I had the same problem here with a system.  Turned out to be the kb840987
patch.  I removed it by booting into Safe Mode and using Add/Remove programs
to remove the patch.  In my case, there was another patch applied after it
(841533) that I had to remove first.  After removing the patch, my system
booted up fine.
