Hello THEO,

I am sorry you are having problems with the driver but let me help you.

Based on the information you have provided I would like to point something very important:

  1. At this point the latest drivers we have available for your graphics controller is for win 7 only. You can check this information at the following link:

If another Operating System is used with this controller, the system can lose functionality or special features due to lack of drivers. My best recommendation is to install a compatible Operating System with the system to make sure all components will be working fine.
