So far this is what I have found. Try tapping F8 at startup, and from the list of startup selections, select Safe Mode by using UP Arrow Key to go there > then hit Enter.
Try a System Restore once there, to pick a Restore Point before your problem..
Click Start > Programs > Accessories > System Tools > System Restore > pick a different time > Next > etc
