DirectX Error on win 7

[gtgunner64]

I'm running a AMD phenom II X4 @3.4 Mhz,8Gb ram, AMD radeon HD 6800 series,  on a Win 7 ultimate white all the latest updates.
Yet when i start up BF4 i get the flowing warning:GPU does not support Direcktx 10.0 which is required.
It makes no sense because i play the game before on the same PC.
Can someone help?
