Windows 11 does not detect my Nvidia graphics card

Anonymous

Hi,

I have been using Windows 11 for quite some time, Suddenly one day I see my secondary Nvidia graphics card is not detected. Its not displayed in Device manager (even if I select "show hidden devices").

Also, in device manager below System component is showing error code 10.

intel pcie controller x16 1901

I tried reinstalling graphics card driver. Driver reinstallation does not detect my Nvidia graphics card.

I tried updating driver for above PCIe controller. But is already up to date.

I have not changed anything in BIOS. I tried defaulting the Bios values but dint work. ( My Nvidia card is detected in BIOS, only windows 11 has problem)

I tried backing out recent windows updates, dint work. I again updated all latest updates and optional driver updates suggested, dint work.

Since the card is detected in Bios, I am assuming its not an issue with hardware.

I have been doing some research, and in many places I see the PCIe controller issue associated with detection of graphics card.

Please help me resolve this issue.

Tracey,

Sincerely appreciate your trying to help here. I simply don't see a GPU widget. Here's the extent of my homepage:

I did. Here's what I get...

Perhaps I need to re-download the full version (this is lite), but as I recall, I get the same interface w/ the full version.

Huh, that's really all there is? It would surprise me if that is even the full lite version, it doesn't look it does much of anything. I think it's probably a good idea to uninstall it with Asus' uninstaller (Armoury Crate FAQ) and then do a clean reinstall. You'll have to figure out if you can install the full or lite version for your system.

I'd send you over to r/Asus on Reddit, people there have also encoutered this same missing Nvidia card issue, but they hate Armoury Crate and will tell you to uninstall and then reinstall a third pary program G-Helper which will still allow you to do the power mode switching to get your system to recognize your dGPU. But maybe G-Helper will work better for your computer. I think people there have suggested other ways of fixing this issue, so it might be worth checking it out. If you can't find help in r/Asus there might be a sub-Reddit for your particular computer.

The missing graphics card happened to me the first week I had my Asus Zephyrus M16 2023. I was convinced my dGPU had failed, but I kept searching on Google for answer's and finally stumbed on this thread and Roberto's solution. I still can't believe it fixed it. I know now it happened because I tried to play a game which required my dGPU when the laptop wasn't plugged in *and* my power mode was set to Optimized. I just use Standard now and don't have any issues.

Thank so much for these steps. I realized it this morning, with no idea how long it had been like that. I spent just about all day trying to figure out if it was fixable. This saved me so much trouble. Leave it to power saving settings to consistently screw things up. I haven't had this much trouble with power saving settings, since my laptop decided it stopped recognizing my external drive after a few minutes of inactivity.
