Complete guess here but try disconnecting your system from any network connection and test for a day...completely offline.
P.S. if you could provide more information that may be usefull. e.g.does the mouse cursor atualy completely freeze along with the system.
BTW I'm a part time comedian. :D

before reformatting the hard drive and starting all over again try getting a spyware program from the net and see what it finds. Its probably not a virus but may be spyware or some keylogger.
