PC powers off after several minutes, not power supply issue.
Hi there, sorry if this or a similar issue has been posted before. Several hours of googling didn't help me solve this issue.
I built my computer last year and recently it has been powering off instantly between displaying the BIOS info and displaying the windows booting animation. I have noticed that if I leave it turned off for several days I can get six or seven hours of uninterrupted usage before the computer powers off. However if I try to boot it up a few minutes after it has just powered off, it shuts down almost instantly. I thought it was a power supply issue and so I just replaced my 450w supply with a 650w one. I got about two hours of good use from the computer with no problems, restarted it, and it powered off during the windows animation. I'm totally at a loss. The computer shuts off when I navigate to BIOS setup and just leave the BIOS screen up doing nothing, and also shuts down in safe mode. This is super frustrating and I've got no idea what to do next. Thanks in advance for your help
