Computer keeps randomly shutting down and resetting BIOS

post #1 of 2
Thread Starter 
So lately my computer has been shutting down randomly often in less than half an hour, even in low intensive sessions. Sometimes it will reboot back on its own in 5-10 seconds and sometimes it won't and the only way I can boot up again is by removing the PSU from my power outlet for 20 seconds. Also, when I do boot up again the computer hangs on POST and I have to go into the BIOS to reload my OC profile because it resets my BIOS every time it crashes.

I'm using a very high quality Corsair AX850 psu that was RMA'd just a few months ago, so I don't think the problem could possibly be the PSU again? Any help would be appreciated.

Does it do it without the overclock?
Have you used Task Manager(or even better, Process Explorer) to see if something is hogging up memory?
Have you looked at Windows Event Viewer to see what was going on just before a crash?
