To fix the Nvidia graphics card not detecting issue, you can try updating the graphics card driver.

To manually update the Nvidia graphics card driver, you can go to the manufacturer’s website and download the latest graphics card driver (usually from the SUPPORT page).

Manually updating drivers takes time. If you want to save time on it, you can do it automatically with Driver Booster. Just a few clicks are required.

Here’s how to update your Nvidia graphics card driver with Driver Booster.

2) Launch it and click SCAN to scan your computer to detect any problem drivers.

3) Click the Update button next to the Nvidia graphics card driver to update the driver.

4) Restart your computer and check to see if the problem is resolved.


Method 4: Set BIOS to Default

Incorrect BIOS settings can cause your Nvidia graphics card not to be detected. To fix the issue, you can try setting BIOS to default.

Setting BIOS to default requires a bit of technical knowledge. If you know how to do it, that’s fine. If not, contact the manufacturer or someone who knows how to do it to help with this.


Method 5: Update BIOS

The last method you can try is to update the BIOS. You can download the latest BIOS from the manufacturer and install it on your computer.

Installing BIOS also requires a bit of technical knowledge. If you’re not sure how to do it or you haven’t done it before, contact the manufacturer or someone who has experience on updating BIOS to help with this. Be careful as installing BIOS incorrectly can cause serious system issues.
