Problems installing a GF4 PCI on a mobo w/ onboard video

[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.

Disable onboard video in bios and set default startup card as agp, then boot into safemode and see what cards are listed

There's no option to disable onboard video, and I didn't have to do so when I installed it the first time (under WinME). No AGP slot either, and I have the default video in BIOS set to PCI.

How do I boot into safe mode again in XP? F8?

Thanks.

are you sure you checked everywhere in your BIOS? If you hvae onboard video there has to be an option to turn it off. Look in your motherboard manual. Maybe instead of a setting in the BIOS you have to do something physically to disable it (like change a jumper or something).

What kind of mobo is it?

Modern integrated VGA does not, and need not, disable when adding a PCI VGA. Problem is that many NVidia chip based PCI VGA cards don't support multi-VGA setups. The solution is to use other cards, success rate with PCI Radeons (7500 and 9000) is much higher.
