My graphic card doesn't work as it should.

I just got back to Windows 7 Ultimate from Windows 8.
I instantly downloaded World of Warcraft and League of Legends, and i have problems opening both.
When i open League of Legends i get the message: could not load direct3d.
And when i open World of Warcraft i get the message: Failed to find a suitable display device. Exiting program.
I guess its some problem with the graphic card atleast.

DxDiag: dxdiag - Pastebin.com

hi,

please post your pc specs...

If I understand the DXDiag listing correctly, you need to download and install drivers for your AMD Radeon 5700 series card. www.amd.com.

Go get the latest version of directx updates regardless of your directx version Download DirectX End-User Runtime from Official Microsoft Download Center
