I have a Dell 1525 which I reinstalled xp on recently due to a hard disk problem.
Apparently I've missed something, it's taken to restarting for no apparent reason (I believe it's too frequent for windows updates which was my first thought).
Last night it was particularly bad, it stopped 5 times in 2 hours while playing an online game. I can't actually think of a time it's happened when it's not running something in full screen mode.
I can't see anything in the event log apart from usual start up details. How can I find and fix this issue?
