Windows 7: What settings in Device Manager will allow Win7 to 'discover' a card

What settings in Device Manager will allow Win7 to 'discover' a card

The installed driver on this system for onboard video is ATI Radeon 4250.

If a PCIe Nvidia card is installed, can device manager have the ATI Radeon driver
turned off to discover the newly installed NVidia. And from there put in the
needed Nvidia driver.

Also on this, does the NVidia driver install include the NVidia control panel?

Attached is a screen shot of the XFX Video card to install made with Everest.

Looking at this highlight, I got some info from the system I temporarily installed to.

Anyway it's a Geforce 6800

When you installed a graphics card in your PCI-e slot, the onboard should appear disabled and not visible when you boot up your computer (Some motherboards makes it easier for anyone to upgrade a graphics card, just disabling the onboard GPU automatically if they detect a device in the PCI-E). Your computer seems to be alright. Have you installed the drivers for that GeForce 6800? The resolution on the screenshot looks small.

Thanks for answering. I know this duplicates a question I made earlier.
I'm on the right track and located the card manual via a google search. That says
that yes, you should delete the driver in this case the Radeon present on the system in Device Manager.

I had seen this technique earlier when migrating a disk. That it is indeed possible to migrate
a hard disk from one motherboard to another by deleting all but the generic
HD driver. System will then think it's a new install.

The same sort of thing may work for graphic cards and avoid the BSOD.

I could mark this solved. I'm not going to do the operation til needed (at a power down
for whatever reason.)

In most cases, yeah you should uninstall the onboard graphics driver before proceeding into installing the driver of the dedicated graphics card. In some cases, you don't. When you disable the Onboard GPU in the BIOS the driver itself will be hidden and you can proceed installing the drivers for the dedicated ones, usual for pre-built desktops.

I am back and a thing went wrong in this.

What I managed to do was disable the Radeon driver in Device Mgr. Then after shut down and plugging to the card etc, I attempted to get video from the card but all has failed: a dark screen on that HD. I am using a backup HD.

Repair Windows Routine hung at the video. Also cannot get to Safe Mode, the trace of
programs loading stopped at a line I didn't write down (forgot). But it's all the same. Disabling the
video driver did not revert to the Win7 default 640 x 480 or whatever happens when
video discovery is supposed to take place. I'm stumped. Not even explaining it adequately.

As to Repair tools I've never seen Win7 repair anything.

I do not want to have to lose that primary disk. Is there any fix?
