Ok, so something happened with my Pc. It had a virus and I couldn't sign in my PC. So I had to reformat the Computer so that everything is gone and that the virus is gone. So it was. It took all my data away. Anyways, when I tried to play games after I have re-installed them they wouldn't work because it says graphics error
So I went and typed dxdiag to see and on display my graphics card details is gone. It said n/a on everything.
How do I get my Pc to read my graphics card when I reformatted the computer???
