* Onboard video and pci video card conflict. Vista

[Kathy]

I was wondering if someone can help me, I have a Presario SR5050nx with
onboard video,

Intel GMA 950 (82945g express chipset) with vga port in the back panel and
the latest drivers,

and the motherboard has 2 pci and 1 pci express x16 and Vista home.

I decided to install an Nvidia PCI FX5200 video card (vga and dvi) and I
would like to have 3

monitors (3 monitors makes things easier for the type of work I do) but once
I install the pci card,

it says "Incompatible display adapter has been disabled" and I can only get
to use either the

onboard video or go to bios and set it to use the pci as primary and use the
pci card (w/2 monitors).

Intel says that it can be done with a pci (no pci express), I don't know
what am I missing. See:

Has anyone got the onboard video and pci video card to work?

Thank you for your help.

Generally, you must disable the on board video system when you want to
use a plug in video card. The multimonitor capability can be gotten from
the right add in video card. (Usually, two to four monitors are
supported by many modern video cards.)

Just because Intel says that something is possible doesn't mean that a
particular motherboard and BIOS have the needed support.

Two dis-similar plug in video cards can have similar problems.
