For some reason, over the past 3 weeks, my computer screen is freezing when i am only playing games. Does this mean my graphic card (Geforce4 ti 4200) is on its way out. i cant think what else it could be, i have reinstalled its drivers, reinstalled direct x 9c. Any idears as to what you think could cause this could be, would be appreciated. I dont want to have to reinstall windows to see if this fixes it, if there is somthing else i can try.
