If this doesnt work ,Are you installing the drivers via Restricted driver manager ? Try the manual install of drivers - it will remove all existing drivers and install again. To install manually, get the .run file of the driver from nvidia's site. you will need kernel-header and kernel-sources as well.
Copy the .run file to your home directory. Open the terminal, switch to console mode by typing
and once in console login, switch to your home directory, exec the run file using
Code:
sudo sh <name-of-run-file>
