I need some help with my computer. When i play any high graphics game my system crashes or just restarts. Some games are like Halo, Far Cry, and Driver 3. The problem is that the games play for about 5-10 minutes but then my computer restarts or locks up. Why does this happen somebody help. I have a Radeon 9200 SE 128 and a P4 2.8Ghz processor with 512 ram. Could this be some type of overheating problem even though i have 2 fans and a system blower right next to the Graphic card. Could the problem also be with my motherboard because it is kind of cheap as i only got it for $50. It is a PcChips M916 motherboard.
