Another option (last resort):
1. copy all your important data, passwords etc to a backup drive
2. RESTORE the original Windows (should be on a hidden partition and you restore it by pressing the proper F-KEY during bootup).
3. Apply all the updates. (video driver, main chipset etc must be obtained from your laptop's driver support page)
4. create a BACKUP IMAGE in case this happens again (Acronis True Image preferred). Keep the first backup after all updates forever, then keep a second backup to replace periodically with a new backup. The first backup is kept because you know it's not corrupted. You do have the original (hidden) copy on the hard drive but updating (especially the drivers) can be a lot of work.
