I have a Dell Inspirtion 8200. When I first boot up my computer I have a small Dell Welcome Screen Popup and a Large Black Box Around the rest of the screen. My actual Desktop Screen is the same way unless I change the screen resolution to 1600 by 1200. Even when I play games it still does the same thing it puts the games into that small box even when I choose full screen. My computer did not use to do this. Can anyone please help??
