Hey everybody. Perhaps you can help me out. For some reason unknown to me, every time I exit out of a full-screen program, usually a game, my PC freezes like a chump. It might have something to do with the changing of resolutions because I get a black box covering the top-left corner of my screen with my Taskbar at the bottom of it. Nothing responds and I have to do a hard reboot. I'm running an eMachines with an NVidia GeForce 7900 GS.
