I had the same error and after much trouble shooting on my brand new built pc, you know what the problem was?
A Belkin usb wireless adapter.
Caused by some stupid cocking cock faced cock sucking process cock that no one on the internet had heard of, something like "steamsurge" (nothing to do with valve)
Disabling that in my USB driver thingy fixed it GRRR...
Now i get a random comp restart every couple weeks unrelated i think because i dnt use that POS anymore. BSOD caused by NVGTS.sys or something like that, which i've tracked down is my SATA driver (i only have 1 SATA hardware and that's my DVD drive)
Other times me PC just restarts, no BSOD, i've stress tested my PSU and i've ran MEMtest+ and no dice, i've started logging it down though and making note of any application/system errors at the time of restart, see if i see a pattern.
The last restart was on 30th of December at 1945 >=( So random!
Hope you've fixed your problem anyway, not hijacking the thread
