Try setting it to something else, then back.

From what you're seeing though, it would seem to indicate a very severe driver crash (Vista is better about not totally crashing for most failures), or a hardware issue. First thing to do would be to check the windows event log (unfortunately I don't know where it's at on Vista) and see if it lists any errors at the time of the crash. If you need help finding the error log, support@stardock.com should be able to assist.
