Graphics Card not Detected: Solutions to the problem
Below, we’ll go through the best possible solutions to resolve the GPU not recognized issue. We go from simple to more complex solutions that can take a little longer. We will try different software and hardware tricks that we can use to solve the problem for both Nvidia and AMD graphics cards.
Check the physical installation of the graphics card
Yes, it sounds banal, but the dog is often buried here. Before we even test anything else, you should make sure that your graphics card is really fully engaged in the slot. This is often the cause of your Graphics Card not Detected in Windows 10.
To do this, open the cover of your PC case and check whether the graphics card is properly seated in the PCI Express x16 slot or not. To ensure that the graphics card is properly installed in the slot, briefly remove the graphics card and carefully reinsert it. Then you boot up the PC and see if the problem has been resolved.
Eliminate other hardware problems
Are you sure that your graphics card is inserted properly? Then first go through the following list and check everything:
- Check your monitor cable – is it connected correctly and flush?
- Tests the display port, DVI, and HDMI connections of the graphics card – a port may be defective.
- Try a different connection cable to rule out a cable break.
- Make sure that the monitor is really connected to the graphics card.
- Test the PC once on another monitor or your television
- I tried to install the graphics card on another computer and see if it is recognized there
If you’ve checked all of this, but the graphics card is still not recognized, try our other tips.
Avoid conflict with a second graphics card
If you operate two graphics cards or your CPU is equipped with an integrated onboard GPU, this can mean that one of your graphics cards is not correctly recognized. To rule out a possible conflict between two graphics card drivers, we deactivate one of the two cards:
- Press the key combination Windows key + X and open the Device Manager from this list.
- Right-click on the alternative graphics solution and select “Deactivate.”
- Then you confirm the process.
- Then restart the computer and test whether the problem has been resolved and your Graphics Card is not Detected again.
If that tip didn’t work, try the next one below.
Check your BIOS settings
If you are installing your graphics card for the first time, it could also help deactivate the integrated GPU in the BIOS (if available) and set the primary graphics output to PEG (PCI-Express Graphics).
Because if you have both integrated and discrete GPUs, Windows may only recognize them if you activate them directly via the BIOS.
Different BIOS versions have different names for this, but the process of disabling the integrated graphics and setting the primary graphics output to the dedicated graphics card is the same.
Sometimes you will find the setting for this under the menu item “Advanced” or “Chipset” with the names:
- Video configuration
- First display device
- Primary display adapter
The best thing to do is to research your respective mainboard model online, and you should find the whole thing. A little digging around in the BIOS helps too. This step often solves the problem of recognizing your graphics card.
Make sure the graphics card is not disabled
Sometimes this problem can occur if your graphics card is deactivated in the device manager. Proceed as follows to determine whether your GPU is deactivated and thus not correctly recognized:
- Press Windows Key + X to open the Power User menu. Select Device Manager there.
- After opening the Device Manager, find your graphics card and double-click on the entry to display its properties.
- Switch to the “Driver” tab and click on the “Activate device” button below. If the button is missing or you can only deactivate it, as in our case, this means that your graphics card is activated.
In the driver tab of the graphics card, we check whether it is activated.
Installs the latest graphics card drivers
If your Graphics Card not Detected under Windows 10 (regardless of whether it is Nvidia or AMD), it often helps download the latest drivers for your model. Proceed as follows:
- Open the Windows settings and click on Apps.
- Look for your Nvidia or Radeon drivers in the search bar below and uninstall all software connected to Nvidia or AMD / ATI / Radeon / Catalyst. Just click on the software you want to remove and choose Uninstall.
- Follow the instructions on the screen to remove the driver.
This is even clearer with a tool to completely remove old drivers from your PC. We recommend the Display Driver Uninstaller, which you can download here: https://www.guru3d.com/files-get/display-driver-uninstaller-download,20.html.
After you have removed your old drivers, visit Nvidia or AMD websites and download the latest drivers for your graphics card there. When installing the drivers, make sure that you select the Reinstall option. After installation, restart the PC and check if the problem has been resolved.
If that’s not the case, try the next tip.
Even if you already had the latest drivers installed, you should uninstall them and perform a new installation. Since your Graphics Card not Detected, you must, of course, know your model.
Use command prompt
For many people, it happens that the Nvidia driver cannot detect the graphics card. You can fix this problem using the command prompt. Proceed as follows:
- Opens the command prompt as an administrator. To do this, simply search for “Command Prompt” in the Windows search and select the “Start as Admin” option in the menu. Alternatively, you press Windows key + R and enter “cmd” in the window that opens.
- As soon as the command prompt is open, enter the command bcdedit / set PCI-Express force to disable and press Enter to execute it.
- Close the command prompt and try again to install your drivers.
Rule out compatibility problems and check connections
Sometimes compatibility problems can also be the reason why your Graphics Card is not Detected. There are two scenarios for this:
- The probability is small, but if you have an ancient motherboard and recently installed a graphics card, compatibility problems can occur. You can make some BIOS changes to this (more on this in the next section).
- Another problem that can arise is simply a weak power supply. It’s no surprise that the graphics card in many PCs is the most power-consuming device. Therefore, sufficient performance is required. To check whether your PC is getting enough juice, use our power supply calculator.
If you have more than enough power for your card, be sure to check all power cables anyway. Make sure they are all properly connected to the power supply, motherboard, and your GPU.
If your graphics card requires 6-pin or 8-pin PCIe power connections, you have to connect them to your power supply to supply the graphics card with sufficient power.
Update your BIOS
Have you tried everything, but your graphics card is still not recognized? Then you can try to update the BIOS of your motherboard.
As mentioned, it can happen that the graphics card is not compatible with your older mainboard. You could fix this problem with a BIOS update.
To perform the BIOS update, you have to pay attention to a few things:
- First, you have to know which BIOS version you have currently installed. Enter “msinfo32” in the Windows 10 search and press Enter to look at the system information. There you can read out the current BIOS version.
- Then you have to find out which mainboard you have. You can read how it works here.
- Finally, you have to download the current BIOS version from the manufacturer’s website of your motherboard and install it.
We have to mention that updating the BIOS can be dangerous at times. So be extra careful to avoid permanent damage and be sure to install the correct version. You can also find detailed instructions on how to update the BIOS in the manual for your motherboard. The following video explains the whole thing well:
Reset BIOS to factory settings
For those who already had an up-to-date BIOS, or if the previous tip didn’t help, this solution might work. By restoring the BIOS to its original state, your graphics card could be displayed again. Proceed as follows:
- If your PC is switched on, it will restart. If not, switch it on and, depending on the motherboard, press “Del” or “F2” when you are prompted to enter the BIOS.
- Navigates to the BIOS menu
- Look for “Restore To Default” or a variation of it and just hit the Enter key.
- Follow the additional instructions that you will then see.
Resetting the BIOS resets the BIOS to the factory-enabled settings. It won’t erase any data on your hard drive, but it can change settings that you may have changed directly in the BIOS.
Remove new Windows updates
Sometimes it happens that a certain Windows update ensures that your graphics card is no longer recognized. If the problem occurs after a Windows update, you have to find the latest updates and remove them. Proceed as follows:
- Open Windows Settings (look for “Settings” in Windows Search) and click on “Update & Security.”
- Click on “View update history” below.
- Select “Uninstall Updates.”
- A list of the installed updates will then be displayed. Now double-click on an update to remove it.
If removing the updates solves the problem, then you have to block the reinstallation of these updates. Information and instructions can be found on the net.
Restore the old system state
If you’ve tried all of the above but your graphics card is still not Detected, there is one more thing you can try.
Sometimes Windows causes unexpected problems, and there are many scenarios in which the latest Windows updates can cause an error. You can roll back Windows to an earlier period and see if that fixes the problem:
- Type “recovery” in the Windows search bar and click the appropriate button
- Click on “Open System Restore.”
- Click “Next,” select one of the available restore points, and click “Next” again.
- Confirm the action, and your PC will now restart.
- Sign in again and continue with the instructions for the recovery process.
If it still doesn’t work, we still have two possible solutions.
Exclude corrupt GPU BIOS
The video BIOS or the GPU BIOS of your graphics card may be damaged, and therefore your graphics card is not correctly recognized in Windows.
The graphics card may work with normal VGA resolution (as a VGA adapter) using the standard Windows VGA driver. But you cannot install the drivers from the GPU manufacturer (Nvidia or AMD) and increase the resolution. To fix this, you can flash the graphics card BIOS or GPU BIOS with GPU flashing tools.
- NVFlash is the best NVIDIA firmware update tool for updating the BIOS of your Nvidia graphics card. With this tool, you can update the VBIOS and save the current VBIOS for backup purposes. The tool is available here.
- ATI Flash is the best and most secure tool for updating the BIOS of your AMD graphics card. This AMD VBIOS update tool has both a console/command line and a GUI interface. The tool is available here.
Logically, you have to download the current VBIOS for your graphics card model from the manufacturer’s website beforehand. Check out the article on ” Which graphics card do I have ” if you are unsure of the model and BIOS version. With tools like GPU-Z, you can easily read out the BIOS version of your graphics card.
If all else fails: Defective graphics card or PCIe slot
Your Graphics Card not Detected? Then it could be defective. As mentioned above, the best thing to do is to test your graphics card on another PC and see whether it works properly or not. If this is not the case, all you can do is repair, exchange, or buy a new one.
It’s sporadic, but there are times when the motherboard’s PCIe x16 slot is malfunctioning or defective. Even then, you should test the graphics card on another PC. If it works there, there is definitely something wrong with your mainboard, or the mainboard does not support the graphics card.
