Is Fairuse4WM causing my comp. to automatically restart?

I’ve gotten a lot of good info from some of you guys, and I hope someone can help me on this one: I have a 3-year-old Gateway notebook, Windows XP. Recently, I installed Napster and Fairuse4WM. Since I installed Fairuse4WM, my notebook will sometimes have a blue error screen with words on it and then it automatically restarts before I get a chance to read those words. The Notebook starts up fine after the shutdown, but, obviously, the whole “autmatically restarting thing without provocation” is very irritating. This never happened before I installed Fairuse4WM, so I’m wondering if that has something to do with it. Anyone here know the problem? Thanks a bunch…
