Hello Varian Anora

Although it is strongly suggested that you get the latest driver for any of your hardware device from the vendor's official website, if something goes wrong and the downloaded drivers are not supported on your PC, you can try using any of the available third-party driver detecting programs.

A few such programs are:


  • DriverPack Solution
    Device Doctor, etc.
Hope this helps.

For laptops, you want to use the driver from the laptop vendor, not from the chip maker. Get the drivers from ASUS, or contact them for support. Although since you installed your own (likely pirated since it's Ultimate) version, they won't help you.

Try uninstalling all nvidia drivers, PhysX and GeForce Experience and try installing the ones available from ASUS
