@Micheal_Schwarz - thanks for the advice, i will try putting in my old Geforce 7300

@TriNitroToluene - I'll try that, the games don't really crash though...they just go really slow

@Broozar - Whats wrong with XFX? lol

I was thinking, if it was the video card over-heating, would it stop displaying on the monitor?

Thanks, Doof
