1. Did you slide the 'hardware accelleration' slider all way?
2. All tests by Start>Run>dxdiag OK?

Dell Dimension 4550 2.5 ghz, 781mb ram, win xp home sp2, ati raedon agp 9550 256mb. When playing games they minimize and return me to my desktop. I have tried adjusting video settings for card, adjusted in game video settings but neither seem to work. I updated video drivers thinking this could be causing the problem, but still the same. Does anyone have any ideas.
