You need to disable the onboard VGA in the BIOS settings.

I tried many thing in the BIOS but says that the videocard is unavailable.and when I install the driver AMD ATI for the videocard says warning occurred during installation.,view log for details .Do the Bios need to be on PCI ,VGA or P ?

 

[Mousemonkey]

Go for P and if that don't work then try PCI.
