I'm using a Sony VAIO PCG-8V2L right now. And the laptop doesn't seem to recongize my video card is there.
It just has the Generic VGA Graphics Adaptor under Device Manager.
I know it has a Nvidia graphics card because I did the same thing under Vista, only it showed up under Device Manager for Vista, and I just had to update it from there.
I tried going to: Drivers - Download NVIDIA Drivers
and try to run the install, but is just says It can't find Compatible Hardware. I lost the manual for the laptop, so I'm sure on the exact graphics card model, I just know its Nvidia.
I looked at the hardware ID for the "Generic VGA Graphics Adaptor"
not sure if that information helps or not..
