Do you have the video card's power supply connected? Are the power connectors tight at both ends? Slot power alone might "light up" a video card without giving it enough power to actually work.

 

Just reseated both ends of the cable. I even plugged in the cable to a different slot on the power supply and still no luck.

 

What is the Make and Model # of the Motherboard?

When a GPU is installed, most motherboards disable the Integrated Graphics.

Boot into Setup (Bios) Go to Advanced or Integrated Peripherals. Look for Onboard Video or somesuch. Is your nVidia card listed? If so, Disable the Onboard Video/Integrated Graphics. Save and Exit.
If you see the motherboard Splash screen while the monitor is plugged into the Video Card you are half way there.
Then download the latest driver for you card. GeForce Game Ready Driver | 546.01 | Windows 10 64-bit, Windows 11 | NVIDIA
If this all fails, the card may have failed, try it in another computer.

My motherboard is the Asus TUF Gaming Z790-Plus WIFI.

So, I wasn't able to find anywhere where the graphics options were listed. However, here are some things that I picked up on:

• When the display cable is plugged into the card on boot, the VGA light stays on even when I switch the cable to the integrated graphics. However, when I boot the computer with the display cable plugged into the integrated graphics, the VGA light does not turn on at all.
• Only the left (1/2) fan of the GPU is spinning
• In the BIOS, if I go to Advanced\System Agent (SA) Configuration\PCI Express Configuration, I see PCIEX16(G5).......not present. I'm guessing this would usually show my card but I'm not 100% sure.
• In Device Manager, I see a total of 4 "PCI Device"s in the Other Devices column. The location for these 4 devices are in PCI bus 0.

This would indicate that the power cables to the GPU are not plugged in or only one of them is plugged in.

If both are plugged in, then the card may have failed

 

So I just solved the issue. Turns out all I needed to do was update my BIOS to the latest version on Asus' website. I knew something was a bit weird when I checked my BIOS version and saw that it was something like "102" instead of something recent like "1420". Now both fans are spinning and I was able to install drivers!
