Well here's the deal, I'm having problems with my Radeon 9800xt (I'm assuming). I'm running a AMD3800+ Liquid cooled, 1024mb corsair xmspro, on an Asus A8v board... I do a fresh install of windows (XP home/pro) and everything goes fine until I start messing with my video card. I install Castalyst 4.9 and my display freezes up... (The mouse only moves right-left and the desktop is kind of scrambled. From then on (after I install the driver) my comp will only boot windows if I set the AGP bus speed to 4x. Even at 4x, if I install any of the newer ATi drivers (i.e. 5.6 /w control center) it does the same thing. Any ideas?? Please help me!! I'm going to upgrade to a dual 6800gt SLI system or at least an X800/850XT, but until then I would like to be able to run HL2 and FarCry @1200x1600 without being choppy...
