BSOD during games, driver_irql_not_less_or_equal (minidump)

Hello

I am having BSODs playing 3d games such as Hitman Blood Money or Splinter Cell. I ran memtest for a few passes, no problem. I ran Prime95 stress test, no problem.

I built this a few days ago:
ECS C19-A SLI mobo
ThermalTake 430W PSU
1 stick, 1GB DDR2 667 RAM
Pentium D805
EVGA 7600GT
1 SATA hd, 1 IDE

I have not seen my CPU temp go over 55c. My 12v is at 11.78v at lowest recorded. Why does it say DRIVER IRQL error yet this only crashes during games?

Here's my minidumps
