When playing COD4 and running RAH I somehow loose my video signal after about an hour, and the system reboots itself after a minute or two. It has never done this before, and it still does it on a reduced overclock. Even when running FAH and playing COD4, it was fine.Any suggestions?
I have also noticed my event viewer is filled with 'Kernel-Processor-Power' errors, although I never looked to see if they were they before. I have speedstep and alike turned off.
Cheers

4 cores certainly helps the points go up quickly
