Restore Points are for if you have problems. Like if you accidently change a configuration and you cant undo it. The PC will basically recreate your computer as it was on the date of that Restore Point. So technically, it will recreate your PC with the drivers. I hope so anyway.

If you do this, make sure anything important saved you might have on your comp between now and the restore point is backed up otherwise you'll lose it.
Hope this helps.
