Since a few weeks i've got this problem :whenever i try to launch any game, i've got a message such as "Directx failed to iniztialize Direct3d, make sure your drivers are up to date..." .
My games worked pefectly 10min before. I don't see what could lead to this problem.. The only solution i've found so far is to reboot and then it works fine agian for a few times (1h, sometimes 6) it seems to be random.
I'm using windows 7,directX 11, my gpu : AMD Radeon HD 6900 Series , catalyst 15.7.1
I've tried to uninstall and re-install my drivers but it doesn't changed anything
Some help to fix my problem would be great !
