How to reinstall NVIDIA drivers that don't detect GPU.

I've been having trouble with my GPU (as seen in this post) and was told to uninstall the drivers which would be automatically reinstalled. They were not, and as I tried to reinstall them I was told that it couldn't detect an NVIDIA GPU on my system, the problem I've been having before. My problem is not fixed, has actually gotten worse, and now I no longer have my NVIDIA drivers. Can anyone help me with this?

    Hello TheMenInBlackReal

    Thank you so much for reaching out, I am Udit an independent advisor, and I am glad to assist you today. please follow these steps.

    1. First, please make sure your NVIDIA GPU is properly seated in the PCIe slot inside your computer. If it’s a desktop, you might want to open the case carefully (after shutting down and unplugging the PC) and ensure the card is firmly in place. Also, check that any required power cables are connected to the GPU.
    2. Verify Device Detection in Device Manager

    Right-click the Start button and select Device Manager.

    Look under “Display adapters.” If your NVIDIA GPU is listed there, it means Windows detects it at some level. If it’s missing or showing an “Unknown device,” that indicates the system is not recognizing the GPU correctly.

    1. Uninstall NVIDIA Drivers via Device Manager

    Right-click the Start button and select Device Manager.

    Expand “Display adapters.”

    Right-click on the NVIDIA GPU entry and select “Uninstall device.

    In the dialog box, check “Delete the driver software for this device” if available, then click Uninstall.

    Restart your computer.

    1. Use Windows Update to Reinstall Drivers

    After rebooting, Windows should attempt to detect your hardware and install a compatible driver automatically via Windows Update. To check:

    Go to Settings > Update & Security > Windows Update.

    Click “Check for updates” and allow any optional or driver updates to install.

    1. Use Device Manager to Scan for Hardware Changes

    In Device Manager, click “Action” > “Scan for hardware changes” to force Windows to detect and install drivers for the GPU.

    1. Sometimes Windows hides driver updates under optional updates:

    Go to Settings > Update & Security > Windows Update > Advanced options > Optional updates.

    Look for any NVIDIA driver updates and install them.

    1. After installation, check Device Manager again under “Display adapters” to confirm the NVIDIA GPU is recognized with the driver installed.
    2. If the GPU still isn’t detected, check your BIOS/UEFI settings. Sometimes the onboard graphics are set as primary, which can disable the discrete GPU.

    Restart your PC and enter BIOS by pressing Del, F2, or Esc during boot.

    Look for settings related to graphics or video output and ensure your PCIe GPU is enabled or set as primary.

    1. If the problem persists, try installing the GPU in a different computer to confirm if the hardware itself is working properly.

    If after all these steps your GPU is still not detected, it may indicate a hardware issue. At that point, you could consider reaching out to NVIDIA support or your computer/motherboard manufacturer for further assistance.

    Regards,

    Udit
