Have you ever updated, or installed a Driver for your Graphics Card?
Go to your Computer Manufacturer or Motherboard or Graphics Card's
Manufacturer's website, and download and install the correct, Vista
compatible Driver for your Graphics Card, or onboard Graphics.
Hi!! I've heard compatibility is a key issue with the graphics card. I've also heard people have had weird problems with resolution. Someone swapped the DVI Cable for a D-Sub Analog Cable with a DVI-/D Sub Adapter at the GPU. Then booted into Windows in VGA - enabled mode. Which corrected the problem, but the picture was off to the side. This person then went into the NVIDIA Driver control center and created a custom configuration which addressed resolution, refresh rate and color depth. That did the trick. Sincerely, Celestra
