I genuinely didn't know this was going to happen. I thought it was just a dusty PC 😅 Just in case anyone's thinking "weh you could've saved that" - this had an E2-3200 (FM1) CPU in it. It was not a good APU. It was the worst APU. This PC was not worth saving.
I got to 1:20 into the video and had to come check the comments because I thought "There is no way in hell it's worth fixing that piece of junk, what are these people thinking?"
@@Pekeliini I love the ivory towers people inhabit in the comments. Last week I had a call from a secretary of a small electrical business whose owner knows my brother. The PC had become unusuable and their company payroll was on it (Sage), could I help? Budget to fix was zero. The PC was unbranded with an MSI H61M-P31 (G3) M/B, a Pentium G860 CPU, 8GB DDR3 and a Toshiba 1TB HDD It was indeed unbelievably slow - even to get into Windows 10 settings was a wait of five minutes. Did I throw it in the bin and demand they shell out £500 on something new? No, I cleared off all the junk such as AVG and the other million things in startup, virus scanned and chkdsk and Auslogics defrag (Thanks Graham). Then I recalled that I had a Core i5 3450 and 4GB sticks of DDR3 doing nothing. Put them in and the PC actually worked well in dual channel mode no less. The upshot is that any time I want electrical work done for nothing just ask. Any moron can say "Anything less than a Ryzen 5600 is scrap", it takes a bit of understanding of other people's situation to actually help.
@@reggiedixon2 cool story bro. It's nice that you were able to do free labor and parts for that small business owner. Makes is a lot easier for it to be "worth" saving when it's completely for free. As far as I'm aware Adamant IT doesn't work for free. So it's already a cost to bring it in. Sure, the computer in this video is also worth saving if you just change the MB, CPU and PSU and not charge for any of it.
People will struggle on with really bad systems as long as they still actually work 😩 I often find myself having to convince people to upgrade for their own benefit, despite the fact that technically I'd make more money infinitely fixing their old PC.
The key thing to understand here is that often the brain of the people using these computers is working at the same level of performance and reliability as the computer in question. That is why they continue using computers that basically don’t work and don’t even see the problem.
In most cases, it's not about money. You'll often see people with garbage computers from 2013 who, paradoxically, are using the latest, high spec smartphone. So a good many of them either have the money or are willing to go into debt to buy the latest bauble, but they want to waste resources on a shitbox from 10 years ago. Strange stuff.
Nice demonstration of fault finding by voltage injection without using a thermal imaging camera. Bet you're glad you didn't have your finger on the MOSFET. ROFL

Whenever I get a rig in that won't turn on and trips the PSUs SCP like the stock PSU did in this one (which is technically a good thing), first thing I do is unplug the 4pin 12V and try to turn it on again after waiting 5-10 secs for the PSUs main filter caps to discharge and "release" the SCP so to speak.

You have a short on one of the power rails as it turned on for a second. The correct procedure would have been to spot the fan spin. Realise the PSU protection came on. Find the short and replace the chip(s). Not risk blowing up your send PSU and now the CPU as well.
Great video, I've had to clean out plenty of dusty junk boxes just like this, but never had the pleasure of watching them burn a little 😃 Thanks for sharing!

@@gd2329j NO WAY! That happens to be one of my worst recurring nightmares. How did you know? Freaky. You are all knowing and basically RoCk, GD*J Cheers
Gday mate. Just recently subscribed. I've gotta say I loved the outdoor dusting. It had that real 70s Flying Circus feel whered they'd be shooting in the studio then they'd switch to film for an outdoor bit. Looks like you live in a nice part of England
Keep the new Air Blower, you previous device with high pressure and Low Air volume is the wrong device. Lower pressure at higher volume is perfect. Keep this new Blower.
In some of your other videos with laptops you have said if the light on the charger is on and you turn the laptop on and it immediately goes out, it usually means there is a short. You unplug the charger and plug it in again and the light resets itself. Would that have applied here as well since there was a light on the back of the power supply?
Shorts on a desktop motherboard are really uncommon, so it's just not something I expected. On the other hand, a dead PSU that cuts out the moment it's put under load (start up) is very very common.
Yeah, I didn't go straight to that idea, but I did find it quite odd for the PSU to turn on for half a second then shutdown and I was rather surprised Adam thought absolutely nothing of it.
@@Adamant_IT So I will add this step next time I see the light on the desktop power supply go out after hitting the power switch, to unplug it, let the PS reset, plug it in and see if it comes back on again. If so, it looks like early warning detection of a possible short and possible flames :)
When researching if having a ridiculously oversized power supply in a PC (e.g. 750W for a low end CPU with no graphics card) is a bad thing or not, one of the downsides I had found across some forums and websites is that if a component were to fail in a way that it short circuits, such as the motherboard in the video, because the PSU has so much reserve power, it is more likely that the component that short-circuited goes up in flames than the PSU's overload protection circuit actually activating. Well this video happens to be a good example of that, although in this case the overkill thousand watt PSU wasn't pre-installed in the PC - it was just hooked up temporarily for diagnostic purposes only.
often enough the consumer pc's get garbage PSU's and wouldnt be surprised if the one in this pc actually damaged the motherboard when failing i dont know how many hp computers ive picked up that someone gotten rid of because of a failed PSU
Yea this is an interesting conundrum, a few people in the comments have remarked that the Antec _appears_ to have less protection than the stock HP PSU... but as per your post it's not quite that simple. IMHO, this isn't really something you can plan for, or that is worth anticipating. If you're working on devices where you're expecting a short circuit, then yes, you check first... but when building a PC, I don't think you can feasibly plan for this. There's also a theory that multi-rail PSUs are better than single rail because the maximum wattage per connector is limited, thus limiting potential damage, but this antec is a quad-rail, and still managed to burn down a high-side.
The Antec 1000W "short circuit detector" PSU worked perfectly! But seriously, there are many more low-quality high-power PSUs than low-power PSUs because high-power PSUs are sold to the general public who are ignorant about PSUs and believe more power is better, while low-power PSUs are sold to corporations (such as HP) who care about legal consequences and care abut their reputation. If an HP computer burns down a home, HP might have to pay all damages. If that Antec PSU starts a fire, then well, it was the motherboard that failed. Not Antec's fault.
@@Adamant_IT i do some pc work here in the states i havent see that happen but i dont work on a ton of stuff primarily just for friends and family but 2 of my builds used boards that was from HP as i pulled the boards from the case and put it into a custom one for my personal stuff
Wrong move buddy! :D That old PSU is most likely perfectly fine and I was convinced that it was something on one of the power rails that's shorted. If it was an internal short in the PSU, in 90% of the cases it wouldn't jerk the fans into a "quarter-spin" like that. At least that junk box proved to be full of excitement after all! :)
Good to see you let those dust bunnies back into the wild behind the shop. I’m looking to get one of those blowers instead of going the compressor route, so look forward to review.
I have a 7800 GTX GPU from 2005 that did the exact same thing, PC suddenly shut down, restart gave me quarter fan spin and PSU would go into protection mode, let everything cool down and started again and suddenly there was a burst of light coming off the back of my GPU, actually singing the cable for the CPU cooler fan. I don't think the failed component was a power MOSFET though, looked like some sort of logic gate
I've been using that electric duster for a few years now and I like it, however the bottom is the intake and as you are dusting you will find that it will clog the bottom as the dust gets sucked up like a vacum as your blowing out x device. You have to clean that filter on a regular basis. Overall I like it and saves money instead of buying canned air. Also, unlike an air compressor unit too, you cannot change the pressure of the air flow.
Ha that was great! Also there was a small flash a few seconds after you unplugged it, off to the right of the cpu. Maybe it wad just a lens flare or something. My desktop is an amd A10 7850k. Ancient really. Can't get Linux reinstalled due to some issue with 1 of the 4 cpu cores getting "stuck". Windows runs fine but of course the graphics aren't that great for the 3d graphic work I do. And is barely ok for streaming my telescope through OBS. I could probably throw in a new psu, but I don't want to really throw more money into it and it really wouldn't fix the issue. I just need to break down and build a new system or buy a laptop.
Regardless of whether it was worth saving or not, would replacing the MOSFET have worked? Or would the fire have damaged subsurface traces or other nearby components?
It's probably welded itself to the board. But the PC has been written off by the customer (not exactly surprising) so I might at least do an autopsy on it for the sake of learning.
Excluding the aspect of cost,would the system still be fixable?Replace the blown mosfet and you're good to go, or the chances are that the CPU is also dead?
@@TheSpotify95 Or you just install Linux on what is for bloated Windows "a shitty piece of garbage" and it should work okay. In fact, scratch that - it WILL work okay because I have one running Linux as we speak. It's bloated Windows, not age, that makes some PCs unusable.
Could replacing the mosfet alone solve the fault? Obviously not worth it with this board. I have a MSI B550 that had a very similar fault the cpu mosfet glowed red, I shut it down and has been in my might-try-to-fix pile since.
Possibly. Need to replace the mosfet driver as well, as a bad driver might just be holding the mosfet on - and thus will blow up any replacements as well. I've only had a go at shorted CPU VRMs once and couldn't solve it, replaced mosfets and drivers, but still kept failing short. And each time you test it, you kill another chip. I might've just been unlucky though.
If we assume businesses exist to make money, I don't see the point in spending any time on this from a business owner's perspective. Valuable as far as demonstrating voltage injection and whatnot, but if a customer brings me something like this I just say, "I'll transfer your data to a new computer but I'm not touching this".
Im not very knowledgeable in Motherboard repair, I watch alot of Northridgefix's videos. If that short circuit was a direct short to ground, could you have injected voltage and replaced that mosfet?
I genuinely didn't know this was going to happen. I thought it was just a dusty PC 😅

@@TheSpotify95 Or you just install Linux on what is for bloated Windows "a shitty piece of garbage" and it should work okay. In fact, scratch that - it WILL work okay because I have one running Linux as we speak.
It's bloated Windows, not age, that makes some PCs unusable.
That PC was lit ngl, 4 real it was unexpected that to happen, good on the explanation on why tho :D
Could replacing the mosfet alone solve the fault? Obviously not worth it with this board. I have a MSI B550 that had a very similar fault the cpu mosfet glowed red, I shut it down and has been in my might-try-to-fix pile since.
Possibly. Need to replace the mosfet driver as well, as a bad driver might just be holding the mosfet on - and thus will blow up any replacements as well. I've only had a go at shorted CPU VRMs once and couldn't solve it, replaced mosfets and drivers, but still kept failing short. And each time you test it, you kill another chip. I might've just been unlucky though.
Close your door when you dust man, sheeeeesh. that was a blizzard. 🤣
Clear demonstration of why power supplies that can push too much current trough a single rail can be dangerous...
Never let the magic smoke out of your components LOL
If we assume businesses exist to make money, I don't see the point in spending any time on this from a business owner's perspective. Valuable as far as demonstrating voltage injection and whatnot, but if a customer brings me something like this I just say, "I'll transfer your data to a new computer but I'm not touching this".
You gave it a Viking funeral ;)
Looking forward to gear reviews!
Im not very knowledgeable in Motherboard repair, I watch alot of Northridgefix's videos. If that short circuit was a direct short to ground, could you have injected voltage and replaced that mosfet?
Graham , do you not have a power supply tester that you can use first to see if the power supply was really dead?
"I going to take this out back and give it a good" kicking...
Four! I mean five! I mean fire!
