Windows 11 does not detect my Nvidia graphics card

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.

    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.

    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.

    Do you have this GPU Mode widget on your home page for Armory Crate? You can do the power mode switching there and don't need to go to Devices>GPU Mode. It might be on another page, look below the widgets move to another page.
