I have had a dell inspiron desktop with an AMD 7770 for a while now. I upgraded to windows 10 as soon as it was available. It worked fine for the first month or so, but now the graphics card is not working at all. I am using the integrated graphics card for now. When I go to device manager there is no AMD graphics card there, but when I check, show hidden drivers, it appears but is greyed out. From everything I can find the card is compatible. I have tried uninstalling and reinstalling the drivers for the AMD website (I have also tried installing the catalyst). I have also tried going into the bios, taking the graphics card in and out of the machine and a few other things but nothing worked.
I would greatly appreciate any help.
