My PC keeps experiencing random power loss. This is not a thermal issue because when it is up and running it runs at about 35 degrees. This has been happening for months but the frequency of the power losses changes. Sometimes it will lose power while in bios, sometimes it will get to the desktop before losing power, occasionally it will lose power before post. Once it starts and has been idle for 5 minutes I can sometimes start intense programs (Premiere pro/after effects or Assassins creed unity at Max settings) and it will run fine all day. Idling or using less intensive programs like google chrome or file explorer can cause a loss of power after about 5 - 20 minutes.
Things that I've tried to fix it:
Replaced 750W PSU with a Corsair RM1000W
Stopped using case power switch incase it was causing a short
Swapped CMOS battery
Flashed to latest BIOS
Tried a clean install of windows to rule out any software conflicts (Formatted HDD and then experienced a shutdown half way through windows 8.1 install)
I have a new Mainboard and CPU on the way. If one or both of them is busted anyway, I may as well do an upgrade while I'm at it.
Is there any way a GPU could be causing random total shutdowns? I don't see any video artifacts and the GPU itself seems to be performing fine. Could this be anything to do with the HDD even though after a total format it is still shutting down?
