I recently upgraded my comp. to xp (very reluctantly). I did this because a lot of programs are not supporting earlier versions of windows. Since installing xp, my computer is constantly shutting down and restarting by itself. There is no common denominator as to when it shuts down. Anytime, anyplace. Up until yesterday, I never received an error message and then finally lo and behold an error message. I immediately sent it to Microsoft and I got a reply saying "an unknown device driver is causing a stop error". It did not say what driver. Any suggestions.....please.
