I have answered many of the questions and comments in today's Live Session (Friday 21 Feb 2020: How To Troubleshoot A Motherboard - Live Pt 3 Computer Tuning On But No Display On Monitor th-cam.com/video/3Ir6FlPei1U/w-d-xo.html)
I just swiched my processor cooler and when i start my pc then my mouse and key board doesent light up and my screen says:no signal. Please help!
I fixed it i just had to take it out and put it back...
No fan spinning but the psu is still giving power, tech fixed last 2 months by using small metal and touch something on the board and it turn on now the problem go back and i dont know how to fix this
Im just a dabbler in these things, and I just came across your video.
What a joy to watch.
Quick question/request: Can you make a video -or add within one of your videos what the post beep tones are for? I dont know if every manufacterer has their own set, or if there's something universal. Thanks in advance if you can!
I'm trying to add Ram to my computer from 8 GB to 16 GB. I got the cards from the same place and are the same and work separated but together the computer doesn't send a signal to my monitor and doesn't start up properly. I know both RAM slots work but I need help.
Awesome diagnostic tutorial format for virtually any home user. Good clear spoken instructions, just enough detail to avoid problems. I have seen MANY you-tube tutorials, yours ranks with the best!
Bro dont doubt yourself for not being a good speaker, you clearly explained and showed everything in detail. Good work!
I appreciate your straight-up non-flashy style. Good work.
Hi bro. I've recently stumbled upon your channel and I wish that I did sooner! Excellent content and method of delivery. I would consider myself a novice - decently experienced person (built a few rigs myself) and I have managed to learn a couple of things from you. Wishing you all the best! Cheers from Malaysia. 😁👌🏽
Honestly the most informative explanations, keep up the good work man
You are welcome!
Good to see someone who takes pride in their work, and makes sure every part is working by testing, then retesting.
Great work.
Please show how to check each components with multimeter so that we can find where is the actual prob in a dead motherboard
Ugh. I wish i saw your video way before i bought a new monitor and new ram. :( Great job, you thought me stuff that i never knew. Much support
Clear language, detailed explanation. Keep up the good work.
Thank you for the support!
yes your right
I'm amazed at how hard you're pushing things into the board, bending it a bit. I'm afraid to do anything like that! lol anyway, your videos are so helpful. My new pc I was building didn't turn on . i'm about to do this out of box test, recommended by asus.
Thank you very much for the tips. This process of elimination that you suggested helped me put an end to the constant blue screens my pc was experiencing for the past years (probably due to a faulty ram slot).
I'm glad I came across this video, while facing a similar problem. This does justify the likely fault
I totally thought it was a matter of either powering on before, or after plugging in display, mouse and keyboard.
nice video was hoping for more in depth component level tests as this is what i am studying ATM and like you said most engineers will not go that far have a couple of boards which do not start the fans and will enjoy the challenge if i get enough time to fix them good luck for the future my friend
Thank you for very useful video, RESPECT.
what a smart man, you're awesome !!
One thing I don't think you mentioned, sorry if you did and i missed it, but first thing I do is get a magnifying glass (eyesight at close range not the best) & check for bent pins inside the socket. You;d be surprised how many motherboard issues are due to bent pins.
Cheers mate!
You are so good and telling me what to do with my computer to get back on. Please do a few more with other faulty pc equipment.
Hey great video. I have done every thing you have done but place a test mother board in place. So I learned from you that the mother board carries the start up function.
this helps me a lot although i ended up replacing my motherboard because its dead.. just like my technician said..
Thank you for speaking clear english, it really helps :)
Great video my friend, you have helped me identify the issue with my board. Speaker cable ftw
Very good video for beginners. My students watch and understands more better. Thanks Bro.
I just had this problem tested everything i needed and now i am for sure, sure that my motherboard is dead thanks to this video lol. Thanks mate it helped. Also hopefully in 2020 you are not using a drill to put in the screws.
Was the motherboard the issue because I’ve been having issues where my pc doesn’t turn on but it’s receiving power because the LEDs on the motherboard turn on when I plug it in. I’ve tried anything but I believe it is the motherboard
you're such a good teacher, congratulations
Truee
Awesome.👏 Thank you so much sir for a useful video
Well done brother , well explained ! I couldn't risk to skip a second 😅
Nice'
Very good video. Thank you for your video from Texas!
Great work, Thank You.
I'm having the same issue, but the motherboard does have lights, and they do turn on. The issue is that it's io won't work, I connect the monitor, keyboard and neither turn on.
Hey, did you manage to work on it and if so, how?
@@f2carter93 yeah, it was something really dumb, the Mobo had to be updated to accept the Ryzen 5 3400g.
Well that's something....I have the same problem. Planning to take it in for checking....Thanks
@@f2carter93 Ur welcome
Samuel Lin was it a b450 motherboard?
thanks for the video man.
i was moving around the power and reset + - pins to turn on the pc. but i forgot to turn unplug the computer now my pc i dead.
question do you think it can effect the CPU as well. can it be dead as well? i realllyyy hope.
thanks for your video and time
IF its power then you should be checking the PSU, and front panel connection to the mobo for power as well...in terms of CPU dying, its quite rare but not impossible if there is a short...
U deserve many mire subs n views for being simple n technical
Thanks for the encouragement, feel free to share to help out the channel!
@@HealMyTech1 i actually got a problem wih my system thought u could help
So this is what happened
I had an old pc and planned to upgrade the mobo,chipset basically the whole tiing with a a320 asrock+ryzen 3 1200 cpu.
I built the pc today but it just didnt want to post i tried literally everything ,clearing cmos .....etc
Im not sure if its cpu,ram or mobo but i am damn sure the gpu aint faulty cuz on the old system it worked but only on a restart the first boot always began with onboard gfx and i had to restart from bios to get the dedicatedgpu running (probably the cmos problem) but i dont think thats the main issue for the ryzen build i hope u read this and try helping me i am very frustrated
I'm sure doesn't matter if your test purposes however you did not mention replacing thermal paste after removing your CPU fan.
Correct! There are many other things I didn't mention in the series, consider this a pilot, one day I will muster the courage to redo this whole series more professionally!
Great video!!! And thankyou!!! I might have to do this my pc stopped powering on a few days of installing my new GeForce gtx 1660 however even though nothing not even the fans power on the gpu blinks on and off has anyone else had this issue?? Would appreciate any feedback
Did enjoy the real 1 cut - 1 shot video .... more practical to get the teaching out there than to make it fancy!
So you thing I should of more of these, they are easier to do as they require no editing, but usually involves a camera person which i don't have and the topic must be something i am very comfortable with that I can do off the top of my head without planning, scripting, or rehearsing...sounds challenging...!
@@HealMyTech1 yes. Thats how i do my videos. (See the sandi91361 channel).
I believe and I've heard it said that people value genuine transfer people who are real and humble. Normal day-to-day people like me and you don't have time to edit videos and the things we have to say do need to get out there. I bought three mini tripod from China I think four about 4 USD each. They hold my phone well. Prior to that i would prop the phone/camera against something and it frequently fell. But better then nothing right? Rarely do i have camera ppl to hold the camera. And when u need to change tbe view to point to something else, just say excuse me please while i switch tbe camera. this also adds a bit of adventure. And can help the viewers to feel more involved. You get better at it with time. And u learn to plan a bit before u start filming as to logistics (where and how).
Also its good if something does go wrong so u can demonstrate ur train of thought and how to troubleshoot. If u dont know tbe answer to an unexpected problem, tell ur audience just that (the truth) . And tell them how a person moght find the answer to tnis later.
Superb videos of ur playlist..
Very helpful, thank you.
Masha Allah thank you sir from India
Try an older video card, with lower specs. The tech manual for the motherboard SHOULD tell you both the type of Ram, ram settings and jumper pins for the CPU and/or video card. Make sure the CMOS has the CPU, memory and correct video card settings; otherwise it will NOT start up properly.
Can you do a video on the dangers of popping out the CMOS battery, as the way it jumps up makes it a newbie favorite duh! All those lost settings.
Wow this just came p in my feed.
I have been wanting something like this for a while.
I like the way you lay the computer parts out on the desk - we don't need a case!
Where did you get that switch to turn the computer on - the one that connects to the front panel headers. Or waht is it called so I search Amazon etc.
It's a simple button that exists in any Desktop Computer.
It's a wire attached to the motherboard and goes all the way to the front of the PC (Or the top) and is connected to a button that powers on the PC.
The Power On switch has this inside it. It's in every Desktop Computer.
Beautiful video sir!!
You might want to add, "clear the cmos". This will normally be one of the first thing to try if a mainboard doesn't start.
i have this at my first build. Now ive learned about all possible problems and still only 2 options left. PSU or motherboard. Since its brand new and was pre assembled and supposedly tested i sent it back to the shop inbought it. Next week i will hopefully now...
No post sound, but lights on, tried various input cables(HDMI, DVI,) took off power from graphics card, what you think?
I had the same issue except my build would restart loop, is this a sign of a faulty mobo? i used a known working psu and that wasn't the issue. i ran it with the bare essentials, psu, cpu and mobo but no beep and it continues to loop restart.
Hello, I have a HP Formosa motherboard and an i5 LGA 1155 CPU. I encountered the no display issue after I cleaned the computer dust on the CPU heat sink, CPU Fan and the chasis fan. I have been troubleshooting this for about 5 days with no luck. I replaced a working GPU, no display. I removed the GPU entirely to see if I get any beeps, none... I do get 5 short beeps when I remove the RAM. Can i assume that the MB is fine here? No external devices are attached at this time, including kb, mouse, gpu, usb, DVD, or HD. If I replace them back, no beeps or no display.
Can you please help me what would be my next step?
thanks and keep up the great work...
thanks for helping and educating that means a lot to me
My pleasure!
Thank you bro keep it up good work Mashallah
i think a dead mother board won't allow the power to go through it to the other components, so if it was really dead the fans won't spin and nothing will turn on
Does the USB ports get power during a dead mother board??
Beware of youtube advise. A Mother Board is a very complex piece of electronics and have had more and more functions added to them over the years. They can malfunction in many different ways including no power to any component although I would check the power supply in that case as well.
Thats the problem im experiencing.
Light Yagami what if when the red LED shows up on the motherboard , and it doesn’t make a beep sound? What if when I plug in my m&kb to the mother board USB ports they don’t work or turn on? Surely there’s something faulty with my motherboard than?
Would the hard drive's disk still spin?
If I have unplugged all devices, my computer boots sometimes gets past BIOS, but it shuts down very timely usually inside of a minute, possibly two. I have replaced the power supply, and I think a bad CPU wouldnt allow me that far. Any ideas?
You should probably try to reset the bios( hard reset), short the two jumper pins for the CMOS with a screwdriver for at least 15 seconds, that should reset your bios. You don't really need to give any power to the motherboard, the charge from the battery should help. Hopefully it helps you
Hi goodmorning Sir! Please tell me how to fix my computer, its automatically turning on even im not pushing the power button and there is no display in monitor tell me what is the problem of my computer
Nice info
you just give me the answer i was looking for. i got a new motherboard to swap it for my old one. so i swap all the cables & i plug them correctly after i turn on the pc but no image in my monitor everything else was working the CPU & GPU fans.
Great Video I was wondering why my old pc would not start up, fans on everything and light up but not boot. motherboard is dead
Thanks for these tips, i just realized that for some reason my motherboard cpu pins were bent. Thats why it wont boot properly, no busted resistors on my cpu
Whats the update?
@@HealMyTech1i tried to fix the bent pins, but it still wont boot(im not good at this) I'll try to fix it again once i bought the tools i need.
i know im very late but do your cpu wiggle a lil bit on the socket when bent ?
@@J03M. it didnt at all, my pins were only slightly bent. If it does wiggle then i recommend to let the pros fix it or just buy another intel motherboard.
I have tested my power supply and it seems fine. Now when plugged back in to the Motherboard it stops running (no fans spinning). My pc is totally dead but originally, I got 5 beeps when starting up (asrock 970 Pro3 R2.0), but after two or three times it died completely. Where do I go from here in the analysis, is it the front panel (which seems unlikely since I got the initial responses/beeps) or somewhere else?
Thank you so much!!
How do i fix a newly built custom pc thats having slow transfer speeds? And any drive i plug into it pretty much crashes or freezes immediately I already updated everything and nothing works as it shud it shud be flawless
I have a question.. So everything seem to power on in my pc but I have no display. The cpu fan, graphics card and fans are all on but their is no display. I tried plugging hdmi into both the graphics card and one at the top of it
Rock Roll yeah I sent my mobo back in return for a new one so I’m waiting for that.. I believe that the board I had is just messed up. I mean everything powered on and what not and I trouble shooted it. My cpu is perfect and my graphics card is working. I even took the graphics card off and booted it but still yellow flashing. My ram is confirmed that it’s compatible with my mobo so it has to be a faulty mobo.. I ordered a speaker for the mobo just Incase, let you know the update in the next week or so though
WavyGoCrazy Hello there!! I’m experiencing the exact same problem!! Did the computer end up working after fixing the mobo?
@@jayayejay3972 did u fix it
@@milplayer17 No bro :( I still got it in the closet rn to try to fix it up again. Please let me know if u solve it!
@@jayayejay3972 well since i troubleshooted everything my only guess is its the motherboard. Cpu didnt look damaged
Hello sir,my PC has this problem,I have changed hard drives severally but despite all I do,the best or the furthest the computer goes in terms of starting is showing me the windows starting window n never goes past that,the drives are ok.....what could the problem be?
My motherboard that I orderd works fine as 1st time I tested it then I put it in the case then it wont turn on. Whats wrong?
Did you set it to wumbo?
when i press the power button my pc starts and shuts down immediately then again starts and shutdown immediately. amd this happens again and again.
my power supply is new and outputs correct voltage. so please tell me what is the problem.
I tried to run the system without processor then the motherboard is running. is the processor is faulty?
Was your mouse and keyboard working (showing any lights) when you were testing the faulty motherboard
Did you get any answer?
My desktop can be turn on until select safe mode, safe mode other and normal boots.
But, then it just turn blue screen.
So the problem normally is mobo or proccessor?
I also notices, 2 pin cpu connector was bend.
I got my old desktop pc up and running again after being in a cupboard in bits for a few years. It was difficult getting it working but I managed and it was running great. The case was damaged so I bought a new one and swapped all the parts into it but it wouldn’t POST. I tried all your suggestions but nothing works so I swapped everything back to the old case and it still won’t POST. I’m at a loss now. Do you think the motherboard has broken in the swap over?
Hey , I was able to fix pc troubleshooting with the help of RYANSROOM617 on instagram Or text him on WhatsApp +1 442 233 0240.. he’s an online technician and a pro hacker.. you can try him out and his service is affordable 💯
While using my pc there was a blackout then when the current was back i turned on my computer but theres no power i tried 2 different psu’s but still no power so just want to ask you sir whats the problem thankss..
I haven’t received my cpu, or gpu yet, but I decided to put together the rest of my build anyways to see if everything else work. When I hit the power button nothing happened, no fans turned on, nor did the front panel LED. Ugh, it’s my first build too. I’m hoping it’s just a faulty power supply.
Do you think some flex in the mobo while plugging in power due to missing standoffs could have damaged it?
Its possible but unlikely.
Probably the computer didn't detect a processor and refused to even post. If there is a led light on the board then check fr that.
I get no beep at all, i have checked the psu with a multimeter and all is fine, i have taken each individual component out one at a time and still no beeps, but the fans power up and lights come on (no startup, black screen) is this a fault with my motherboard?
Sure sounds like that...have you individually tested each component apart from just removing them and reinstalling one at a time?
Very clear explain bruh
amazing explanation thanks bro
Have you tried removing the Cmos-battery to reset the BIOS or replacing it with a new one? If that doesn't work then it should be PCIe port on the motherboard that is faulty.
i would also try removing GPU, and ALL RAM and see if you get a beep then, also most of the times clearing the CMOS will do the trick
you are amazing
Very nice.
Thank you! Cheers!
thank you
I have a new build that I just can't get to work. I have checked everything. The PC starts, the fans are going on the case, the CPU and GPU, and it stays on for 15 seconds, then switches off, then restarts for 15 seconds and this repeats until I turn the PSU off. What can I do next?
So how do you trouble shoot a brand new motherboard that isn't getting any power? I tested the power supply and used the jumper to test it already, but when I plug in the power to the mother board and the CPU there is no power going into the motherboard. I have a motherboard with a built in VGA card and have RAM in it but there is no power going through the power supply. This tells me that the motherboard could have a pin problem with the connector because the power supply would at least turn on with a load right? How do I test my pins on the motherboard or should I just return it back to newegg and get another one?
Hi Sir csn you advise My Pc what is the problem,
Becauase theres no display on Monitor,i already clean the ram and gpu and comos, still no display..but my PC have power and Fan...when you turn on...
hello,for my case when i connect the psu ,there is deem light on the motherboard and a funny sound in the speaker like"tututututututu"like a flour mill machine please help
hey man for everyone that tool for power button is useless just use a screwdriver that isnt fully metal as the handle cant be conductive and then tap pins turn on
My pc now boots but putting screws to hold vCard makes it not post. Or putting in a pci wireless card makes it not post. No lights are on the Ethernet port. No internet. Didn't post before but now it at least posts. Is it shorted? Or now bad motherboard?
Bro can I get some help pls?? My pc isn't working, no display, starts normaly but it isn't even entering to the bios :'(.. i really need help with it
Thank you
Very nice
I TESTED MY PSU WITH THE paperclip method, when i did that every fan (psu, cpu,gpu) were spinning.
but when i reconnect the 20 pin to my motherboard it wasn't working.
My pc wasn't turning on.
doesn't that mean my motherboard is the problem???
how will I able to know which thing is the culprit ( jumper, port,cmos battery etc.) on my mobo?
Same same
Just built a new PC with all new parts and I’m having a difficulty booting it up. I see no display on my monitor however everything on the motherboard when I tested it is lighting up and seems to be working fine. I built my PC then unbuilt it to try and fix it and can’t seem to find a solution.Any help??
what did you do to fix this?
every time i plug in my psu into my cpu 8 pins it doesnt boot but when i leave it unplugged it turns on but no display. would it be a mobo issue or processor?
Same situation I have
ToxicPuffin did you ever find a fix to this
Hi, thanks for the great video! My games are constantly crashing after 5 to 10 minutes. Could it be a motherboard?
I've checked temperature, updates, graphics card, memtested ram. Any ideas on what it could be? THanks in advanced!
I would start with an in-depth PSU troubleshoot if I were you, video on my channel, but there is a more recent one called: Finally solved Annoying PC Which kept crashing & Restarting....check it out and let me know how it goes....
Hey max, if you still have problems, try driver easy! it updates drivers that windows say are up to date. My system was randomly crashing, after update of the drivers everyting works.. At least worth a try
@@HealMyTech1 Sorry, must have missed this. Thanks for your reply. I watched the video. Definitely a power supply issue causing the GPU to falter, I turned down how much power my GPU used to 75% and had no problems. Thanks again for your help and great content :)
I currently have that problem but i do get the beep, my gpu fans are not spinning, im not sure what it is but the mother board lights turn on but no signal to the monitor and mouse and keyboard light don't turn on.
Is the beep a successful beep code for POST or a different code?
Hi brother my desktop now still have the same like that and on my mother board frontpanel like restart powerHDD , ....not working so how can i do?
What should I do if I get no display and my ports don't work
My motherboard posts, and there is a signal sent to my monitor, but no display... I tried changing the ram sticks with working sticks. I changed the PSU to a working PSU. I'm thinking it's MB or CPU, but CPU has no visual bends in pins....
My problem is that the power supply is running, having static electric on the motherboard but cooling fan is not running and is not turning on !! Please advice ?
Can you reply sir. I don't know if my mobo is dead. I switched PSU, RAM and HDD and still nothing. My monitor says no display but my system turns on. When I turn on my system the fans and hdd are running and in less than a minute the cpu fan will suddenly slow down and still no display. Is the mobo the problem?
Good video ;)
How would you trouble shoot a amd b450 that locks up after working correct for up to 36 hours switch back to a320 board with no problems.had to wait months to get a b450 board?
Is it possible for the board to die soon after installation? Just finished my 1st build and it was working perfect but the day right after, I wouldn't get any signal to the monitor, no post or anything. My dram led lights up but I don't think it's the ram, I tried my other ram sticks and they also wouldn't work which I knew worked on my other computer. I also reseted the cmos but same result. And like I said, it was working perfect the day I installed windows so I'm just really confused and getting real frustrated. Any help would be appreciated
My mobo b450m hdv r4. 0 is beeping 1 time which means memory refresh error... What do I do now..... It suggest that the mobo is faulty 😱😱
