I am running windows XP and I have a Radeon 64 M DDR vid card. My computer is frequently locking up. The screen will normally turn multicolors running horizontally along the screen. Sometimes it will just turn black however. Sometimes when it happens and I restart XP will come back with an error message saying the Radeon drivers weren't able to complete the last drawing operations or somethin along those lines. This once happened before. I remedied it by cleaning up the card. I tried so this time but no such luck. I have no idea what else to try. It has gotten so bad that if I leave the computer idle when I come back there isn't a chance in the world that it will wake up due to freezing while I am away. Does anyone have any suggestions? Thanks!!
