Hi i may have found the solution to your problem, on the same site i got my driver and such i searched your card and found a file that suits your needs.
go to this site http://driverscollection.com/? and click search. AMD Radeon HD 7650M search for your card as i have listed from you into the simple search bar and search. You should see different drivers for different platforms and since you said you upgraded to 8.1 the first options should suit you, but make sure you read through them to see which exactly you need. I hope this helps you as it did me.
What i did was to just install the file and everything was back to normal, this was after i uninstalled my driver from the device manager and my display adapter tab disappeared completely, after the above everything was back to normal.
