I checked the event log, and the majority of the crashes weren't in there. Most of the time, an error message doesn't even appear. I'm running an AMD Athlon 2700+, 1GB DDR RAM, Radeon 9250 128MB Video Card, Sound Blaster Audigy SE....i don't really think overheating is the problem, the programs run fine up until the exit. I'm at a loss on this one. I re-installed the OS (windows xp pro service pack 2) and updated the drivers....still same problem.
