PC won't boot anymore.

[Juuna]

Hi everyone, I have a problem with an AMD A10-5800K which was giving me some high temps while gaming, something around 70-75° with the max temps of the CPU being around 75°, obviously when the CPU reached this temps it would shut down. This build isn't mine and it's one of those "mini PCs" with small cases and everything is kinda cramped, and there was quite a little bit of dust inside, even though I'm not the owner I decided to clean it.

 

After cleaning and taking out some dust it didn't get much better so I tried replacing the thermal paste, it wasn't Arctic MX4 quality or anything like that instead it was some #@*$ low quality paste made in the country that there was in the house, as expected it didn't get much better but it dropped like 5° so now I was gaming at 65-70° or so. This was like a week ago.

 

A week passed, I wasn't having any troubles with the computer shutting down until today while I was playing it "restarted", fans were running but the computer wasn't booting. First I tried removing one stick of RAM which seemed to work but after opening two programs (Discord and Firefox) it turned off and wouldn't boot once more.

 

I cleared CMOS because nothing seemed to work and it booted, even though now because of the reset the fan wasn't running at full speed like it was previously I opened a game to test and the computer turned off again, Open Hardware Monitor was showing temps around 50° before this so at this point I'm not even sure if it's the CPU temp, I cleared CMOS once again because it wouldn't boot and it booted, I turned it off and left it there so I could try to find any solutions online.

 

Just now I was about to test the memory with memtest86 but now the PC is not booting again and nothing that I do seems to make it want to boot, this PC is not mine and kinda makes me feel bad that this happened while I was using it so, any ideas or possible solutions?

Board CPU or PSU is shot.

 

No way of knowing without swapping one of the 3 parts. I'd start with PSU first. If a good working PSU doesn't help, that motherboard is probably shot, VRMs likely cooked, Cpu .... from the sounds of it has been cooked repeatedly.....

 

It doesn't sound promising man.

Okay so I got it to boot again, not sure if I was resetting the BIOS wrong all those times, after all it's the first time I've done it with a jumper, if I test it with something it may break again but it's there something we can discard with this?

Can you re-word that last question please?

Before it wouldn't even boot and now it does even though the problem is more than likely still there, u suggested swapping components and see how it works, I probably only have one working generic PSU that I would have to search and can't provide other mobo or cpu to test since I have none, but based on the fact that now it does boot, can we discard any of those components mentioned as the source of the problem?

Did you just blow the dust out or did you do a full teardown, clean, reassemble ? Dust very often can be conductive enough to really mess with boards after a while.

If you left the cmos jumper in the clear position and try to restart the board and it was failing to post, then yes disregard the components mentioned.
