I have the same problem, if I start up limewire, I have to leave it totally alone or my computer freezes up. So if I try to read my e-mail, preview a file, or play a game, my comp instantly freezes.

However, I'm curious as to whats causing it, since my comp seems to randomly freeze up every few hours whether or not I'm using limewire. Its only the extreme reproducability of limewire that led me to these forums.

I'm planning to reformat very soon, but hearing that reinstalling windows didn't fix the problem for many is very discouraging.

pentium 4 3.0ghz w/ radeon 9800 pro
running Windows XP Pro w/ service pack 2

This has been happening for a couple months now. The only thing I changed was my mouse, and I have tried uninstalling and reverting back to an old mouse and it will still freeze consistantly.
