnected everything that I could see that was disconnectable (bad word) from the motherboard and still get no beep. I'm waiting for a PS tester to arrive in the mail. I may do the breadboard isolation of the motherboard, after I check the Power Supply. Many thanks, again, Dude!
I hope things worked out
Hello.i'm chea suktin,i live in Cambodia,thank you so much,Mr Jake Emery,i wish you good luck too bye.
I'm having this same issue, and have followed all these steps and in the first video as well. I have narrowed down the problem to either a faulty motherboard or a faulty CPU, both of which are brand new. I am not getting an error beeps. How can I test to figure which of these 2 components is the problem, without having a 2nd device for testing them individually? Thanks!
+KrizmKazm Firstly, thank you for properly doing the research beforehand, I appreciate that. Secondly, sadly without double parts to do swap tests, I haven't a clue on how to test beyond this. Sorry I couldn't be of more help : \
+RodneyDickson no problem. That post was actually a year old and I've sinced rebuilt a whole new system. It turned out to be a faulty (brand new) motherboard. I don't have much luck with buying new electronics. I always seem to get something faulty, even when buying brand new hardware. I got a new system from CyberPowerPC.com and it's amazing.
+KrizmKazm Right on then. Enjoy the machine : )
Is it possible to short out a new board if I installed it but forgot to put the fan sink clamp metal x thing on the back of the board?it turns on and fans spin at maximum but nothing else happens
mate, thank you so so much, this video has saved me buying a knew gaming pc and made my day! im happy I came across some one like you on TH-cam today..... thank you again. =D
+Calton Xavier My pleasure! Thanks for the kind words and happy gaming : )
thanks for your video which helped me to clear my cmos which fixed my motherboard thanks a lot!!!
You bet! Glad the information could help : )
Thank you mr. Rodney Dickson.
+Hemanth Kumar Pappu My pleasure. Hope everything worked out : )
On my cpu, It has no beep at all but the fan is working but theres no beep.. what do you think is the possible solution ?
have you tried to watch this video? ...at all?
Should you not test that the CMOS button battery is not dead?
Mine was - I hadn't used my tower for several months ('had a new laptop to play with) and the battery was a year or two old. I replaced it with a new one but it still didn't POST (power on self-test) and beep. Yet all mobo LED lights light as normal.
I think I'll need to try clearing the CMOS BIOS, etc. as you suggest.
BTW - I terminally blew my previous mobo by replacing the CMOS clearing jumper on the wrong pins, D'oh - so use your glasses and plenty of light to make sure you know the original position of the jumper!
Thanks for your help with these vids.
Good tip regarding the CMOS CLR jumper. Regarding the testing of the CMOS battery, well, normally I would say that 'what does it matter, if the PC ends up posting, you will discover upon your next power outage (or the next time you move the PC) whether or not your CMOS battery needs replacing or not'. Unfortunately, through the feedback I've received from others, it seems that some motherboards actually REQUIRE a functional CMOS battery just to operate, which I feel is ludicrous (but alas, I don't manufacture motherboards, so I guess all I can do is complain openly about this : \
Jake Emery Well, this can cause issues, yes, but I doubt you did permanent damage to the board just by omitting this item. What you COULD have done however, is not provided sufficient cooling to your CPU and hence caused permanent damage to that. Nonetheless, try the steps in the video and see if they revive the PC. Good luck.
sir i have the same problem but it only happens when the video card is connected to psu but when i unplug the connector from the psu to the video card its boot up i plug the monitor to the onboard card instead.
definitelyji
Hmm, sounds like it could be a number of different culprits. Has this video card ever worked properly on the motherboard you are testing it on before?
yes it worked before, it started when i played nba 2k14, then it shut off like the cpu was unplugged..the graphic card fan is spinning though when it attach to the motherboard, it only wont boot up when i plug the 6 pin connector from the psu to the graphic card... please bare with my poor english
definitelyji
Hmm, may be damage to either the motherboard or video card. Try what is shown in this video (regarding the resetting of the CMOS) and see if that solves anything. Lemme know how it turns out.
Dear Rodney if I turn my computer on,my computer power on,fan is spinning ...only black screen and no beep,after I take out my RAM I got 1 beep and 2 short beeps,but if I put back my RAM no display and no beep again,it beeps only when I take out the RAM....so what should I do next?Will you please help me?
+Alex Lalhmunsanga Did some research on your beep problem, and it is indicating that there is a video card output issue, not RAM. HOWEVER, given that there are no beep error codes when the RAM is connected, I would try first either unplugging the PC and reorganizing the order of RAM modules in the sockets then powering up, OR try unplugging the PC and trying different amounts of RAM modules or different RAM modules altogether before powering up. If none of these work, try a different video output device.
Thank you. well explained most techniques.
Thanks for the kind words : )
I am just going to leave a comment here, because I found this useful, but; I am doing a motherboard swap after having years of I/O probs and USB probs with an MSI. I bought a Asus board because they are my favorite, and really struggled to get it to boot.
I wasn't getting any fans or anything. I put it back to the MSI board and still couldn't get it to boot and somehow the power switch was bad, out of all of that.
So I found a junk emachines power switch and made the msi work (different i/0 plug in) and ordered a new power switch, to which I tried to install it all today, and no fans or post.
That is what I found this, and you give be the idea, though I had already done it, to basically remove everything except the main 24 and start from ground up.
Turns out, it was that the 4 pin cpu power was in wrong. The PSU came with two of them, and one fit at a left hand snap way, and found out the other one fit at a verticle top side clip angle and I guess that was it.
So I am loading windows on it now with everything hooked up and am not out of the woods yet but that was a huge hurdle for me.
I like your video, seems to be the best I ran across for the no post issue, given that no fans spin, rather than what most of them are, which is fans and just no video which is most likely for them a video card or driver issue. But this covers that too.
Thanks.
Thanks for sharing your story : )
what if everything disconnected but cpu and power while bread boarding and the psu turns off 3 seconds after power up and the psu itself gives 2 beeps and does this in a loop.

Hey there, just wanted to share that if you want to turn off the computer using the power switch, you have to hold it down for a few seconds.
Yep, some PCs will respond to this, some will not, but thanks for the tip.
The problem is your MB if you have already verified the PS is ok. Most likely bad caps. i would either throw the board out and get a new one or use a visual check of the caps, look for any burn marks or bulges and finally USE an ESR meter to verify bad caps. Replace and try the board again.
For other readers, the use of the term 'caps' in this post refers to capacitors (those small cylindrical items all over your motherboard).
Good tip valveman12, thanks for sharing : )
RodneyDickson I just went through the same troubleshooting on a MB. I used my ESR meter to check all the caps but there are all good. So next I'll look at any regulators. Failing that, I would have to assume a control chip has blown. MB can be frustrating.
valveman12
Heh, you're far more knowledgeable in the subject than I am. After trying everything in this video, if I did not spot any physical damage to the board (such as bulging capacitors or burn marks on contacts) I would simply give up on it. Hope you can find a way to bring the board back : )
RodneyDickson Well MBs are tricky. i will work on a MB until it no longer becomes economically feasible. i.e. a similar MB goes on sale :O)
valveman12
Sounds like a good course of action to me : )
My issue was my ram, it was DDR 2 but at 558 MHz but the board supports DDR 2 atb667 or 800
Hi thank you for this very informative video. But then I would like to ask if I can do it in another way I mean, I will start by removing everything from the main board and then one by one re install the components/boards until the problem will emerge because I understand you are doing this while boards/components are on board and removing them 1 by 1. Which do you think is more preferable? Thank you very much
The reason behind removing components one at a time is because generally the end user wants to get their PC up and running as quickly as possible with as little effort as possible. However, removing everything from the motherboard and testing through building is perfectly acceptable as well, however doing so will require more effort to return all of the removed components from the board afterwards : ) Just ensure that your board has a CPU, heatsink+fan, PC motherboard speaker , power switch (generally from the computer case) and power supply connected to it and from there ensure you are hearing beep error codes upon every boot (until both RAM and some sort of video out is established of course) and from there you should ensure that each boot produces a POST beep message and a POST screen. Good luck with the build : )
My computers been working for 2+ years, but one day it decided to shut down by itself and turns off after a couple seconds. I tried to see what the problem is and found out when I install all 4 RAM sticks in the computer, it will turn off within the first 5 seconds of booting. But when I keep 2 RAM sticks the computer stays on no problem but will not display anything. I just can't figure out what the problem is here. Help please.
The problem sounds directly related to a short circuit created by contact with the metal casing (sometimes, builds can 'tough' through the short circuits until one day they can no longer). If you've reset the CMOS (unplugged the PC and removed the button cell battery for an hour or so) with no luck, then I highly recommend you breadboard your PC to confirm if this is the issue. Skip ahead (fast forward) this video to 20:20 to find out how.
I did everything on the video . but when I remove both ram it makes 1 long beep during boot . I installed the ram back again and it still gives no beep or display during boot. help ?
Has this RAM ever functioned in this PC before or is this the first time you're trying it in this PC?
So here's my issue, I recently got some led fans, they came with these 2 pin connectors that were separate for the LEDs, without them it's just a normal fan.
I mistakingly plugged these into where my power sw and reset pins are on my mobo.
So now, the computer will not only not turn on, but it won't even post, the mobos LEDs and the led for my CPU cooler will come on briefly then turn off. It will do this repeatedly, and ironically it's with a specific PSU.
Idk what to do but I fear I bricked my board
+watsyurdeal Eek. Sadly this sounds like the case. You could try all of the steps in this video, but I wouldn't be surprised if it is dead for good. Good luck
ok i checked 6-pin power cable to the graphics card from the PSU. its hooked up i tried an another graphics card a while back why would my case's standoffs cause a short i have had this computer for years why would it just happen now ty for the help Reggie Wallace and RodneyDickson
Components sadly die off with time and use, it's common : \
Good day sir! I have the same problem, but what i did is i disconnected two of my fans on the system unit case (except the motherboard, video card and PSU fan); fortunately, my computer was able to beep, boot and reach the desktop, and i was able to use my computer normally. What i am worried of... is that my computer now lacks ventilation (due to fan disconnection, these fans are now like decorations hanging on the system unit case). What could the problem be? what should i do so that i can return these fans back to their uses?
Sorry for the late reply. I'd assume that the issue is related to a short circuit created by these fans when connected to the motherboard. Now I assume that you are using the fan connector type that connects directly to the motherboard in order to provide the needed power feed to these fans. What you can try to do, is first unscrew the metal mounting screws that bind the fans to the case, and replace these with plastic mounting solutions (I myself use cable ties - also known as zip ties or tie wraps - it doesn't look pretty, but it does the job.) If this doesn't work out, you can purchase power adapters that convert an IDE power connector to a fan connector (both ends female) which may alleviate the issue (since you are bypassing the motherboard connection completely). If none of these solutions work, try but one fan at a time to see which functions and stick with that one. If after all this, you cannot get the chassis fans to function, I'd replace the fans (chassis fans are not terribly expensive and can be purchased on eBay for cheap). Good luck with it.
I believe the CMOS Did the trick! Thanks bro you try and call customer service and there all confused but you helped alot thanks!
Nice! Glad I could help : )
I have a PC that is only giving me a single post beep. I have swapped the ram, power supply, Video card, and ssd. Getting no video output. I see all the lights light up and it go through it's checks but never get past that stage. No bios.
Ok, well, the single post beep is a good sign. Can you hear your hard drive spinning and loading the data from your operating system? I would guess it's an issue with the video output. I'd A) try a different PC on your screen to ensure the screen is functioning as intended, then B) try every video output you have available on your PC to see if perhaps the incorrect video output device is set in the BIOS. Good luck.
I have an ASUS M4A88T-M, after update from Microsoft computer stop working. It does graphics beep code. It there a way to by pass this. I clear the CMOS with no results. Any suggestions?
+gsuslives4ever That's bizarre! Hmm, if you did clear the CMOS overnight (with no power cable connected to the PC and the power chassis button pressed to discharge remaining power before the overnight wait) then perhaps your video adapter has become damaged? Not entirely sure. The way Windows 10 takes control of a PC's boot process, it's a whole new world to what I know. Sorry I couldn't be of more help : \
this is my issue...thanks will look at this video
Wishing you luck with it. Lemme know how it turned out.
Hi. At 25:30, May I know what is PC Speaker and its function.?
+Sanjay Prasad This speaker outputs the beep error codes, as well as the POST beep (when the system passes power-on self checks during a successful boot). It seems redundant should there be no problem, but can be very useful should your PC not be able to boot and instead reports a problem.
+RodneyDickson
Thanks for the reply. Don't we have in-built speaker which gives beep sounds. Why and in which cases we need this.?
+Sanjay Prasad Many PC manufacturers no longer include said PC speaker. If you have a connector for SPEAKER or SPK coming from your case, then there is one in the case. If you see one integrated on your motherboard, then you have one there. If not, you can always buy one of these at a computer shop. Should the PC not boot and not POST (as shown in the video) hearing the beep error codes can help greatly in diagnosing the problem at hand
+RodneyDickson
Understood. Thank you. :)
Informative video and for that I'm greatful, but you can belabor a point at a professional level.
Sadly I do not know that much. This is the best I can do I'm afraid.
I followed this and many other tutorials and the pc doesn't post. I'm suspecting that bios is corrupted or something. Any suggestions?
If you've tried everything in this video, including breadboarding the board, then yeah, you sadly might be outta luck with this one. The culprit will most likely be the board or the CPU (with other components still being viable to be used in another machine). If you see any burn marks or any bloated/burst capacitors on the motherboard, then it is to blame. Sadly, I can't think of any other suggestions: sorry I couldn't be of more help : \
Thanks for the videos, using this pretty much confirmed it was my mobo went bad. Now to see if they'll replace my mobo despite me breaking a pcie clip and the cpu bracket holder screw off...
Hope you got your replacement.
Hiya, I've got an old pc that I tried to connect to my hdtv through vga to vga but the display won't work.. it just goes blank (black screen) then power light flashes on the hdtv. Haven't used it in a while, for like 4 years lol but I recall it working... it powers up but but no beeps :( From what I've gathered, it could be the cpu or mobo... only using a keyboard, could a mouse not plugged in stop an old pc from booting up?
+Bored Gamer Doubt it. Sadly what you're describing is a confused BIOS that won't post (this is rather common for a PC that was left unused for a long time). If you want to resurrect that PC, you might want to follow the instructions in my video sadly. Good luck
Hi Rodney,
I am down to two components in determining the faulty one: CPU and Mobo. I went through your video and did all the steps but PC still no booting up. The fans run for 1-2 seconds and shut down. It was working fine yesterday and what I did (which I think somehow cause the issue) is I drilled a couple of holes to mount an extra fan in the case (PC shut down and unplugged); and after that the PC would not post. Was it the minor vibration that happened while drilling the holes?
Anyway, what I am trying to see is if there is a way to determine or make an educated guess as to which component it is - the CPU or Mobo?
I got Dell Studio XPS that is 4 years old but still runs decently ( or ran ... lol).
Hmm, if you actually breadboarded the mobo (as shown in the video) and the problem still persists, then I'd assume that metal shavings from the drilling actually contaminated the motherboard's contact points and is causing short circuits. If you haven't yet performed the breadboarding technique, I highly recommend it at this point. Lemme know how it turns out.
RodneyDickson I need help!! I have a custom built PC that was bought from someone so I did not build it myself. I've had it over a year w/no problems. A couple of weeks ago my computer shut off unexpectedly and would not turn back on. I figured out the problem was my PSU burned out. I replaced that. Now my computer turns on and beeps once, but nothing displays. I know that the monitors are working because they work on a different computer. Any suggestions?
+barbiethug04 Do you hear Windows bootup sounds?
Thank you it was amazingly helpful for me today! Saved my time and money! And best of all I am feeling self very expert :D
Nice! Glad I could help : )
good day sir. I currently have the same issue and I'm currently trying to fix it. I tried to follow your instructions but when I had the CMOS battery removed, it doesn't power up anymore. Your thoughts about it?
+Mark Jaycob Casera Some machines behave this way sadly. Try unplugging the PC, removing the CMOS battery, pressing the power chassis switch to discharge remaining power, leaving the PC as so overnight, and then in the morning reconnecting it all and see if the issue has resolved itself.
So what exactly was the problem with that PC?
Short answer: the motherboard in this video is simply put: junk. Long answer: a corruption of the CMOS settings was preventing the motherboard from properly entering POST with both video card and RAM modules connected. Removing the video card allowed the BIOS to write updated (and more proper) CMOS settings which then allowed both the RAM modules as well as the video card slot to be accessed.
RodneyDickson Thanks for your response.
I followed the same procedure as you did in the video, but my PC still isn't beeping/booting. So I guess the motherboard is dead. The thing is before I had the problem, my PSU would make sparking sounds when I plug in the power cord and one of my front USB ports use to give me notifications of a power surge whenever I plug in any usb device.
MarHutchy
Hmm, yeah, that definitely doesn't sound salvageable sadly. Although I cannot say confidently that the CPU is salvageable, chances are the rest of the components used in the PC are, so at least you can save a bit of cash on your next PC build by reusing some of the old components. Good luck with it : )
Thanks :)
I'm going for a 64-bit system this time.
MarHutchy
I myself now use a 64 Bit system for gaming and do have to say that it works great with a 64 Bit operating system. Best of luck with it all : )
hi Rodney it was my mb .ive fitted another one today but still have a problem. .it all boots up fine but when i try to connect my 2nd drive 1tb it will not boot up at all .could this be faulty drive .Thanks
It could be. It could also be a faulty SATA cable, faulty SATA port on the motherboard, faulty SATA power lead from the power supply, or a faulty power supply altogether. And you say that another SATA drive functions as intended?
Okay. So I wanted to build a PC and I did. It started out a bit rough, where the PC would only turn on for a few seconds and turn off and keep doing so until you unplug it. I somehow got it working and have worked. I hadn't touched it for a few months and I tried to turn it on. It then turned on for a spilt second. So, throughout the process I have swapped Power Supplies and both had the same outcome. I ordered a new motherboard. When I hooked up the new mobo, it now turns on for 5 seconds, and off and in a cycle until I unplug it. I am not sure why... I don't seem to be getting video signal either. I have replaced everything except the CPU and still nothing. I am going to get a new CPU. Would that fix it? Thanks so much!

I have had it out of case and minimum config. still no luck!!
If your computer powers on but for a mere second or two and then immediately powers down, It sounds like your computer is developing a short circuit due to contact with the metal casing. Most likely it has to do with the screws and metal mounting stands (supports) that your motherboard sits on. The cheapest way to fix this problem is to introduce cardboard washers between the screws and where they make contact to the motherboard, or you can buy plastic mounting supports at a computer shop (be forewarned though, these plastic mounting stands can not be reused after installation).
Alternatively, to ensure that it is in fact the computer developing a short circuit due to contact with the metal casing, you can always Breadboard it: 1)place the motherboard with CPU+Fan on wood or non-shiny cardboard 2)connect all of the case connectors to the board's panel 3)with a power bar that is OFF connect the PC power cable from the power bar to the power supply and the power supply to the board 4)while NEVER touching any exposed component,power on the power bar and press the power switch on the case.If the problem still persists,one of the remaining components is probably defective.Power off the power bar before dismantling
sir, my problem is my comp. not turn on ,but my power supply and switch button is ok. the first reason is no display, but now when i was turn on again didnt not work on ,no fun run and no LED light for the switch after i can clean a motherboard with small paint brush to remove the dust . what is the problem for my pc motherboard and how to fixed . this is a dead motherboard?? can you help me for this?? sorry for my wrong english. thanks
+KARLO TIZON Could be a multitude of issues, such as a short circuit or a weak power supply. The only way to test with such a broad issue is to breadboard the machine as shown in this video
Awesome videos even if you can't help me your a great teacher!! I only get any beeps when I removed all ram sticks. When I put each stick in one by one changing ram slots as well I get no beeps again. Can all three ram sticks be bad? Pc was built by me and it about a month old. I will try all your methods but I found it weird that only beeps I get it when all RAM is removed?

+BIG_ TIKKET It is possible that the RAM is simply not compatible with your board. I generally recommend that one buys the lowest speed RAM that they can for their board to ensure compatibility. Your motherboard's support website will let you know what RAM is compatible with your board.
+RodneyDickson thanks for your support. Ended up being the processor though. Keep up the good work!👍🏻
+BIG_ TIKKET Thanks for the update
Hi Rodney, I am having this same problem with my gaming pc. Tried all the steps up until breadboarding my motherboard but was not able to get any post error code beeps.
I will note this all came about when I was changing my ram into different slots I then booted up my computer and it instantly shut off with a slight burning smell from the PSU. I also checked the ram and one of the sticks was not seated correctly
After this the problems started can't get the pc to post or give any error beeps no matter what have even tried with a new PSU.
Might it still be worth breadboarding my setup and trying what you done towards end of video with inserting ram back in. Might this work or is it safe to say the motherboard is done for after ruling out the PSU?
+lee patton Here's the thing, I've once burnt out contacts on a RAM module, now, it is said that once that happens, shrapnel from said RAM module in the socket can cause a short and ultimately a mobo dying for good, BUT I am also cheap, so the way I handled it was to try to use a vacuum in the socket, but still boycotting the use of said RAM socket that had the burnout and instead relying on only the other RAM sockets. Keep in mind that your PC might die at any time, so keep that in mind and make backups often, but hey, if I were you, I'd run it into the ground (this, of course, if you could get it working through the methods shown in this video). Good luck with it all.
Been watching you're vids. thanks for the help/ I am building a pc for the first time in years. mostly new components. Ram, cpu,HardDrive are all frankinstiend: repurposed. build is complete and i am not getting any video. no beep codes and have pulled all components one by one with still not error code or beeps. I know it is possible to get a bad product even if it is new. what would you recommend now. posted the below to get any feedback to see if maybe something is not compatable with this 1150 socket build, thanks in advance

If this is new hardware that you are installing on your motherboard (that has not yet functioned on your motherboard), note that matching bus types of video card to motherboard socket (PCI-E for example), matching socket types of CPU to motherboard socket (LGA1366 for example) or matching bus types of RAM module to motherboard socket (DDR3 for example) does not necessarily signify compatibility. If this is the first time you are trying this hardware on your motherboard, there is a chance that this new hardware is not compatible with your motherboard, despite the same bus type and despite the fact that the new parts fit in their respective motherboard socket. Your motherboard manufacturer's website will have a support page dedicated to your motherboard's model, and on this support page should be a compatibility list for such components as video cards, CPUs and RAM modules. Ensure that your new component is certified to function with your motherboard, and if your new component is not present on the compatibility list, then there is a chance that the new component is not compatible with your motherboard.
Mines only turn on (no image) for a few seconds and then shut down after that i can't turn it on again only if i unplug the core
this can be attributed to a short circuit. Skip ahead (fast forward) to 15:20 to find out how to solve this issue.
Hey Rodney.....
Firstly an awesome job with the video mate....you have put in details to the last mile .....
i tried check each part....
when i removed the RAM and switched - i did nt the single or long beeps, which you get when you switch on the system without the ram or if there is a ram fault. - Is that sign of af aulty RAM ?
i checked the SMPS to, the fan seems to be running.
I don t have a graphics card - so i'd rule that out.
The HD seems to running - rule that out too
Did the memory reset option too..
What would you suggest i do next ?
Breadboard it: Skip ahead (fast forward) to 20:20 to find out how.
Hi there
i get 2 beeps and fans work for 1 second and then off again. light still on mothe
+anthony quinn Beep error codes differ from one BIOS manufacturer to the next. To discover what the beep error code is trying to telling you, discover the manufacturer of your BIOS (available in the motherboard's manual or on the motherboard's manufacturer's website {on the page for your specific motherboard model}) and then look up the frequency and interval of your beep error code on:
www.computerhope.com/beep.htm
One desktop here stopped working, would not power on at all, even the light.....a second desktop simply powers on with fans working but no beeping.......it's dvd drive initially failed to function beforehand.....so interesting to apply the video method to them.....at worst I could 'cannibalize' one to provide parts for the other....thanks for the instructions

Hey. I need help. My pc boot up but my monitor has no display. Mouse and keyboard ain't flashing. But the fan in my cpu is working. I dont know what to do. :(
Last thing i know. Is that i changed the ram settings in my computer. Can you help me?

If a try to open it said press f1 to continue but my ps2 keyboard not working . Same for usb keyboard all keyboard ill try is not work sorry for my bad english
+Maine Lasar Hmm, did you try a different PS/2 keyboard? Could be an issue with that specific keyboard.
In my PC, fan immediately start after give external voltage. and turn off it in 5 to 6 second. after press power batten of my PC , it not get any response . what i do..?
It sounds like your motherboard is developing a short circuit due to contact with the metal casing. Most likely it has to do with the screws and metal mounting stands (supports) that your motherboard sits on. The cheapest way to fix this problem is to introduce cardboard washers between the screws and where they make contact to the motherboard, or you can buy plastic mounting supports at a computer shop.
RodneyDickson thanks friend..
Akshay Adate
A pleasure. Happy to help : )
My computer did this to me yesterday, apart from the motherboard short circuited like a boss and now I need a new motherboard. I hate computers
Well, did you try breadboarding the board (as shown in the video)? Maybe the PC is still viable?
Hi video poster, I wanna show you my case, I own a Asus K45VM which I bought in 2013. I had to do some stuff like dual booting, which was working very well until the day I messed up my debian uninstalling every package and I need to reinstall that. I failed few times, I shouldve just formatted everything and Installed each OS again, but I really wanted only to format and reinstall debian, and keep windows 8 intact. So, at the end of the debian installation I was trying to install the grub, happened 2 months ago so I dont recall everything, but I had to reboot after that, and then it never came to live again. My symptoms are: no bios, no post, black screen, only the white power button led on, and the green energy led on. Fan spins for 1 second then stops, waits for 5 seconds then rises to full speed and stays like that forever. Im stuck I tried everything, removed everything but the graphic card and cpu. Is my mobo good for proper disposal? (GARBAGE).
PS: I will say your sentence everytime I need it, I just loved it!!!! "I believe this is........... good for garbage" hahahahha
+José Siqueira Heh, glad I've created a catch phrase for ya. Yeah, sadly if you've tried everything in this video, it sounds like your dual booting has rightly killed your PC sadly. Breadboarding (as shown in this video) may help in deciphering if anything is still salvageable. Good luck with it.
I need some help here, I have a ASUS M3A32-MVP Delx WifiAP board, Ram, CPU Video card all works, I have tried them out in different system, I have unhooked everything going to the board but power, I cant get the POST beeps back and no visual coming from board, If I put a new BIOS chip on the board would that help to solve the problem?
btw the HDD light on the case stays on.
Daniel Shively
Whoh, well this is a tricky situation: If you've tried EVERY component in a different machine and see no issue, then I'd assume that the issue lies in compatibility between the components you are assembling. Perhaps try what you see in this video and discover in which component the issue lies. Also, remember that despite your motherboard having the same bus type as your selected RAM and video card, note that the same bus type does not indicate compatibility. Your motherboard manufacturer's website will have compatibility lists to indicate which components are in fact compatible with your motherboard.
my computer has no disply but it has power what is the problem of my computer thanks
+kaekou213 Does it beep at boot?
Can you help me please? My computer starts beep we hear all the login sounds but the screen doesnt display somethink. We the screen to ckeck it and they siad its fine...
+Kostas HellCover Do you have multiple video output connections? Can you connect to a different output device?
+RodneyDickson its ok now.
+Kostas HellCover Good then
So I purchased everything I needed for a computer build and this happened to me. I have an ASRock fx 990 extreme 9 motherboard, and amd fx 4350 cpu, an ASUS Geforce gtx 750 ti video card, 8 gigabytes of ram, an old 200 gb hdd that I salvaged from an old desktop, a 400 watt power supply and an old monitor that was working with a different computer. Would there be any compatibility issues with these parts? Everything turns on and spins up but no beep and no display. The power supply was working with a different computer. A reply would be greatly appreciated! Thanks
Since this is new hardware that you are installing on your motherboard (that you have not yet got to work on your motherboard,) note that matching bus types of video card to motherboard socket (for example, both motherboard socket and graphic card are PCI-E 16X) or matching bus types of RAM module to motherboard socket (for example, both motherboard socket and RAM module are DDR3) does not necessarily signify compatibility. If this is the first time you are trying this hardware on your motherboard, there is a chance that this new hardware is not compatible with your motherboard, despite the same bus type and despite the fact that the new parts fit in their respective motherboard socket.

Ensure that your new component is certified to function with your motherboard, and if your new component is not present on the compatibility list, then there is a chance that the component is not compatible with your motherboard.
I finally fixed it lol it turned out i didnt have a vital power port plugged in... haha but i did have to buy a better power supply to get the right connector
+John Benfer Better that way! More power = more better : ) Good luck.
You mentioned that it could take anywhere between 10 seconds and 24 hours to clear the CMOS, depending on the computer. What would cause such a variation? Reason I'm asking is because I took the CMOS battery out of my HP laptop, waited 5 minutes and put the battery back in, with no effect.
Also, I'm wondering about the CMOS clear jump pins. Are those in all computers or just certain models? Do you have to go through the same process with laptops?
Thanks.
+madcapper6 A laptop is a tricky beast for this procedure. Make sure you unplug your PC and disconnect your PC's RECHARGEABLE battery (yes, the battery pack, not just the CMOS battery) as well as the CMOS battery, then press the power switch to discharge any remaining power. Wait overnight (since you tried the 10 minute variation, now try the overnight variation) and hope for the best. The variation has to do with the way PCs store reserve power (some discharge instantly, some require time to discharge reserve power). Finally, I have a similar video specifically for laptops: check it out if no luck th-cam.com/video/qRhphHjQrNk/w-d-xo.html
+RodneyDickson Thanks for the response. Much appreciated. Cheers
+madcapper6 You bet. Good luck.
Hi Rodney
i have a problem with my PC and i cant figure out what is exactly is damaged
i have removed all of the components but no beep code i even bought a new motherboard thinking that the old motherboard was damaged but the problem is still the same. here's my case
no beep codes, no display, i connected only the power supply and the CPU and the heatsink the PC fans works for about 45 sec and then it shut down for 4 sec and turn back
pls pls pls help me any idea on how to troubleshoot it

I agree with comment above
hey on my old pc when i tray to boot windows 7 i got black screen with only cursor on it and and it say your internal memory is corrupted that a ram problem ?
Sounds to be that, yeah. It would help to diagnose this if you had either A) spare RAM memory or B) a spare hard disk drive. I'd first try spare RAM memory and see if the problem persists, and if it does (or if you do not have spare RAM) try using a different HDD and reinstalling Windows 7 on that. If the problem does not persist, it could be that your original Windows 7 installation is simply corrupt.
BTW MemTest86+ is a great tool to test for memory (RAM) errors. It's open source freeware. You can get it at memtest.org
thanks for expert opinion i will do that
Still good stuff
I had no beep no boot problem on my desktop, after watching your video i found my motherboard has no speaker, and after taking everything a part ten times I made it work.
Problem was with ram, I had them on 1st and 3rd sockets, turns out it only works using 1st and 4th or just 1st.
Keep on with good stuff but try not to repeat yourself so much with useless stuff
In that case, glad I could help out : )

can you help me sir... i encounter a problem with my PC.... the problem is no post indicator or no beeps...
the history was when i played LAN games it works properly no sign of bad problem and its fine after i turn it off to go to bed.. then this today i turn on my pc and it fail to post .. :( no display on monitor...
Iv'ed done all the steps that i know...
1: i restart it for many times.. ( failed )
2: i remove all the inside parts like front panel USB, and others... ( failed)
3: i remove the cmos battery with in a minute then i re-insert it. ( failed)
4: i reset CMOS jumper. ( failed)
5: i switch the jumper 1 and 2 pin to place it in 2 and 3 pin. ( failed)
6: i start up the PC without cmos. ( failed )
7: when i remove the ram it response 1 long 2 short beeps... but when i re-insert the ram it didn't response :(... i try replacing it with borrowed ram but no post indicator.. i do it in 1st and 2nd ram slot ...
what should i do..? can you give suggestion sir :(?
I appreciate that you're trying many troubleshooting steps. If you have an addon video card as well as onboard, first ensure your PC is giving you the beep error code with the RAM removed, then unplug the PC, remove the addon video card, install the functioning RAM and try with onboard video. Also, you may want to try another video card (try borrowing one from someone) if the preceding doesn't work. Finally, if none of this works out, try breadboarding the PC as shown in the video (its the most complete way to eliminate variables that can cause this). Good luck with it.
MY new Pc is doing the turn on instant off. So, If its a short and the cause is not the supports what could it be?
Breadboarding this PC will reveal if the short is in fact caused by the case. If not, perhaps the power supply is not powerful enough or perhaps there is a defect in one of the components (I once had this issue with a video card that needed to be replaced). Hope this helps.
make sure the CPU is in properly.
RodneyDickson i just recently had replaced my whole system and come down to it, i happened to swap my cpu for an upgrade while i was at it, and changed the cpu and added the stock cpu fan, and BAM! she POSTs.... bottom line, check the cpu fan as well.

Good tip, thanks for sharing : )
What if the fans don't spin up? 500 watt power supply is 20+4 pin but my motherboard is a 24 pin. Could that be the problem?
Many modern motherboards require a 24 pin power connector + an additional 4pin connector connected to another socket. The 24 pin connector generally can 'snap-off' the last 4-pin module in order to acommodate older motherboards that only require the 20 pin connector. As to not confuse the two different 4-pin connectors, both have different shaped housings so that only the correct 4-pin connectors can connect to any given socket. Now, given all of this information, is EVERY power socket on your motherboard properly connected to the power supply, or is there a power socket that has no connector connected to it?
I like to think so but there is an 8 pin connector that I had a 4 pin plugged in from the pwr supply. My pwr supply has no 8 pin connection. I will unplug everything and try and start over. Oh, should I take the ram out too. I am stressing so bad and I hope that the board isn't bad.
joesgotmore
RAM can be disconnected if the PC is making no beeps but is powering up, otherwise it can remain. Perhaps the 8-pin socket requires the two 4-pin connectors connected side-by-side? I dunno, I haven't seen this configuration. Try your best to ensure that all power sockets have connectors connected to them, and if not possible, perhaps you will require a different model of power supply unfortunately : \
Sometimes the simplest of answers can fix the most difficult of problems. I unplugged everything and plugged it back and eureka the fans spin and I can get to the bios. Only to find out that I haven't connected the CD drive either because it has the old ribbon connector. Getting a new one from Newegg for 16 bucks. Wish me luck and thank you so much for your help.
joesgotmore
Heh, nice. Glad things worked out and best of luck with the PC remaining stable : )
helpful. thanks. i have an old pavilion p2 stock and it sudenly started the on sufden off shit. i csnt wait to try these tips.
Hope things worked out in the end.
we have an all-in-one computer. HP pavilion 20. no display. fan running. power led on. no hdd activity. no beeps. no bios or logo on start up. when i removed the just ram, it made the beep. when i returned the ram, there's no beep. when i remove just the hdd, no beep. when i remove the optical drive, no beep. i might not have flushed the bios completely, though. but i'll try that again. but let's say i've already done that. does that tell me the ram is faulty?
Sadly it could be the motherboard that's finished. Try 'breadboarding' the PC as best as you can, considering that its an AIO: th-cam.com/video/_EK9a-R5pss/w-d-xo.html
All my fans and LED lights turn on, you can even hear the HD working, no display though. Then has 3 short beeps that repeats. I took out the ram and installed new one, turn on PC all fans and LED lights turn on but now no beeps and still no display. I have no idea if it's the PSU or a dead CPU or a ghost haunting my computer case and trolling me.
Any thoughts?

i have GA-970A-D3 motherboard with no jumper pins (i dont know why) ..so how can i do it with no jumper pins ?
+Veselin Pavlov If you see the CMOS battery (coin cell), remove that, disconnect the power feed, press the power chassis button (to discharge remaining power), leave the PC as so overnight, and then reconnect everything afterwards.
all fans are going less are on I unplugged all components plus I installed a new processor but it won't work plz help it says no signal on monitor when hdmi is in but when out it says no cable connected????
+Lhucid 'No signal to monitor' simply means that your device is getting power, albeit not outputting your video. Did your machine function normally with a different processor?
Man, it seems that you're a PC expert, so I hope that you can help me.
Yesterday I repaired a 'no POST, no signal' PC with the help of this video, but my own PC is a little more difficult.
So, the problem is, that my PC restarts when I play. (Asus f1a75 MoBo + 3870k APU + 6670 1GB DDR3 VGA + 8GB DDR1600 RAM +LCPower 500w PSU.)
But the most weird thing is, that it restarts only once a day. So I play f.E. FIFA14 for 1 hour, suddenly it restarts, but after the restart, I can play as much as I want, no more restarts.
What do you think? What could be the problem?
Heh, wow, not as simple to diagnose sadly. Normally in this case I'd point to the code as the culprit, that is to say, either the FIFA game, the operating system, or one of the running programs is causing the issue. Of course, this can also extend to drivers, peripherals, components, the possibilities are endless. If not code related, perhaps it is in the way the video card handles this game, not sure sadly. Best I can tell you is that if your PC absolutely has to automatically power cycle when playing FIFA, best get that auto-reboot out of the way early before playing FIFA. Sorry I couldn't be of more help : \
RodneyDickson Thak you for the answer!
Actually, FIFA was just an example, the problem occures during any games, the only difference is the playing time... There are games, which I can play for 3 hours before the restart, but there are others, which I can play only for half an hour...
I tried restarting manually before playing, but it didn't help, The restart during playtime still happened, as usual.
I tried to run an AIDA64 stress test, but nothing happened during it.
An there's something, that I didn't mention in my last post.
I bought my PC with an N-Power 500w PSU (which is a crap, I know), and worked perfectly.
But after a year the PSU died, the service replaced it with this LC-Power thing.
That was the point where the problems started...
Could the crappy PSU kill something? If yes, how can I find the wrong part?
I asked experts in hungarian forums, they told me that this PSU was not enough for my PC, and I had to replace it with a 500w 80+ thing.
What do you think about it? May it solve my problem?
Csaba Tóth
Well, here's the thing: I can't say for sure if your problem is power supply related, but I myself keep MANY PSUs on hand in case one ever dies (so I don't have to run out to the shop to purchase one in such a case). That being said, it's never a bad idea to have one extra PSU on hand, so what I would try in your case, is to purchase a different PSU (perhaps more powerful or a better quality, just ensure not to purchase the same make and model of PSU that you already own) and from there, install the new one, give it a try, and see if it causes the same issues or if it solves them. Also, if the new PSU doesn't solve the problem, try a different power supply cable (swap with that of your monitor for example) and try a different power outlet (including a different power bar if you are on one of those) as some outlets or power taps do not provide an adequate or stable feed of power.
Hope this information helps and hope things work out : )
Thank you for your answer again.
I've managed to solve the problem.
I bought a new PSU with 80+ Silver certification, and since then, my problem went away. :)
Actually, the problem was not only the PSU, but in some aspects the mobo as well.
The new ASUS boards have a feature, called Anti-Surge protection. It can be activated or deactivated in the UEFI menu.
This setting detected, that my PSU was not too stable under pressure (while gaming) and restarted my PC to save it.
So after deactivating this feature I could play without the restart issue with my old PSU, but I think it's safer to have a reliable one.
So I bought it, re-activated the protection, and works fine.
So, thank you again! :)
Csaba Tóth
Ahh, good stuff! Glad things worked out in the end and thanks for updating us on the ASUS UEFI feature. Enjoy the gaming : )
Quick question, what about when it comes on, then turns off, then comes back on? I don't manually turn it off or turn it back on manually. what could be causing this??
When it comes back on, does it remain stable or does it turn off and on again in an endless loop?
When it comes back on, it does remain stable yet not posting. I went to my grandpa, he said it may be a problem with the power supply, which I will be able to check Wednesday. I also have another question, if i try to change out my power supply, and the other components have been damaged by water, can it kill my PSU if i try to test it out and see if that is the problem? I'm not one hundred percent sure the parts are water damaged however it is a possibility
Yes, this can cause damage to a power supply. Since your machine is not posting, I'd try what is shown in the video with the parts that you do already have, and if no luck, then I'd bring it to an electronics recycling center.
I recently acquired an old and rather dusty Intel Aspire desktop. The first time I plugged it in, it immediately turned on without having to push a button with a continuous beep. I had to unplug it to shut it down. Every time I plug it in since, it will boot for a half-second then shut down. I carefully cleaned the inside, removed/swapped/dusted the RAM and its slots. I individually turned it on with the same result after swapping just about every wire. However, I did some research and found that the likely cause was a bad CPU or power supply. I removed the CPU and subsequently its fan. The PC stayed on this time. Is the CPU bad? Or is it still possible it's a bad power supply?
Heck, it could be a bad motherboard as well. Unless you have a spare motherboard, CPU, and power supply to perform swap tests, you may never know for sure. I'd breadboard the machine (see 20:20) to iron out as many variables as possible without having to go into electrical tests (of which I know nothing about sadly : \
LAN not working:Invalid IP Configuration. Firstly, my ISP is fiber-optic w/o a router that comes in on an Ethernet-only cable. This is non-wireless & wired only. Don't care for the WiFi thing. I've tried all the cmd prompts, cables checked, tried other PC's that all work fine on same Ethernet. Also, even reformatted with new HDD. It worked at first after formatting. Then, I turned it off & the same thing happened with next power-on. I've got many other PC's(build them) that can be unhooked from Ethernet & reconnected over & over again w/o any issues. But, this one Asrock FM2A75M Pro4+ mb will not continue w/ working LAN. I did catch a nasty virus while on a test bench but it was reformatted after w/ new HDD. Could the problem be a physical one w/ the LAN port? Or, could it be a virus within the actual firmware/BIOS or is my ISP causing the issue w/ this one PC only? Doubt it. Please let me know.
Ooh, I couldn't tell you about viruses, but this is the way I'd test all of this: firstly, if other WIRED connections from the router are working fine using other devices but not on the AsRock, then we can assume that the problem lies in the AsRock machine. Once the operating system boots to the user interface, I'd disconnect the network cable, wait 10 seconds, then reconnect. Take note of the 'wired network connection' icon in the taskbar system tray and ensure that it does not develop a yellow yield / caution ! symbol. If it does not and it shows a standard wired connection icon, then open a web browser and type anything into the search bar followed by pressing enter: see if something comes up. If not, then click on START (or the Windows key) in the RUN space, type without quotations "cmd" and press enter. From here, you are going to type the following lines without quotations: "ipconfig release" then press enter, wait for the confirmation, then type "ipconfig renew" and press enter. A connection should attempt to be reestablished (once again look to your taskbar system tray icon for notification that a proper wired connection has been established). Once this is done, perform the web browser search test again. If still no luck, you can go into Device Manager and ensure that the LAN adapter is functioning as intended, and if no signs of problem, you can then disable followed by re-enabling this adapter in Device Manager to see if this solves the problem (confirm with the web search test). If STILL no luck, you can check in your Windows Firewall to see if anything is being blocked there for some reason (set your network to Public while in there). Finally, as a last ditch effort, you can uninstall your LAN adapter drivers and reinstall them, hoping that will work, and if it still doesn't, I recommend you purchase an ethernet card and use that instead of your onboard LAN port (check kijiji for this if you do not want to pay full price). Good luck with it all.
When I turn my PC on, it will power on for one or a few seconds, power off, then repower on again for one or few seconds, power off. repeat x times. This happens several times, but at random intervals it achieves the motherboard splash screen, often stopping there for longer than normal, and then either restarts the repeating process, or displays a black screen (staying powered on), or starts windows. On average I would say this process to finally get windows to boot takes about 15-20 minutes, but it can start just fine the first time, or it can take 2 hours. Could a short circuit cause this while still allowing the pc to eventually boot to windows?
Absolutely. Short circuits cause system instability in this fashion (sometimes you can be lucky and run your machine for many hours, whereas other times it may run for but a second or so). The PC fights to stay stable and functional through the shorts, and once it cannot take anymore, it shuts down (this threshold varies). Hopefully the suggestions in this video will help you solve your issue.
RodneyDickson Thank you for the reply!
grakowskyj
You bet. Hope things work out : )
RodneyDickson I fixed it, after bread boarding it. Turned out it was not a short circuit (at least I don't think it was). I have a dual bios board, and it would keep switching between the two bios (which is why it kept restarting). I flashed both and now it works perfectly.
grakowskyj
Ahh yes, I've heard of such a system before. Don't know what's the sense in having two different BIOSies, but I guess the manufacturers they have their reasons. Glad you got the issue fixed.
Ok, so I'm down to just the motherboard, CPU and PSU and still have no beep. I tried my PSU on another computer and it's working fine so I know that's fine and the problem is either my CPU or motherboard, is there any way I can diagnose which one is faulty?
Sadly you would require another CPU that is compatible with your current motherboard and/or another motherboard that is compatible with your current CPU. Finding a computer shop that accepts returns on opened items will permit you to test one of these, and if it doesn't work out, returning the product to test the other.
RodneyDickson Thanks for the reply :) I've ordered a cheap Sempron 145. So when I put the new CPU on, if I don't get any POST diagnostic tone from the motherboard speaker, can I say definitively that my motherboard is dead?
antiduckable
Well, nothing of this is 'definitive' (for example, who's to say if both the CPU and motherboard are fried?) I find the choice of a Sempron curious (I hope if the machine does end up running again, that you use it strictly for web and office stuff (no gaming or lofty video processing). Nonetheless, I hope things work out for you.
RodneyDickson I've just purchased the CPU so I have a known good back-up CPU should this ever happen again, there's no way It's staying on even if I can unlock the other core. Hopefully my motherboard does show some life and I'll get an FX-8350. Finger crossed! :)
antiduckable
I wish you well with it : )
You forgot to mention that if that the pc boots for a second or two then shuts off that this could be more so that there is either a heatsink issue if there is dirt or particles in between the CPU to heatsink or Heatsink to Fan that sits on top of the fam etc etc and its the PC merely protecting itself from overheating so it shuts itself off, this happens alot with people smoking around there pc and leave there computer in a dusty dirty environment. If the risers or any metal is touching the board itself to cause a short circuit you would see a burn mark around the area of the short circuit and you would not be able to start it again. New motherboard needed unless the board is more recent and has surge protection inbuilt which not all have. How do i know I am a qualified Technician with 10 years experience Diplomas and what not.
Ahh yes, the CPU overheating. Good point. I take for granted that those with this issue have their heatsink and ventilator properly installed with no damage to either. Thanks for the heads up : )
hi rodney i watched ur basic troubleshooting video and i liked it now i got a serious problem and i hope u will help me solve it i have my pc for like 2 years my problem started last month we have an electricity problem in my country so they have to cut off electricity and that kept happing to me until last month when i try to power up pc nothing appear on screen no beeps i suspected there is a problem with ram i removed my video card first power on again still no beeps no post tried each ram alone both working but they won't work together so i decided to use 1 ram then i put back VGA card power on pc still no beeps or anything tried the other ram with VGA card it worked but when windows logo appear it keep getting into BSOD then it keep restarting so i turned off the computer then removed cmos battery then turn on pc it get into desktop now i tried to put cmos battery back it get into BSOD after boooting so now i am working without CMOS battery now what is the problem with my pc?? my rig is Intel core 2 quad Q6600 motherboard : msi p45 platinum , ram : kingston 2GB DDR2 bus 800 * 2 sticks , VGA : Sapphire AMD HD7770 vapor-x, PSU : HEC 450 Watt (last thing i changed 2 ram slots because one ram i got before killed my slots) thx :)
Well, the simple answer is that chances are your motherboard has sustained damage and now will never function correctly again. The complex answer would be that perhaps you can find the right combination of components that will allow your PC to be usable despite running into said issues in the future. As crappy as it sounds, sadly with the state that the PC is currently in, I'd A) find the working combination of components B) reset the CMOS and C) format the HDD and reinstall the operating system from scratch. Sorry to not be too encouraging here, but this is the way I see the situation. Good luck with it all, and btw, they do sell power bars that regulate the flow of energy beyond what a simple surge protector does (I know, I use one myself). It might be something worth looking into for your needs (here in Canada they sell for around $30).
tnx. Sir Rodney..
+Crisging Enriquez Good luck with it all : )
i don't have the jumper for the cmos. This could be a problem?
i notice also that there is only 2pin ans beside it, i see CLR CMOS
leo mas
If there is no jumper cap on that 2 pin CLR CMOS jumper, then covering it will function as the clear CMOS.
still the same problem...:(
leo mas
If you are trying to clear the CMOS, unplug the PC, disconnect the button cell battery, press the power switch on the PC, then leave the PC as so overnight. After at least one night (can be more) reconnect the CMOS battery, power feed, and your CMOS should be cleared.
nothing change snif snif
I have the same problem but after retrying it like 30 times it might start up what could be the problem!
I'd breadboard the PC and see if it boots without issue every time when out of the casing. If it does, then contact with the metal casing is causing the issue. Skip ahead (fast forward) to 20:20 to find out how.

Thank you for your help! I had to clear the C-MOS but i hadn't got a 4 Pin C-MOS clear only a 2 Pin and i had to have the Battery insider! After Clearing and settin up the BIOS again my Pc Worked! (; Sorry for Bad English (;
snx1999
Ahh, good information to know! Thank you for sharing and glad things worked out : )
I recently went to upgrade from 2GB RAM (DDR2 PC2 5300U) to 4GB RAM (2x2GB sticks) with the 4GB installed my PC wont boot, the CPU spins up, the lights on the case come on, but i have no keyboard or monitor lights, the RAM runs perfectly in another computer also going from 2GB-4GB and the 2GB RAM in the other PC works in my PC, is there a problem with my PC having over 2GB RAM
+ell law Could simply be an incompatibility with those RAM modules or with their speed. I'd try different RAM. Also read up on your board to see if it has max RAM limitations.
+RodneyDickson yeah it was a problem with the ram compatibility, recently built a new computer, now have 16gb, will never have a ram issue again hopefully haha
+ell law Best of luck with it : )
Look i bought a sapphire radeon 6870 gpu, used it for like 20 days, it worked perfectly, but one day i was leavin the chair and i hitted the case, a small hit and the pc turned off, everything worked good until that little hit, i changed to another graphic card and it was working, the radeon 6870 fans spin, idk whats there
Sadly the only thing I can suggest is that you install the 6870 in a different machine (perhaps a friends or family member's machine?) and see if it still functions. If it does not, check the card for any burn marks on the contacts or possible damage on the components of the card (such as the capacitors). Other than that, the only other thing I can suggest is that if it has a in-store warranty, try to return it for replacement, and if not, try to RMA it (but this obviously costs a bit of money to do so, but less than buying a whole new card)
I am having a similar problem fans work lights work motherboard light is green except it turns off briefly and restarts, it doesn't beep because i donot have a case speaker, i have breadboarded it out of the case and the same thing happens
+Stuart Rogers It's good that you mentioned that you breadboarded it, cause that was gonna be my next tip. Did you try breadboarding it with only the following components connected: onboard video, CPU+fan, RAM, and power supply?
+RodneyDickson yes
+RodneyDickson i even bought a case speaker and 1 day shipping and it did not make any beeping so i rma'd the board
+Stuart Rogers Hmm, most likely you did the right thing. The next step would be to check the CPU pins for damage, but hopefully the new board won't give you the same issues.
