I have updated the bios (A11 -> A13) and formatted my notebook and installed win7. 

Now when I try to install Intel Graphics driver, i get this message "this computer does not meet the minimum requirements for installing the software", and the driver won´t install .

When i install amd driver ( Dell AMD Radeon HD HD7650 (WhistlerLP); AMD Radeon HD7450 (SeymourXT) ), it install both graphics card (intel and amd) but i can´t switch to amd gpu. I have selected on catalyst to choose de graphic card by power. When i select intel graphic and run gpu-z it only show me one card, when i select amd gpu and run gpu-z it show two graphics card, but the system use intel card (i´m getting low fps in games)

Somebody can help me.

Sorry my poor english
