disable the onboard in the bios 1st,then right underneath that
enable the pci slot for video that should do it.....
Revised * Disable the onboard video in BIOS.
Set primary video to AGP in BIOS. " I hope I'm not way off here"
These steps apply to most newer BIOSes.
With monitor connected to on-board video:
1. Enter ROM BIOS setup.
2. Go to Integrated Peripherals
3. Change Initiate Display First to AGP instead of PCI or Onboard.
4. Reboot with monitor connected to AGP card
