ive been trying to install the latest drive 186.18 to my pc but it refuses to budge in. Anyone with any clues to why?

p/s: it does read in gpu-z with correct ver when installed but i cant seem to get to my advanced tab button in the control panel. Some error keeps poping out which i cant recall what it was rite now.

ive done uninstall the std 181.21 driver and physx. However did not uninstall rivatuner. Could this be the problem? or is it just the driver itself and i should just download an earlier version and try?
