I held off for ages installing SP3 but after i installed ACT, my system got mucked up and I reinstalled windows xp overtop and did the sp3 update. This all went smoothly and everything went well- until i played a game like bioshock, MOH or Call of Duty. The games all start then suddenly quit. Bioshock does start but the images are mostly unintelligable.
So far I have...
* uninstalled and installed the latest graphics drivers
* done all Windows updates
* ran sfc
I dont wanna wipe and reinstall.
