|bamashooter, I'm a little confused about your problem. Does it:|
1. hang for a while and then continue?
2. Freeze totally so the only relief is some sort of drastic action like a restart?
I'm assuming it's #1 and that usually is a memory issue. Your total's sorta borderline. In my experience, XP likes at least 500. Take a look at what you have running in the background and see if there's anything you can edit. If that all seems necessary, add more memory? A momentary 'hang up' is usually just buffering. Think of it as Windows 'clearing it's head'. Aggravating, but usually not too serious a problem.
