I have been plagued by sudden restarts of my system for over a year and it is just getting worse. No blue screen and in event viewer i just get a generic Kernel-Power error (all BugcheckCode values are 0) it just restarts It used to happen with mostly very GPU demanding games so i suspected it was just my GPU overheating. And the temps on my 780 under full load got in the high 80s and if not for my system restarting i was sure it would go even higher (My new 1070 has never gone over 70 during full load still restarts so not a overheating issue). after capping my frame rate with RTSS lowering settings and keeping and eye at all times on my GPU temps i was able to reduce the problem at the time but it would still happen from time to time sometimes even when i was just watching a video. It also often happens 5 minutes after i am done playing a game and just browsing the web which seems to indicate it has trouble adjusting the power down or something?
Usually, it restarts in a second but sometimes it takes up to 30 mins for it to reboot again. (no fans spinning just seems dead then it eventually wakes from the dead) I suspect it's waiting for the capacitors to discharge. After the pc has been off for the night it can also takes 15-30 mins for it to power on (usually not when it's hibernating just when i turn it off) so I'm not so sure what that's about.
It has gotten worse recently and I'm pretty clueless about this stuff and i dont trust my own assessment if i buy a new PSU it will be a downgrade from what i had so i really would greatly appreciate a second opinion. Could it be caused by a faulty motherboard? Or do you guys think its pretty safe to assume its the PSU? I dont have a spare one to try.
The pc is also pretty clean as i dust it off often. I also have checked that there is nothing loose.
