Ugg, I hope to one day track down what is causing this PC to crash 1+ times a day.

Random lockups, usually while doing NOTHING. It rarely crashes when doing something.

Is there a good way to determine what component is causing the crashes? I doubt it is the CPU Overclocked, because even at low settings, have the same result.

Windows reports no issues with the RAM, maybe I should test with another app?

Prime95 running 1 thread on each core completes with NO errors.

Same results with 501,704,804, and soon i'll try 903 (804 was the worst due to VDIMM bug)

CPU is not overheating during crash, neither is GPU.

CPU: QX9650
MB: P5E3 Deluxe/Wifi-AP
RAM: Corsair XMS3 1600mhz 7-7-7-20
PSU: PC&C Silencer 750
GPU: eVGA 8800 Ultra

very random crashes. Sometimes BSOD, sometimes not.

Set everything in BIOS to MANUAL and tried many settings.
