All the recent games out there like the splinter cell chaos theory, everquest 2, and others when they start up. the intro screens are fine but when it gets in game, before it runs it restarts my computer. I have low specs but whats going on? my specs are 1.3 ghz amd athlon and 320megs of ram. nvidia geforceFX 5200. I have all the updated drivers for everything. how can I fix this? any ideas?
