3. When the driver update is done, restart your computer for the change to take effect.

If no driver update is found by Windows for you, please move on to the next step to update the GPU driver.

2. Update the GPU driver

There are mainly 2 ways you can update your GPU driver: manually or automatically.

Option 1: Update your graphics driver manually

If you’re a tech-savvy gamer, you can spend some time updating your GPU driver manually.

To do so, first visit the website of your GPU manufacturer:

• NVIDIA
• AMD
• Intel

Then search for your GPU model. Note that you should only download the latest driver installer that’s compatible with your operating system. Once downloaded, open the installer and follow the on-screen instructions to update.

Option 2: Update your graphics driver automatically (Recommended)

If you don’t have the time, patience or skills to update the driver manually, you can do it automatically with Driver Easy . Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to be troubled by the wrong driver you would be downloading, and you don’t need to worry about making a mistake when installing. Driver Easy handles it all.

You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 steps (and you get full support and a 30-day money back guarantee):

1. Download and install Driver Easy.
2. Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.
   
3. Click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system. (This requires the Pro version – you’ll be prompted to upgrade when you click Update All.)

Note : You can do it for free if you like, but it’s partly manual.
4. Restart your PC for the changes to take effect.

The Pro version of Driver Easy comes with full technical support . If you need assistance, please contact Driver Easy’s support team at [email protected] .

See if your PC is now detecting your GPU. If the problem remains, please move on.

3. Restore your BIOS settings to default

If you’ve previously overclocked your GPU, or you made certain changes in the BIOS, your PC might not detect your GPU either. To see if this is your case, you can try to restore your BIOS settings to default.

The exact ways of restoring the BIOS settings to default vary for different motherboard manufacturers. Here are instructional posts from some of the most popular motherboard manufactureres. Click to see the instructions for your computer:

• Intel
• Dell
• HP
• ASUS
• MSI
• ASRock
• Acer

If your motherboard is not listed above, you’ll need to go to the support page for your computer and see if you can find the correct instructions on the computer manual.

If restoring your BIOS settings to default still don’t help to make your PC detect your GPU, please move on.

4. Repair damaged or corrupted system files

If the above methods don’t help your PC to detect the GPU, then you may need to repair any damaged or corrupted system files. This is because the integrity of Windows system files are essential for proper operation and stability, while errors in critical system files can cause crashes, freezes, and problems like GPU not detected by PC.

By repairing the core Windows system files, it may resolve conflicts, missing DLL issues, registry errors, and other problems that contribute to the instability of your computer. Tools like Fortect can automate the repair process by scanning system files and replacing corrupted ones.

5. Make sure your GPU is correctly seated

If the above software-related troubleshooting procedures don’t help your PC to detect your GPU, you may need to look at the hardware front. One of the most obvious ways to looks at would be the graphics card itself.

To make sure that the GPU is correctly seated in the correct PCIe slot, you can check its status in Task Manager like this:

1. On your keyboard, press theWindows logo + R keys simultaneously to open the Run box.
2. Typetaskmgr and hitEnter .
   
3. SelectPerformance (the second icon).
   
4. If theGPU option is available, you should see the information about your computer’s GPU on the right side panel.

5. When you can see such information, your GPU should be correctly seated.

But there are still possbilities that your GPU can be detected by your computer but is not correctly seated, so you may also want to check your computer case to make sure that your GPU is not lossen or wrongly inserted into the PCIe slots.

Final thoughts

If none of the above helps to resove the PC not detecting GPU issue for you, you may need to see if the GPU itself is at fault. If you don’t have enough time or energy to run such hardware tests, you can seek help from a hardware technician, and they’ll usually have some professional tools, which are more efficient in diagnosting hardware issues.
