Random Computer Shut Downs

So my computer has been shutting down super randomly lately. Sometimes it’s immediately after booting into windows and sometimes it takes an hour or two. I’ve been monitoring temps/running stress tests and nothing has been overheating, my CPU is not overclocked and I lowered my GPU overclock. I’ve done windows memtest and nothing was wrong there either. I took everything apart today, de-dusted, reapplied thermal paste and made sure nothing was glaringly wrong. I also reset CMOS yesterday and that didn’t seem to fix the problem either. The program I’m running on my computer doesn’t seem to affect the crashes as it will crash regardless of what is running at that time. To be more clear, my computer black screens but does not power cycle or stop running, which is usually indicative of a graphics card issue, but like I said, it’s never going over 70C. The only weird thing to happen is that the last time it crashed, immediately after black screening I heard my GPU fans jump up to max power and then power back down. I’ll add my part list in a minute. I have a hunch it’s either a PSU issue or something with my motherboard. I do have a spare PSU that I’ll use to test either tomorrow or Monday, as well as a spare GPU.

Quite possibly a PSU issue, but look around for a busted cap somewhere, especially on the GPU

Do it, that'll tell you more than anyone on this forum can.

I'd guess it's the GPU. If the power actually cut out (PSU) the fans couldn't spin up. Mobo issue should cause a power cycle/complete shutdown. Of course it could be a weird PSU/GPU interaction with the PSU actually at fault, or the same with the mobo.

If it still happens with both a different GPU and PSU it's obviously either the mobo, RAM or CPU, but most likely mobo.
Testing the spare GPU first will be the easiest but be careful, if the spare uses less power then just because it's working with the spare doesn't mean it's the GPU's fault. It might still be the PSU so test old GPU + spare PSU as well, just to be sure.
