Problems with GF4 PCI with onboard video mobo

[Yohhan]

Question for anyone who might be able to help...

I'm trying to install a Geforce4 MX420 PCI onto a motherboard with onboard video. The strange thing is, I was able to successfully install it using windows ME. However, later the card was removed, and the machine reformatted and WinXP installed as the OS. I went back and tried to reinstall the card, and I am able to see the screen as BIOS POSTs, and when the windows XP startup screen comes up, but when XP actually loads, the screen goes black. I can still hear sounds, but nothing shows up on the screen after the initial loading sequence. I found that very strange... does anyone have any suggestions as to what could be causing this? Thanks ahead.

you have to set the PCI video card as primary in XP, even though it set in bios.

Ah. Where can I do that inside XP?

You change this under display properties > settings
