I don't know if this is in the right section, so i apologize if it is. I week ago I was running Orange box fine on Windows 7 home premium via Parallels desktop 5, but I decided I wanted to reinstall Windows 7 on bootcamp for a better performance. Windows 7 and the Orange box installed fine, but when I tried to play half-life 2 the valve logo movie thing would play but after that a white screen would appear and it would just close. I tried the other half life games, TF2, and portal and they would all not start. Can someone please help me?
