Add FX5500 Card to Acer Veriton 5800

[abrogard]

I want to add this PCI FX5500 card to an Acer Veriton 5800.

The computer is running Win7 (unregistered)

I put it in and loaded up drivers.

Device manager sees the card and reports it is working alright.

But I get no output from it. The onboard graphics continue to work.

I can find no way to disable one and enable the other.

What's the way I should be doing this? Anyone happen to know?

Have you tried disabling the onboard video in the BIOS? A pre-built PC's desktop should have that option.
