I've got a new computer on the way that I got from someone else cheap because he doesn't know to much about computers and couldn't figure out how to fix it. What happens is the computer boots and goes into win98 fine then it just reboots after a varied time 5 mins, 10 mins always a different amount of time. Its apparently not the cpu hs and fan as he checked that and reset it with new grease. I have a few ideas of what to check but it never hurts to hear what others think the problem could be. So if you've had this kind of problem or have any guesses lets hear them.
