I'm running Windows 2000 on my computer. I upgraded from 98 and I couldn't be happier. The one minor problem I've experienced is that about a third of the time I try to shut down the computer, it restarts instead. Anyone know why this happens and how I can fix it? Oh yeah and while I'm on the subject, sometimes when I'm playing GTA3 the computer will suddenly and randomly restart. It's maddening!
