I just got a new video card (Radeon 5770) and installed it on Windows XP. However, when I try to change the resolution it doesn't actually change. I can move the slider, the screen flickers and asks "do you want to keep this new setting?" but nothing actually changes. Also, I can change the resolution via the catalyst control center but when I alt-tab or exit from games (which work fine) the resolution resets again to 800x600. Also when I reboot it resets again to 800x600. I've tried both 10.9 and 10.8 drivers and the same thing happens.

Maybe if you do a repair install of windows it will fix the problem.
