I have just reformatted both of my comp and one of them keeps going into a quick black screen and then back if you try and do something the other half way through a game will go out of the game and back to the desktop. Any ideas !!!
Are you pushing atl+d in the game? That will show the desktop, even the windows key will do that. Also, have you shut sticky keys off? To test push shift about 5 times and if a window pops up, you should turn them off, they can really be a bugger while you are trying to play a game
