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.
NOTE
1. Enable the hidden devices and graphics card driver
- Right-click the Start icon, then select the Device Manager option.
- Select the View button at the top, then click Show hidden devices.
- Expand the Display adapters section, right-click on the GPU, and then choose Enable device if it’s currently disabled.
2. Install or update the graphics card driver
2.1 Via Device Manager
- If the PC is not detecting your GPU, right-click the Start icon from your Taskbar, then select Device Manager.
- Expand Display adapters, right-click your graphics card driver, and click Update driver.
- Click Search automatically for drivers, then reboot your computer after the process is finished. The PC not detecting AMD graphics card issue will be solved.
2.2 Via the manufacturer’s website
- Navigate to Nvidia’s official website or AMD, depending on your GPU, then choose your Product type, series, your OS, download type, and language that fit your GPU description, then click the Search button.
- Click Download under the resulted driver, then double-click the exe file to install it on your PC. Restart your PC afterward to apply the changes made. The PC not detecting GPU error will be fixed.
2.3 Via Windows Update
- Press Windows + I together, then go to Update & Security.
- Click the View all optional updates option on the right.
- Expand the Driver updates section, tick all the updates in there then select Download and install.

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.
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.
- Download and install the Outbyte Driver Updater app.
