ok ever since i installed my new coolermaster aero 7 lite hsf, my pc been crashing when i play games. i even reformatted. and it still crashes.
here are my pc specs

its probably power related ?
and the cpu temps are 30c idle 37c under load
mobo around 35c the most
drivers im using now cat 4.1 via 4.51 and directx9.0b
4x agp.
and i got a new hsf because my old one died out. it was a dynatron dc1206bm-l/610-p-cu.

I think it's a motherboard problem.
