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.
