In Safe Mode (with networking, to update).
He said not all of his windows are blank.
Absent his replies, we cannot help any further. But next I would use a bootable AV CD scan: http://www.techmixer.com/free-bootab...download-list/
If you regain functionality, then follow steps given earlier to run System File Checker or a Repair Install, or if neccesary Malwarebytes from Safe Mode.
Next I would boot the DVD Repair console or Repair CD to run Startup Repair, which should offer System Restore. If not, run System Restore from the Recovery Tools list.
