Here is the story:
I originally built this system late August with hopes it would be an awesome gaming system. Since day 1 however, it has frozen randomly. It either hard freezes, or abruptly reboots. As of now, there is no overclocking, and the system is set at all defaults.
I have done the following:
* Tried a new, larger power supply
* Ran memtest for almost 24 hours with no problems
* Tried XP and Vista (both 64-bit)
* Removed ALL unused components. Left only video card. Even unplugged CD-ROM drives
* Tried another keyboard (not mouse, but mouse had no problems on previous system)
* Downloaded all of the latest drivers (first thing I did)
When I Prime95 & SuperPi simultaneously, the system freezes. Sometimes instantly, sometimes after 10 minutes. When not running stress test programs, it freezes seemingly completely randomly. I have run Hardware sensors monitor while running stress test software, and CPU temp PEAKS at 53. 72 is supposed to be safe for this proc.
I am ready to throw this out the window... any more suggestions?
Oh, and no weird entries in the error log.
