I was posting something earlier and my computer totally froze up. No big deal, right? So I turned it off and turned it back on and kept getting messages about some Windows configuration was corrupted and it promted me to to a system recovery. Some of my stuff has disappeared, but overall things seem to be okay.

Does anyone have any idea what would cause a freeze up that serious? I'd like to avoid that happening again. This computer is only about 2 years old.
