Restart Problem

I have been having a serious problem with my computer lately. When I am playing games for a while the computer will just suddenly restart. It has happened even with a fresh format and install on Windows 2000 and Windows XP Pro. I set windows 2000 to show me the error code with the BSOD and it came up with this...

Driver_IRQL_Not_Less_Or_Equal
STOP 0x000000D1
(0xF0000000, 0X00000002, 0X00000001, 0X85460E4F)

Now I don't know if this is the problem it's been having because it has only done it once and im waiting for it to happen again to verify it. But how would I go about fixing this?

also my -12v reading is at something like -167. something....is this correct? My +12V is fine and running at exactly +12V. I don't know if this is related or not.

Any suggestions will be appreciated! :good:
