Windows 8.1 Update, HP Pavilion g6-2300sy, AMD RADEON HD 7670m problem.

Hi!
First I want to say that I have read about 70% of posts which include the same context.
So 16.05.2014 ~05.00  I shut down my laptop, there were "windows update" screen. So 17.05.2014 I woke up, Start my laptop and suddenly I noticed that I couldn't change brightness anymore. Then I tried to watch movie from internet but it was so laggy and buffering (I have good connection). So I started to look for that update after a while I found out that Right click - Configure switchable graphics, has been disappeared. Thought it was just something with drivers, so I updated drivers. Nothing. Now Im quite messed up. I cant find the problem and solve it. Nothing from AMD or HP support works (drivers etc).  in Device Manager I have yellow triangles infront of graphics devices. Also it says "AMD HD 7600m" my laptop has Intel HD4000 and AMD HD RADEON 7670M.
So the problem is that I cant do anything with this laptop anymore, because graphics does not work. I have tried 100 different ways to solve this, I have gathered information from different forums etc. So Is there any one who can help me with this?   AMD catalyst not working, Switchable graphics disappeared, no graphics devices recognized. 
Looking for your help guys!
