I have a pentium 4 2.8 and it has 512 ram. My graphic card is a radeon 9200 se and it has been giving me problems. When i Play a high graphics game, my computer freezes and gives me an ati error. i send the report but get no response. The error i get is that the graphic card has been reset to default. Why does my graphic card freeze. I also think something might overheat because in cool conditions when the room is cool the games work a lot longer. The games freeze after a while like 5-10 minutes. Halo works for about 60 seconds even in the menu. Please help.
