Help with Windows 7 showing "Standard VGA Graphics Adapter"

This here is the problem. I have switchable graphics. I tried uninstalling the drivers and reinstalling them but the AMD ones will not work AT ALL. I have tried so many downloads for that gfx card on AMDs site. If I uninstall it and reboot it automatically reinstalls. It will not let me choose drivers because windows says the best drivers are installed. How can I get it to recognize my ATI Radeon 6490M rather than a standard vga graphics adapter?
