I am having problems playing games such as unreal tournament 2003, return to castle wolfenstein or actually anything. When I first downloaded the game demo everything was fine when I played. Now the game will come up and as soon as I hit a key, it snaps back to the windows screen and reboots because of a fatal error. I have the latest drivers for my video card and also the games worked for a while. What could be causing this? I am starting to hate XP more and more. Thanks
