1. Restart your Device

Restart your computer

If you’ve just installed a new graphics card, but your Windows OS isn’t detecting it, it may have failed to install the driver.

Windows 11 usually installs the devices and their drivers when you restart your PC. So, before you try the next methods, make sure to restart your Windows PC and see if it helps.

To restart your Windows 11 PC, click the Start button and select the Power menu. On the Power Menu, select Restart.

2. Disconnect Other Devices Connected to your computer

By the devices, we don’t mean Keyboard and Mouse but other devices like gaming controllers, smartphones, or secondary monitors.

The peripherals connected to your device often conflict with the driver installation, leading to a Graphics card not being detected issue.

So, turn off your computer and disconnect all peripherals connected to your device. Once disconnected, start your PC again.

Maybe your PC is unable to detect the Graphics card because it isn’t installed correctly. If you’re the one installing the GPU unit, you need to take care of these things.

  • Make sure your Graphics Card is connected to the right slot.
  • The power connectors to the GPU are securely connected.
  • Your PC’s monitor is connected to the GPU’s video output.
  • The PCIe slot is free from dust and debris.

If you take care of these few points during the GPU installation, Windows 11 should detect your Graphics card without any issue.

7. Check Your SMPS (Power Supply Unit)

The Power Supply unit should be compatible with the GPU you’ve installed. If it’s incompatible, the power supply unit may fail to deliver the required power that the GPU unit needs.

Sometimes, a faulty PSU is the reason the computer does not detect the GPU. You can rule out these issues by inspecting your Power Supply Unit.

If the connected hardware requires more power, consider upgrading your Power Supply unit. If you suspect a faulty PSU, you can have it checked by a local service center.

8. Check if your GPU unit is faulty

Well, if you have come so far, it’s likely that your PC still isn’t detecting your graphics card.

In this case, you must ensure your graphics card isn’t faulty. Some signs of a graphics card fault are fan noises, PC crashes, graphical errors, frequent BSOD errors, and sudden crashes while gaming.

If you see any of these signs, you likely have a faulty graphics card. You can have your graphics card checked by a local service center.

If your GPU unit is under warranty, you can contact customer service for help with a warranty claim.

9. Revert the Overclocking & Update your BIOS

An outdated BIOS is one leading reason Windows 11 does not detect the graphics card. To update the BIOS, you must head to the motherboard manufacturer’s website and follow the steps.

BIOS update is a complicated method; hence, sticking with the official steps is recommended.

Also, if you recently overclocked or underclocked your GPU unit, you need to undo the changes. Overclocking and underclocking often trigger problems and damage the GPU.
