His model can come with either an AMD or Nvidia graphics..
If you can get back into the desktop try and download the drivers displayed on the site. They may appear old but as your using Win 7 try them anyway.
Apologies I thought you had an nvidia set up so from the list choose AMD. I don't see a drop down menu when i use it but hence my question..AMD is the one which appears as default, so should I leave it as such?
