PC randomly rebooting on its own

Hi all,

I'm currently having a problem where my PC will randomly hard reset (no BSOD or warning) during non-processor intensive tasks (such as editing a Word document), but has yet to reboot during CS:GO or watching 1080p movies across 3 monitors. This has led me to believe it's not a temperature or CPU/GPU issue.

Also this doesn't seem to be a software issue. When the PC reboots, most of the time it "struggles" to get through POST. When the PC shuts down, it will stay off for several seconds, before the fans spin back up for a second. Then stop. Then start for a few more seconds, then stop, etc. But eventually the PC will boot back up again.

For how long it stays up is also quite random, but it can stay stable for a few hours, maybe even a day or so. This is making this problem really hard to nail down because I have no sure-fire way of reproducing it.

Obviously this is a very general description of hardware failure, but could you guys give me some pointers on what I should be looking at first, or what the potential causes could be? For the record, I've also reset my BIOS to defaults.

I'm not sure if this is relevant, by my fonts folder recently got corrupted which caused BAD_POOL_HEADER BSOD when trying to open the Fonts folder, open Firefox, Microsoft Word, etc. However I fixed this by resetting my Fonts folder to Windows 7 default.

This problem also occurred a while ago when I was crossfiring 2 6950's. I removed one and haven't had the problem in over a month, leading me to believe the graphics card was broken. Is this a PSU issue?

Here are my current specs:
  • Intel i7 920 (originally overclocked to 4.0GHz; water-cooled)
  • Corsair Dominator 6GB PC3-10700
  • Asus X58 Sabertooth
  • MSI Radeon HD 6950 Twin FrozR III
  • Corsair HX 750 Professional Series

Many thanks in advance, it's really hard to work from home with a PC that's rebooting on its own accord!

go to c:\windows\minidump

is there some .dmp files in here? if so attach on to this thread and ill analyze it for you. the .dmp file should have the date of the crash attached to it. most recent will be fine.
 
I just crashed an hour ago and the latest minidump is from 3 days ago (when I fixed the BAD_POOL_HEADER BSOD). Do you still want it?
 
No, that dump fil will have been off the BSOD.

Could test your memory for good measure

hit the windows button bototm elft of screen, in search bar type windows memory diagnsotics. then at the top fot he search column yoou should see the program. click it and restart.

if it asks you on restart which mem diag you want to run pick the most intensive.

Also could check event logs to see if theres anything in here?

start > right click computer > manage

open event viewer left hand side, check application and system logs around time of crash. anything in here relating to the reboot?
 
The event log contains nothing interesting, really. There are no event logs relating to the shutdown, but it whinges a bit after restarting:

Kernel-Power (Critical):
"The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."

Kernel-Power (Error):
"The previous system shutdown at 14:29:15 on ‎10/‎09/‎2012 was unexpected."

Also memory diagnostic showed no issues :(
