I installed the windows 7 ultimate (before it was windows 7 home premium) now my video card is not functioning?

It said



"Update the driver for your video card"



The current video card may support Aero with a driver that is compliant with the Windows Display Driver Model (WDDM). Contact the manufacturer of your computer or video card for a WDDM-compatible driver.



What to do????

i'm using a laptop model is hp Compaq nc6400.



thanks guys|||That model isn't supported by HP for Win7 Ultimate!



Try the site below and use Vista drivers, they usually work...
