A few days ago I OC'ed this new build of mine to about 38% over. Memtest86 v3.5 said no errors, Prime95 ran for 24 hours no problem. Hasn't been turned on since Prime95 completed it's 24 hour run. Now 5 day's later, keeping in mine nothing different has been done other than getting hooked up to my network.
My hardware is an XFX 750i Extreme motherboard, and an XFX GTS 250 and the drivers for both were installed from the OEM disc included with them. Intel Core2 Duo E6550, 2GB DDR2 667MHz (in single channel mode cause only 1 stick) Kingston RAM, 600W PSU, Vista Premium 32 bit.
When Prime95 was ran CPU was OC'ed to 3.21GHz, motherboard was @ 1833MHz, The RAM setting were left to auto @ 333.3MHz 5-5-5-15 2T with a ratio of 11:8. With NO Windows updates (fresh install) but both GPU & mobo had their drivers, and was never connected to the virus-net, uh I mean internet. Never overheated.
Now keep in mind both P95 and Memtest86 both ran reporting no errors, now WTF??? I turn on just a few days later and BSOD's coming out my ass! I am going to go back to square one and reset the BIOS to defaults, reinstall Vista, get my mobo and GPU drivers, go back to the BIOS overclock again, and re-run P95 and Memtest86 v3.5.
Does anyone have any other suggestions or other software to verify stability? Thanks!
This should be your second stop. You need to know something about thermal management or you can fry your CPU. It's actually kind of difficult to fry a modern CPU, but it is possible.

Third stop will be a guide for your particular motherboard. Google is your friend.
