I have an Alienware M14x R1 laptop with the 3 GB GeForce GT 555M graphics card. The laptop is a quad-boot system with Windows 8, 7, Vista, and Ubuntu. The GPU works perfectly fine on all the OS's except for Windows Vista. I just recently install Windows Vista Ultimate 64-bit and while I got the Intel HD Graphics to work, the nVidia GPU just shows up as a "Standard VGA Graphics Adapter". I tried downloading the nVidia GeForce drivers, however when I run the installer, it says no compatible graphics hardware could be found even though I'm use the correct driver. Is there a reason why Vista can't detect the GeForce graphics card but all the other OS's can? If so, how can I fix it?

I have the same problem except that my graphics card is ATI mobility radeon hd 6650M ... I installed Windows Vista Ultimate x64 and now my graphics card is not recognized by the OS. Have you fixed it yet?

Unfortunately I still have not figured out the problem. The NVidia GPU just shows up in device manager as an unknown display adapter. For some reason, NVidia's driver installer doesn't see or recognize the graphics card even though Windows Vista x64 is fully supported and my version is fully up to date. I have no idea what to do anymore so for now when I use windows vista, I have no choice but to use the Intel HD Graphics which is ok for most of my needs in Windows Vista. I'll keep looking into this more though and hopefully someone else might have a solution eventually.
