Try to install CUDA Toolkit (https://developer.nvidia.com/cuda-downloads), see from their FAQ: *Q: *Will the installer replace the driver currently installed on my system? *A: *The installer will provide an option to install the included driver, and if selected, it will replace the driver currently on your system.
