WTH?.... I'm an electronics tech (10yrs) and retired USN electronics tech (20yrs). Isopropyl alcohol (IPA) is a VERY common pcb cleaning solution. Now it should be a high purity (99/98%) and not the generic rubbing alcohol (70%) from the local pharmacy.
Little tid bit of knowledge, IPA (at least the ones with high purity) do not conduct electricity.
AT2 (HSL-41, 1988 - 1992) here. I used to "wash" my hands with copious amounts of Trichloroethelene after avionics maintenance. Worked great! Causes cancer. Today, brake cleaner and/or WD-40 is the solvent of choice, for cleaning my computer parts. But, yea. PURE IPA also works well... Drugstore 70/30 has a LOT of water, which can damage computer parts/electronics.
What about 91% gotta use that cause Walmart never sells 99%. It works for me and I have tried 70% once which works too but I let it dry overnight cause it’s pretty close to 50% too lol.
@@strawberrysherbet96 Gotta work with what ya got. I'd do like you already are and extend the drying time or give it a bit of a bake. The lower purity ones will tend to leave a film though (this may or may not bother you depending on what your cleaning). Cheers.
Pure water is non conductive as well its the ions in it i.e. impurities that conduct
@@strawberrysherbet96it's fine to use the '91% especially if you make sure it's dried out pretty well. Take the component and kind of fan it in the air, that will throw off any unevaporated liquid. Just don't pull a Linus and launch it across the room.
Never had a problem using IPA to clean computer parts.
Im betting the person knew the motherboard was screwed and was looking for a free replacement.
Person is probably a kid that didn't know anything.
Given the water damage I think not
40usd and he would got a new mobo he doesnt kniw anything or give yo thinking it was beyond repair
should have gone to Greg Salazar if he lived in Orlando FL.
And it works for most retailers who don't understand or bother to check what the customer is saying but trying it on with someone who does is a bad mistake.
I think using IPA is a good solution. The fact that it not only does a great job removing dirt, but it also evaporates very quickly. Recently I did acquire an old beast and it would not work at all. Hit the power button and it would shut off 1 second after pressing the power key. I pulled the board out, and there were dust bunnies on the back which I assumed created a short. I cleaned it up and wouldn't you know it? It works completely fine. That was just with a good brushing.
I like 91% usually. It evaporates quickly, but not too quickly like 99%. I'm just careful not to expose the plastics to it too much.
I scored a pretty darn good deal on an RTX 3080 yesterday for $330, it's the ROG Strix version as well, some guy was just trying to get out of town and was needing money and I obliged. I'm going to try to run it in a dual GPU configuration with my RTX 3060 12gb for machine learning and stable diffusion. I snagged a be quiet 1,000 w power supply, to run the 3080 on Amazon for 99 bucks!
That's like a sore pecker, you can't beat it. Have a good one man take it easy. Enjoyed the content. 🤘🏻
Fascinating on how your patience with this paid off. One could definitely use your expertise in diagnosing issues such as this. Good video, M8!
I would be curious to see what would happen with the original motherboard once you cleaned up that water damage spot.
Almost 20k subs congrats! Learning a lot from your vids
Congratulations on over 20k subscriber's!! I am pretty new and checking out some of your videos.
You're kinda starting to make me think of a PC side hustle. I'm a chef for my main job but i have a computer addiction myself and it would be fun to work on them as a side gig.
Love the videos man.
some motherboards have a BIOS setting for behavior when power is restored, and you can have it just boot up. Problem you've replaced the CMOS battery many times so that setting ought to have reset by now. I think the board is kaput since it doesn't even give beep codes. If it was a working mobo, it would still give beep codes if it had no CPU and/or no GPU.
awesome video just like you i have also PC enthusiast and i build and repair computers for fun and i like watching you do your thing and trouble shoot and custom some of the stuff you been working on keep it up love the feedback, content and issues I may or have not come across before.
In your first video, at 15:10 you were asking about the pattern on the back of the board. That is a tale-tale sign that the board has been HOT!!!. I used to work for a repair shop that had some success reflowing solder and fixing a dead board using an oven. It does work some of the time, of coarse there are videos on YT about it, and because of that many people try it themselves to varying degrees of success. All that boards that we reflowed using the oven looked nearly identical. Why you might ask. It is the rosin cooking out of the 60/40 solder.
It tends to be temporary in my experience it looks like its worked only for it to break down again maybe weeks maybe months later but its will happen in the not too distant future
Hi, it was entertaing to watch when someone else struggling with cheap pc builds, not me :D. Hd audio conector is next to audio jack block. Manual helps a lot with rekognision of board topography. Cheers from Poland.
Restore power after AC loss is a setting in the bios that will cause the machine to turn back on if there's a brown out or whatnot.
really enjoy ur videos!
Good result, nice video.
I just purchased one of those keyboards, love it. Fortunately, water only damaged motherboard.
I watched both videos pt1 and pt2, i'm really trying to learn since i'm an ameteur builder. I would suggest getting a window unit air conditioner for your garage. I do all my work in the garage, it helps so much. Thank you, really enjoy your videos!
Okay, I went back and watched the other video again as a refresh on what people were complaining about, and I'm sorry but if you think spraying IPA on a motherboard and cleaning it with a toothbrush is bad... then you're probably not the "computer technician" you think you are. You cannot damage an electric circuit with a neutral liquid if it's powered off, and there are liquids that you can spray on it that can't damage it even if it's powered on. For applications where they can't have downtime, they take a pressure washer to industrial power equipment and servers... while they are powered. This is a special blend of chemicals that are not conductive, which normal people won't have, but you just need to remove power first and fully dry it before powering it on again. As for the toothbrush... nothing wrong with that as long as you aren't ham-fisted neanderthal and you just get overly aggressive. I've brought so many mobos back to life use this method. HOWEVER, I would absolutely remove the CMOS battery first.
Also, I have worked for several PC repair shops and I run my own now... you need to know the laws in your state and how this is handled, but you just can't be expected to hold on to their computer perpetually. You eventually have the right to sell it if they don't ever come back to pick it up or they refuse to pay.
Ham-fisted neanderthal got me. 🤣
Get a supply of 1 pin dupont jumpers and you can extend any of those headers. Just gotta be careful not to screw up the pinouts. The jumpers are super cheap.
I would guess a dead or damaged CPU and then a bad mobo as the No. 2 reason.
Regarding isopropyl alochol, I've seen others uses this. I've done it myself. This works well as a cleaning agent, because as you know it evaporates quickly and doesn't leave behind any residue.
If the CMOS battery is under 3V its a good idea to replace it.
I would've at least used some thermal paste while testing the cpu just to be on the safe side, but aside from that I didn't really see any issues. As for the 2.5 inch drive, I'd recommend grabbing the 10 dollar icy dock adapter and throwing it in the 3.5 inch bay for propriety's sake to make it look a litte cleaner.
I've had the bristles from an "ultrasoft" toothbrush get under surface mount components and rip them right off the board before. That's why I only use a very soft paintbrush now.
Iso is fine to use, but not rubbing alcohol. If you can't get at least 99% iso then don't use it. In 70% iso, the other 30% is water. That's why it's bad to use rubbing alcohol. If you drop a phone or something in water, don't turn it back on. Dunk it into a container of 99% iso. The iso displaces the water, even if the water has gotten into the circuit board(s).
Also you can use chlorine-free brake cleaner as well. It tends to work a little better because it's pressurized.
Yeah, i thought it was, actually, the motherboard. I just had a hunch; i guess. Thanks for sharing!
Instead of using thermal paste, get some of the Thermal Grizzly KryoSheets. They're reusable from project to project.
To anyone saying that IPA killed this mainboard, you can run one of these through a *dishwasher* to clean it as long as it isn't powered on and is given sufficient time to dry. There's no way high-purity IPA did it.
You can get an M.2 to PCIx 4x slot adapter and reuse that M.2 drive on the new mobo. The mobo is new enough that the BIOS should support M.2 on the 4x slot via adapter.
I like my C3032s above 3V at all times. They are usually fine until its 2.7-2.8 but i have seen batteries reading above 2.9V that were causing issues.
FYI. I was at Dollar Tree and saw those cmos batteries. I was kinda shocked especially since i just bought 2 at Ace Hardware for 10.00.
I've stoped unglueing those cooler supports and swapping the hole backplate assembly... a T25 and 3 screws is easier than dealing with that stupid glue!
I believe they actually wash circuit boards with something like isopropyl alcohol at some point in the manufacturing process. I actually washed a shitty old PSU in my bathtub with soapy water before, and it was fine. I made sure to discharge it and sprayed it with electric parts cleaner after and blow dried it and let it sit outside on top of an ac unit fan on a hot, dry day for good measure.
So long as you remove all traces of water immediately afterwards it should be fine its letting water stand around that causes corrosion and of course any evaporation residue
Hey man, love you show. I have been doing computer repair/upgrades since the early 90's, before windows during the DOS days. Let me help, as far as batteries goes, the 2032 is a 3.2 volt battery new, any voltage below 3 volts replace. When you are trying to figure CPU vs M/B which is bad. In my life I have only had one CPU bad. Mostly look at motherboard when you have to pick between the two. Asrock make great motherboards, I have tried them all and finally ended up choosing Asrock, they work.
appreciate the info!
always best to check the battery in circuit if possible, anything below 3.0 volts, replace.
just a quick note- power automatically comes on.. if power switch still works- its usually chip related, if the power switch does not work-- its powersupply or shorted motherboard (usually) ... just a fast way to look for the issue- I was going to say it was motherboard but you found the problem..(motherboard) :) great video
I often use Vaseline as test thermal compound. Also, it tends to absorb old thermal paste from the CPU and heatsink, cleaning it a bit when I wipe it off.
Cean up on the back of og mobo where the corrosion was w alcohol & a brush & install a new mobo battery & try it again. It might come back to life...The psu will not start if a short like corrosion exists so it may work after cleanup of corrosion
Funny thing is 99% of viewers have your same experience level and shouldn't be calling you out on anything. R&R folks like to think they are automatically Techs, or because they built a system or two. Good luck, great videos!
You should ask for the diagnostic upfront. Let them know you will apply it to the repair. That is common practice. Even if you are not a professional, I assume you have a business license. If people think you are hustling them, show them your business license. Maybe open a booth at a flea market once a week. Can be a good place to trade and sell.
I had the same problem when I got my first computer back in 1999 from a clearing house company. I didn't know better back then and I didn't realize it was a used PC . It stopped working after a week and I sent it back when it came back it worked for a few days . Later on my friend look at it and there was no power going to the motherboard. Then I took it to a shop in Manhattan and they changed the motherboard and it worked after that.
I had the same issue with a motherboard, I would spray a ton of IPA and clean it up 2-3 times. Mine ended up working just fine.
Love your content sir! I'd recommend getting those graphite thermal pads (Intel & AMD sizes), that way you don't have to fly through paste 😉
Those tear easily and aren't really meant for repeated multiple use, they are meant to be installed once and forgotten about.
@@schmutz1g If you're talking about the thermalgrizzly ones, then yes. I found some that are much more durable by innovation cooling!
@@techromancer313 I'm talking about all of them, they were never intended for the purpose of repeated use.. you might get away with being gentle and reusing them but its still not their intended function which makes them a poor choice for testing and repair. The best solution is just a super cheap large ass tube of TIM.
@@schmutz1g 🫡
Should have cleaned the rust off the old MB. Retested it incase the rust itself was causing a short.
Auto start is usually a BIOS option the setting is called something like power on at AC restore .
cleaning the watter damage that you found behind the socket mounting bracket might of brought the mobo back being its corrision is conductive it can short the power turn on sense for the cpu and have a false turn on and it wont send power to the cpu
VHS,,,, Spelt HVS to the rest of us... And please clean that gunk off the back of the old board and try it again, maybe it was just a short and the board was stuck in a power loop if the power switch traces were shorted.
In my experience the motherboard is more times at fault than CPU for sure
A good test is to unplug everything but the cpu. No video, no ram, etc. You should get post beeps for ram and video. If you don't get any beeps, it's motherboard.
Welcome to the internet, where everyone except you is an expert, lol. I've been building, and using computers since the Windows 98 era, and I saw nothing wrong with your diagnosis, nor build. I've lost both a motherboard, and a CPU, and I can honestly tell you the symptoms are astonishingly similar.
Also, good on you for documenting everything, and protecting yourself. There are some really shifty people out there whom don't care if they're taking food off your table, or not. They've got no problems ripping people off, and as long as they get what they want out of you, they'll do it. At the end of the day they thought they could pull one over on you, and they ended up paying for it. Now you can sell it as a refurbished PC, and at least gain compensation for your troubles.
You would've gotten a beep code if the motherboard is good and the processor is bad. It's the motherboard that's bad.
Awesome. I thought the motherboard. Its almost always the motherboard or bent pin in my case. Learned the hard way. Start with the cheap fixes first.
I believe Greg Salazor just did a build with that mother board, his was an Asrock with no m.2 aswell. In my experience when it comes down to the MB or the CPU on a desktop system its generally the MB.
I use IPA cleaning PCBs a lot. It with power and battery removed conductivity isnt much of a problem and it dries fast without leaving resudue. Distilled water would be fine as well, but alcohol is a better solvent for crud.
I have had HPs and Dells that turn on as soon as they have power. There is normally a setting in the BIOS for that.
I also like using a known good CPU, I keep a celeron or Pentium from the different generations just for troubleshooting, they are cheap, maybe $15 each used.
Dude, do what Brain Tech, Yes City does, break cleaner, CRC, blower, ultrasonic with water and detergent and they come out squicky clean.😁😆😅🤣😂
It's a decent little rig. A shame you had to go through the spaghetti scametti for it, but this could be useful for e-Sports titles, modern AAA gaming with low settings, or just an all-around budget PC. Heck, maybe give it away as a gift or to someone who can't afford a PC?
that is typically what I do after the video is give them away to locals needing PC's
You removed the electric connection by knocking off the green crustys. Swab that area where the liquid was then give that mobo a try again. It might still be good.
I need to try that.
Regarding the original Omen PC powering up when the PSU was turned on, I have seen this behavior in many TH-cam videos featuring HP and Dell systems.
Would it be worth it to try a PCIe to NVMe adapter in the X1 slot?
By the way, you make great videos. Looking forward to the next one.
So for my back up PC, it’s housed inside a Lian Li PC08WX in black which was the predecessor to the PC011 versions. The case is fully Aluminum with tempered glass. Anyways, this was my main case for about 4 years before moving my main rig into first, the 011XL, then 011EVOXL. I have a Gigabyte Z270N Gaming 5 Mini ITX Board currently in it now. The only positive over what you did is it has the NVMe slot on the back of the motherboard. I was totally thinking to swap to a full ATX board, but for the purpose I’m using it for doesn’t fill the need. No extensions were necessary in the case as well.
I was thinking MB was bad - I have only had one CPU fail in my whole life and I have been building PCs since the 1990s.
Same here, Ive been building since the late 80's and I can count on one hand how many bad CPU's I've come across. 99.999% of the time its the mobo.
I’ve been working on pc’s on the side as well I find it fun
I watch another youtube channel on here called Adamant IT. I believe he said "It's always the CPU, except when it's not" while troubleshooting a no post issue.
Immediate power on is a sign of a bad PSU or cable connected to it. And check bios settings for power on after power outage.
frisbee? its a coaster maybe decoration lmao
just something that might be an issue is some motherboards are sensitive to which slots are populated by the memory sticks.
Nice find with the i7 10th gen, a very capable CPU.
Since you find out what was the problem on that board I would totally clean the board with IPA and I would test it again to see if that fix the problem
I purchased a 25L with similar issues. I'm fairly confident that Windows update pushed out a bad bios update that bricked the motherboard. I'd bet money that that is what happened here.
I have had the auto power on when power was removed while the board was learning a new configuration, i.e. after cpu or ram swap.
I'd detour and see if that water damage can be resolved before following through with the swap, gonna have to mess with all the cables, plus it's far more resellable with original mobo as a SKU and all the features there like m.2 etc.
Not sure if anyone has mentioned it, but in the previous video that he sold him a working i5 system (with a 1070) and that guy came back with an i7. Now, we find out it's a 10700F AND a 2060.
If anything, the fact that the customer fucked off and basically tried to "scam" him with a 10700 and 2060 (depends where you look, but a 10700 is still roughly $150-200 CAD and some 2060s are looking to be around under 200 nowadays), that's a win win with a mountain of cherries on top.
People are saying time was wasted trying to diagnose and fix this, I say- I spent time finding out I was given $400 instead! ($360 if you take into account of the motherboard)
It was probably over voted. Check the board for an OV jumper
There's nothing wrong with using isopropyl alcohol; I've been repairing computers and electronics for 38 years and have extensive experience in the industry. The concerns about isopropyl alcohol are largely unfounded-it's perfectly safe. In fact, you can even immerse electronics in a bath with dish soap, provided they're not plugged in, of course! Regarding the mainboard issue, the likely culprits could be power delivery, a faulty MOSFET, or the customer may have corrupted the firmware. Generally, everything during the post is managed at startup, and a classic sign of corrupted firmware is when issues arise at this stage.
did you clean the mobo off? a good tooth brush with alchol does wonders. that back plate comes off super easy too.
The 10th gen i7 is a solid cpu, still viable due to intel switching to 8 core that year. Its on my current rig the past 3 years andl doing the job.
Are you the type to harvest spare parts from dead parts? ie I/O shield, socket cover, etc from dead mobo.
Curious, maybe worth a try. If you cleaned that goo off the back of that Omen mobo? Is it possible that is causing the mobo to auto power on as soon as you turn on the PSU? Most like the Mobo is fried, but its worth a try to clean off that goo and see if it resolves the issue.
Did you ever try reseting/clearing the CMOS/BIOS on the motherboard? I don’t remember you mentioning this.
How much Green Crud was under the CPU bracket on the underside of the original mobo? Was it enough to cause a short? Could the orignal mobo be working now that you cleaned it all off?
That's a solid RockAuto magnet collection
You might be able to save that board- no idea how much the board is worth so it may not be worth the trouble, though if it is water damage it could just be a bad/shorted capacitor that needs replacing. Looks like this worked out for you in the end!
It'll be funny with you using this rig as a test bench so if the Person who tried scamming you follows your vids, they'll then get to see it many of your vids!
THAT RAM STICK IS A HP BRANDED RAM STICK AND ANYONE THAT SAID ITS MIGHT BE THE ISSUES IS RIGHT IF IT WAS DEAD BUT NOT BEING SUPPORTED HERES THE THANG OMEN IS OWNED BY HP HAS BEEN OWNED BY HP FOR A WHILE I BELIVE 2016
I check taht asrock motherboard manual and front panel audio connector is right next to rear audio connectors :D
I have more then once saved a PC I should have tossed in the trash. I exchanged a dead PC for one of my old spares... (all junk to today's standards really)
Was for someone I knew a long time ago and reached out to me. I gave everything for free as I like to help people.
I gave a perfectly fixed Core2Quad 6700, 8GB Ram, Radeon HD5700 (old)... 250GB SSD + 1GB mechanical... Windows 10... ran flawlessly. It's old but does the job.
I took his old not booting Acer FM1 AMD, it had a lower end A4 cpu (useless trash) and 500GB mechanical drive.
In short for the fun of maxing it out, I paid for the highest end CPU the board can take, and A10 which is a quad core @ 3.0Ghz with intergrated radeon.
Then I realized the motherboard was the issue, so I ebayed a replacement motherboard... and all in all... it's just a shit system that his brutally slower than a back then 120$ OEM 2nd gen I5 2400.
250$ CAD wasted.
Then again, I did it because it's a unique AMD and was curious to how it held up...
Badly is the answer... it's complete crap.
was the memmory doing training? due to having the battery out,also try the board without the cpu
or you could try flashing a new bios
i found corrosion on the board and showed it in the video
Did you look for the BIOS reset jumper? It is an HP afterall? I'm betting bent pins in the socket.
Did not see liquid damage coming.
As far as the IPA goes, even if it doesn't hurt, I just don't see it fixing a faulty motherboard. A bad MB is the result of some electronic failure, not because it's physically dirty. Of course it's helpful to clean a dusty pc, but air/vacuuming is sufficient.
Lastly you mentioned the motherboard was in there with only 1 or 2 screws? Then you are risking frying the board because of shorting it. Any contact with the metal case should be grounded with screws.
If the board does not even attempt to post like yours its worth trying a different bios chip or reprogram the one on there. If all the voltages on the board are there, i mean. Had a asus crosshair iii formula last week that did not beeb or do anything except turn on and off. Bios chip was bad. Also had this tiny short near the sio but taking the shorted part off and putting it back fixed that.
the only thing is I dont know if you tried it is reseating the cpu but if its the motherboard coming on its most likely something in bios or the motherboard burn I seen that too
One last ditch effort to see if that HP motherboard works or not is to clean the back side with a toothbrush and isopropyl alcohol and in and around the CPU socket to drench it in isopropyl alcohol and use a can or compressed air to see if anything comes out from uderneath the socket.
I tried that on 1 board and it worked. It's a 50-50 chance it will work you you unless something popped on the board.
Alcohol is fine. Even if it were lower purity like 70 the computer was off and it dries quickly.
I've cleaned electronics with alcohol for many, many, years and I have never had a problem with it damaging components.
I've seen so many of these 9th to 12th gen Intel CPUs just die at random, even under warranty. Custom builds and OEM. By comparison I see so many OEM boards from this same generation die versus the custom build boards have a much lower failure rate.
I have worked in IT for 20+ years so i deal with a larger quantity of PCs than most.
Mboard is usually the safer bet. Just more things that can go wrong.
My guess was old BIOS with a CPU upgrade not compatible.
The motherboard is shorting somewhere. Probably nothing you can do about it unless you feel like desoldering and re-soldering the whole thing, and even that's not a guarantee. If two traces are shorted, RIP to that board EDIT: Just saw the water damage, so I was sort of right. It was shorting. It'd be interesting to see if you can clean it up and get it running again.
I had a motherboard turn on by itself, it was broken
Suuure blame the neighbor 😂
Good day sir
It's a mATX board with 2 PCIe slots, just smaller that usual.
its possible the second drive sled might have 2.5" drive screw holes for the ssd.
