In my experience, if the AMD Athlon has too much voltage (Vcore value),
it would crash even when idle every approximately 15 or 30 minutes.
Or if overclocking and you don't have enough voltage (vcore) ,
Windows would BSOD when playing 3D games and "EXL set/address defined:FALSE"
with Project64. (emu core error)  Windows XP, when running Need For Speed III,
Windows XP was crashing with "STOP" "Driver_IRQ_NOT_LESS_OR_EQUAL" and it
went away after dropping my overclocked AMD Athlon T-Bird 900 from
1050 mhz to 1000 mhz.

Seems like Windows XP is less tolerant of overclocked processors.
