You guys rock! Thanks for all the responses! I've tried most of them but there are a couple that I'm still working on. I'm starting to believe that is a power supply problem, I recently had a power supply go out on me so I bought a new one but I bet the one I got is not that good (AG is the brand

never heard of them) and it is causing problems, maybe inconsistant power like Skligmund suggested. The reason why I think it is the power supply is because come to think of it now the problem started occuring after I put the new one in. It could also be a problem with cpu over heating but I checked all the fans and they all seem to be working. I don't have a temp gauge on the system other then the Bios cpu temp reading but it seems to be fine if I look at it right away after the computer freezes and I reboot. I guess it could be cooling down some before I reboot and look at it but probably not cooling down that much that fast. I might try the suggestion to turn the multiplyer down but that hurts performance and FS9 is a cpu hog.
The really frustrating thing about this is that it doesn't have a pattern... meaning that it doesn't crash at certain times or when doing certain things. Sometimes it crashes right away on takeoff and sometimes it crahes midway through the flight or when landing :'(. I can fly every now and then and it doesn't crash at all but not very often. I do know that it only crashes when playing FS9 and not any of the other games and simulators I play, which Half-Life 2 is pretty demanding and it doesn't crash when playing that and I play it sometimes for 2 to 3 hours straight.
Anyways, you all have been a big help! Thanks! Oh and Moach if the reformatting fixes the problem let me know.
Thanks again,
Todd
