I've tried to avoid you having to do a repair install, but that looks like the next step.
Repair install is almost as bad as complete new install.
That repair install is going to reset/restore much to the same state as before one made all of their own little changes here and there.
In the tutorials here, there is advice on how to perform a repair install.
About the last things left to try before punting to a repair install is to check and make sure there isn't a bios update for your laptop and then after that making sure that you have installed ALL critical, ALL important, and ALL optional updates (except for those thirty some-odd language "updates").
