My computer was downloading an automatic update to my virus software, when it
froze up.  I rebooted the computer but now it won't properly load windows.  
It goes through all the preliminaries, but after the little windows jingle
plays, all I get is a blank screen with a cursor.  ...

HELP

rid of it with little luck apparently he then tried System Restore but
the system wouldn't let him choose a date...just today's date how do
