Hi, i have been working with my Radeon HD 7850 for a while now and haven't had a problem until a few weeks back. A few of my steam games Counter Strike: Global Offensive and Left 4 Dead 2 wouldn't work. I looked around and I felt that it was my graphics card had something wrong with it. I checked and which usually Catalyst Command Center would start up right away wasn't starting up right away. I tried manually starting up and it would say that my display driver wasn't detected and that i couldn't open up Catalyst because of it. Then i tried a re-install with both Beta 12.11 and 12.10 versions. When I re-install at the end when the install is completed it says the installation was incomplete and I click View Log and it says AMD Display Driver and HDMI/DP Audio Driver failed when installed. I tried again but this time using Driver Sweeper and still got the same issue. I made sure i re-installed the new Netframe 4.5 as well to make sure but i already had 4.0 on it already and still didn't work. I finally went to device manager and it said (Code 19) so I rolled the graphics driver back to a point i worked and the games work now but the Catalyst Command Center still won't work. The games work now in the roll but i would rather have it on the current driver and be able to use Catalyst Command Center. My specs are...
Intel i5 3570k
2x4GB Corsair 1600
Radeon HD 7850
Windows 7 Ultimate 64bit
Hopefully this covers everything and hopefully i covered most of the possible solutions that were posted here. Not in much hurry right now.
PS: I tend to update all my drivers and windows update a lot because Battlefield 3 sometimes doesn't work well if not.
