I recently installed a new harddrive as C:// and reinstalled steam and all my steam games, just that, Black ops 2 won't launch, when I press Play it says on my friendmenu that I'm "in-game" but nothing appears on my screen, no error message, no blackscreen, nothing, as it wasn't there, not even an icon on the bar at the bottom of the screen that indicates it's started, I have to open up Windows Task Manager > processes > end process to shut it down.
I think it's my graphics card driver, got ATI Radeon 5800 HD series and latest Catalyst driver, notice that when I installed my new harddrive I had to reinstall all the drivers etc. I have checked everywhere for answers, but all I could find are scenarios where there includes a black screen etc.
specs
intel core i7 3.20ghz
ATI Radeon 5800 HD series
9GB ram
SSD harddrive as C:
Please help!
