I have an Asus A44H laptop with a AMD Radeon HD 6470M.
When I'm trying to install the graphics driver, it says that my computer does not contain a proper graphics adapter.
Make sure you chose the Notebook drivers.
64 Bit Win 7/Vista
try this ones here:
just be sure to choose the right ones, that is, the MOBILITY version, and either 32 or 64 bit version.
hope it helps, those worked for me in a win 8 (updated from 7) HP dv6-6c85la with a radeon hd 6770m (hp names it as a 7690m xt)
