Radeon GPU is not working after update to Win 10

Hi All,

 

After update to Win 10 64bit I cannot use Radeon HD 6770m graphic card anymore (before I had Win 7 64bit). My coputer is HP Pavilion DV6 6150ew.

I tried to reinstall drivers of both cards many times and it's not helping. I have the latest one right now. Before install new one, system was clinned with CCliner and Driver Sweeper.

 

3D Mark inform me:

"3DMark 11 has found DirectX 11 system files, but your graphics adapter reports that it supports only Direct X 10_1.

3DMark 11 requires both DirectX 11 system files and DirectX 11 capable hardware to run. If you are certain that you have DirectX 11 hardware present, there may be a problem with your video drivers. See 3DMark 11 FAQ for more information."

 

So it seems that 3D Mark not even see my AMD card.

 

The same with other programs:

 

dxdiag shows only Intel graphic.

 

In games options (Civilization VI) I can choose only Intel graphic and it's too low.

 

 

PLEASE HELP, what can I do?
