I've been trying to troubleshoot this PC for a couple weeks at this point. It's a Frankenstein build with extra parts I had lying around so my partner could play PC games with me, so I'm not 100% on the specs.
So, she's been able to use this PC for about 5-6 months with no problems. After this point, it would start randomly restarting. We observed this behavior while gaming because that's all she uses it for, but we didn't test to see if it turns off otherwise. After about a month of this happening, it would then start losing power, or sometimes restarting, after about 10 minutes or so of being on at all, regardless of what was happening. I thought this could be CPU temps, RAM, PSU, or the power cord fuse. Following those suggestions, I tested and replaced the RAM and PSU (Neither seemed bad, but I wanted to be sure), and also monitored the CPU temp, which got to about 70° C at most. None of this changed the restarting/loss of power.
After this point, I suspected hard drive. I replaced it, and after plugging in a Windows boot USB, it was able to stay on the install screen for at least an hour with no power problems. I installed Windows, and it lasted 3 hours on the home screen.
I updated Windows and... Without even restarting the desktop to apply updates, it once again began losing power, which now happens every time it finishes with the "signing in" Windows screen. :/
The only difference in those situations is that while diagnosing, I had it plugged into the wall, whereas while updating, it was plugged into an extension cable with other components plugged into it. Can this be a cause of this issue? I'm at such a loss and am so frustrated with it, I just want it to work for her. 🙁
I also tried some system diag with... I think it was called WMAP? I can't fully recall, I just know it was very technical and I couldn't understand a thing on it.
Any suggestions super welcome, and thank you for your time.
TL;DR: Partner's desktop loses power/restarts nearly immediately after the Windows "log in" screen, and I have already replaced the PSU, RAM, and ensured the CPU isn't overheating.
