Problem with onboard versus Nvidia video card

[riddellcomp]

Okay Im having problems with a computer I have that has onboard video and a NVidia video card.

Here are the specs.

Celeron 1000mhz

128mRAM

MS-6368 motherboard with Trident video accelarator Blade 3D/promedia 8mb

NVIDIA GE Force MX 440 vid card.

The problem I have is that I cannot disable the onboard video card via the BIOS or via jumpers. In the Display settings both video cards are shown as if there are two monitors connected. They are setup as
1. default monitor on trident video accel...... and
2. Plug nplay montior on Nvidia......

If I disable or uninstall the onboard vid card in the device manager and connect the monitor lead to the Nvidia vga port two things happen. Firstly on reboot I cannot see any of the display until Windows has started to load and the Welcome screen is showing. Secondly when the computer finshes booting I get a blank desktop with no icons or mouse just the background wallpaper. And the onboard vid card re-installs itself.

Okay so then I swap the lead back to the the onboard vga port. Change the monitors around in the display settings so that the Nvidia is the default and then re-boot with the lead plugged back into the Nvidia card. This fixes the problem and I am now able to see the icons etc However I still cannot see anything on the screen until Windows gets to the welcome screen. Im assuming this is becuase the onboard card is still enabled.

Any ideas how to fix this???

There is no way to disable the onboard video on an MS-6368, so yes, if you uninstall its drivers, they will just be reinstalled again.

Do you only want to run the one monitor on the nVidia card? If so, have you set "Initialise display first to AGP" in the Integrated features section of the BIOS setup?

[riddellcomp]

Thanks Platypus, that did the trick. Although there is no AGP slot so I changed it to "Initialise display first to PCI".

It works fine now.

[Platypus]

Curious, the AGP setting was in the BIOS options listing for the MS-6368...

Anyhow, glad it's sorted out!

[riddellcomp]

Whats even more strange is that it was already set as "Initialise display first to AGP" even though there is no AGP slot. (I just double checked as the cover is still off.)

[Platypus]

Ahh OK, it's got AGP, just no slot...

I was wondering if there were two models, one with & one without, but I should have realised the on-board was probably AGP and if it couldn't be shut down there'd be no external AGP slot.

Probably a bit late to be thinking clearly...

What are you doing up so late on a Sunday night? Its midnight over there now isnt it?

[Platypus]

After midnight, I keep late hours.

From my understanding the agp is the onboard video

Yes, that's correct. As riddellcomp didn't specify in his original post that he was fitting a PCI card, it seemed likely he was putting in an AGP card to take over from slower PCI onboard video. As it turns out, the onboard is AGP, but can't be disabled, so the secondary video has to be PCI.
