I have a problem with my machine I've been battling for months now. It will just randomly restart and I could be doing anything. It has happened when browsing the web, playing games, and even when the motherboard logo shows up during startup.
It never seems to crash when running Prime95 or OCCT stress tests.
What I've done:
Hardware
-Re-installed windows twice
-Purchased new motherboard
-Purchased new CPU cooler (from air into liquid)
-Purchased new GPU (HD7950 to GTX780)
-Purchased SSD
-Monitoring software showed PSU 12v rail running at 10.8v when stressed. Checked 4 pin molex connector with voltmeter and it measured 12.2v and it dropped to 12.1v under stress.
-Changed the case, thought it was a short circuit somewhere.
Software
-Run multiple stress tests which did not cause a crash.
-Ran Prime95 and Battlefield 4 at the same time. No crash
-Updated GPU drivers
-Updated motherboard drivers
-Can't update BIOS, scared computer will restart during the flash. My motherboard revision is 1.01 and
-I've run memtest for 5 hours, but I should do it again
Sometimes, instead of a restart, my display will turn off and any sound playing will begin to loop. PC will be unresponsive.
CPU temps reach only about 35 degrees under full load.
