Hi. I have a Toshiba computer with Windows 7. The processor is AMD Anthlon. Whenever I play certain computer games on this computer, there are black bars on the sides that make the game screen really small. Is there a way to get rid of these black bars? I used to have a Compaq with Vista and none of the games I played had these black bars. So if anyone could help me, I'd really appreciate it. Thank you.
