HP Pavilion G6 Display :: Can't Install AMD Driver Properly Lost All CCC Options And 3D

I have HP pavilion g6 , win 7 64 bit. Amd Radeon HD 7400M series and Intel HD graphics.My problem started when my screen was getting  black for seconds  alot and when it comes back it said amd stopped so I decided to update the driver. First I downloaded the supported driver from the site URL.... but every time I try installing it the install process run very quickly the screen doesn't even switch during installation and it says driver is successfully installed although nothing was installed and nothing absolutely change.so I decided to download the latest amd driver from amd site14.4. I had some problems while installing but it worked fine and  I had all the options including the switchable graphics.

But after a while the laptop started to hang on startup showing a blue screen saying something was incompatible.So I tried to update the driver from device manager and since then I lost all catalyst control center options also the switchable graphics mode and 3D in Photoshop isn't working anymore and every time I close the catalyst a message come saying it stopped working. I tried many times to uninstall the driver then installing a new versin 14.9, the previous 14.4, the supported but still nothing of them worked at all, also I tried installing with win 7 compatibility but it always gets stuck.
