Have you added RAM?

Big subject:( What OS. Try subject site:sitedotcom in google for a tech site or fav fixit/utilities site like kellys-korner. eg hibernate problem site:microsoftdotcom. It could be any number of things from graphics card related to a resetting in Vista.

I have Windows XP sp2 and no I have not added any RAM. Hibernation IS turned on.

Judging from your signature, there might be a security application that started acting up. You might want to check all the applications that download updates; those are usually the culprit.
