Correct. Driver sweeper is free. Uninstall your display drivers from the control panel. Run Driver Sweeper and delete the rest of your display drivers. Boot in safe mode and delete them again to make sure they are all gone.
Then download and install the latest drivers from Nvidia's website.
Always download the latest drivers from Nvidia's site because the manufactures don't update their driver section as often as Nvidia.
However there is no need ton use driver sweeper twice, after you uninstalled your drivers from control panel, boot to safe mode and use driver sweeper to clean whats left.
