I just bought an ATI radeon 9600 Series, I installed it and installed the newest drivers for it from the ati site, along with Catalyst Control Panel. Whenever I try playing Doom 3, I load it up, and it plays for about 1/2 second, and the screen turns a bunch of different colors and it freezes. I try playing Half-Life 2, it works okay for the most part, but there are all kinds or weird colors and lines all over the screen. I tried Halo, and whenever I start it up, it says "A problem occur initializing Direct3D" and it say to check if Hardware accerelation is disabled in DXDIAG. I checked, and it is not disabled. I haven't even tried all my games yet, but I have having a really low success rate, only a couple work good. What should I do?
