As troublesome as it may seem, this is not an uncommon situation. So, if you’re stuck with a PC not detecting GPU, fix the problem with the solutions below.

Why is my PC not detecting the GPU?

The motherboard not detecting GPU issues can be caused by several reasons that vary from user to user. However, the most common ones are the following:

Outdated drivers – Everyone should make time in their weekly routines to complete the duty of keeping their drivers up to date. They’ll not only make your computer run more slowly, but they will also interfere with its operation, including the GPU not detected but fan spinning issue. Disabled GPU driver – We have shown below how to enable the driver, as well as show hidden devices inside Device Manager to fix the GPU turns on but is not detected error. Faulty card – Check to see if your graphics processing unit (GPU) is properly connected to your motherboard and examine it for any signs of damage. Outdated BIOS – An out-of-date BIOS could create compatibility problems for hardware. This may be the primary reason why the GPU is not detected in Device Manager; thus, it is recommended that you update it both in Windows 10 and Windows 11. Unsuccessful Windows updates – Windows updates generally improve your computer. However, they sometimes bring with them new problems that cause your computer to behave unnaturally. In this scenario, you will need to remove the most recent update.

What can I do if my PC is not detecting GPU?

Before applying the troubleshooting methods below, check the following aspects:

Check your GPU slot and clean it carefully, so you don’t damage any hardware parts. Unplug and replug the GPU back into your motherboard. Many reported that using a different PCI-E port fixed the issue, so try that. Check your connections, and make sure that GPU is properly seated and that the power cable is connected firmly to it. Ensure your power supply can produce enough power to handle your GPU. In the BIOS, set the CPU startup voltage to Maximum and verify if that resolves the problem.

These are some general checks you can perform if you’re not getting any pictures on your display.

1. Enable the hidden devices and graphics card driver

2. Install or update the graphics card driver

2.1 Via Device Manager

2.2 Via the manufacturer’s website

2.3 Via Windows Update

2.4 Automatically install the latest drivers

This is an obvious but common mistake. After installing the graphics card, Windows will automatically install the required graphics card driver that came pre-built into the graphics card. SPONSORED However, most of the time, you need to update the drivers and download additional files to make it run properly. You can download the latest version of the graphics driver from the GPU manufacturer’s website. Alternatively, you can use an automated tool that will handle this task for you. DriverFix is just what you need.

3. Use Command Prompt to disable PCI Express

4. Reset your BIOS and update it

We must point out that changing the BIOS can occasionally be a potentially risky activity; as a result, you should exercise extra caution to prevent causing any irreparable harm. Disclaimer: this program needs to be upgraded from the free version in order to perform some specific actions.

5. Uninstall the latest Windows update
