I installed windows 2000 over windows 98 and now I have a problem. When I use windows 98. I can run it just fine forever. When I go into windows 2000, I can use it for a while and then all of the sudden computer turns off. Nothing ask for confirmation. Just turns off like someone pulled the power. Could it be my power supply is too low. I removed my cd rom drives and fans and it still does the same thing. Please Help Anyone.
