Welcome to the forum, @IxiusDarks 
!
There’s another user that had this bug
But unfortunately, seems that it has no easy fix.
(By the way, do you have Service Pack 1 on your windows 7? I think it isn’t related to the graphics but with starting the game itself, just confirming).
Can you try updating your graphic drivers from your manufacturer’s website? (I think you can manually search for it here: http://support.amd.com/en-us/download there’s a section below that allows you to select your card to search specifically for your graphics card).
