I have a problem upgrading my Nvidia display driver from version 100.65 to 101.41: I have a 7950 GX2 and the 100.65 dirver only recognizes one of the two GPUs.

So I downloaded the 101.41 drivers from Nvidia. I closed my anti-virus software, uninstalled the old driver and installed the new ones. The problem is that under device manager, both GPUs show up but one has a yellow exclamation mark. That is actually the one running (or trying to) the new 101.41 driver, the other one still runs the 100.65 driver.

When I press the update driver button the system updates the driver with the result that both GPUs are back to 100.65 and still only one GPU actually works.

Also, I noticed that while I uninstalled the old drivers using "Programs and Features" from the control panel, they are still installed. I have no idea how to actually remove them correctly from the system. Maybe that is the problem?

Any help?

If you extract the new drivers to a folder of your choice... you can then 'Update driver' and choose the 101.41 driver to be used manually. Have you tried that? (Device mangaer -> Display Adapters -> NVIDIA GeForce 7950 GX2 -> Properties -> Driver update -> Browse my computer for driver software -> Then select the folder with the driver you want.

Once they are both up to 101.41, tell us if it sorts the problem or not

I'm not sure, actually. The system updated the driver to 101.41 but it only shows one 'line' in the device manager. I think it should still show both GPUs, no?

If it is one card it will show 1 product... if you have SLI then it should show 2 I believe.

The issue could be the motherboard. You can run two GeForce 7950 GX2 cards in SLI mode, but your motherboard must be SLI-certified. You might also try updating to the latest BIOS.

The 7950 GX2 has two GPUs on a single card; it's not 2 separate cards in SLI. In XP it has 2 entries in the device manager.

I checked with Nvidia... and in their current drivers only 1 of the GPUs is active and working... they plan to update the driver within the next month to include both GPUs apparantly.

You may want to email them

The 101.41 drivers are still in beta, but should support both GPUs according to this update.

Hmmm... well if they are the drivers you are using, maybe you should contact them to see if it should show both GPUs? They are usually very good at replying.
