Hi, I have some problems with the Radeon 9800 Pro i just bought. After installation, it seemed to run ok, but when i started a game (Prince of Persia 2), bad pixels started to show up on screen. After i quit the game, there are bad pixels all over the desktop. I have a Dell Dimension 4500 CPU: 2.0G RAM: 512M 4x AGP Could that be a over-heating problem? Please help. thx.
