Can't install new video card over onboard

May 12, 2009 at 22:33:45
Specs: Windows XP
My system runs on an nvidia nForce6100-430 motherboard, which includes onboard video. Until recently, I had installed a Radeon video card, and left the onboard video alone. However, after upgrading to an Nvidia GeForce GTS 250, I cannot get the system to install the new card. The install disc runs, and updates the drivers for the onboard (if the onboard is disabled, it also enables it) without installing the drivers for the new card.

Manually installing the driver has been no help either, since every link leads me back to the same nvidia software package, 185.85. What can I do?

"I had installed a Radeon video card, and left the onboard video alone"

What do you mean you left it alone? When you install a card, you should disable the onboard in the BIOS. There are several different settings that may need to be addressed...enable/disable, shared memory, Initial display 1st, etc. Each BIOS is a little different. You *should* have done that before you installed the ATI card (whenever that was).

Now that you're changing cards, the 1st thing you should have done was uninstall the ATI drivers. Then you should have shutdown & swapped cards. On the reboot, the new nVidia card should have been detected & you would have been prompted for the drivers. I just had a look at the nVidia site & v185.85 is the latest version available. What makes you think the onboard is being re-enabled?

The very first thing I did was remove all the ati software. I disabled the onboard card in device manager, and set the bios to pci-e. Started up with the monitor connected to the new card, recieved no signal at all. Started up with the monitor connected to the onboard card, loaded windows, onboard card was still disabled in both device manager and bios. Ran the nvidia driver package (185.85), it completed "successfully". When I went back to device manager, the onboard had been re-enabled.

"I disabled the onboard card in device manager"

reread Jams post;
you should have disabled it in the bios, its defaulting back to the onboard vga because you havnt 'switched it off in the bios.
and set to enable pcie.

Does the new card require power to be connected to the card? and is it plugged in?
