How to fix a graphic card not detected error on your laptop (2022)


0


Graphic cards (also called graphic processing units or GPUs) are necessary hardware units that support our displays when we run complex programs. But when the PC fails to read them, the software will have less support, and you may even encounter a black screen. Luckily, there are several ways to make sure your GPU is compatible with other computer components.

There can be a lot of reasons for this problem. The problem might be because of faulty drivers or incorrect BIOS settings or hardware issues or GPU slot issues. The problem can also be caused by a faulty graphics card as well. Another reason for this problem can be the power supply issue. So, there can be a lot of things that can cause your system to not detect the graphics card and these reasons can vary depending on whether you are using the graphics card for the first time or your system stopped detecting the graphics card out of the blue.

Method 1: Check Graphics Card Slot

Sometimes the issue might be the graphics card slot. There are slots on your motherboard where you can insert your graphics card. One of these slots can be damaged hence causing this issue.

Note: Even if your graphics card was working fine we advise you to check the slots. The slots can get damaged or faulty all of a sudden as well. So, even if your slot was fine there’s still a chance that the problem is caused by your GPU slot.

  1. Open the back cover of your PC
  2. Look at the motherboard and the graphics card slots. Turn on the computer and check if the graphics card is running e.g. its fan is running.
  3. If the graphics card doesn’t turn on then the issue might be with the slot i.e. the slot might be faulty or damaged.
  4. Turn off your computer and take out the graphics card. Insert the graphics card in another slot and check if this makes it work.

If the graphics card is still not getting detected and you have more slots available then try each of them. Sometimes there can be multiple damaged or faulty slots.

Method 2: Uninstall and Reinstall Graphics Drivers

Make sure your graphic card drivers are installed and updated. If you already have the drivers installed then it would be in your best interest to reinstall the drivers (probably clean install) and check if reinstalling resolves the issue.

We have an article that will help you go through the process of uninstalling and reinstalling your graphics drivers without leaving any trace of the previous drivers. Clean installing the drivers help resolve a lot of issues. So, clicking the catalyst control center cannot be started and following the instructions given in either method 2 or method 3.

Once done, check if this resolves your issue or not.

Note: The linked article provides steps for clean installing the AMD drivers. If your graphic card is from another manufacturer then the steps might vary a little bit. However, the general steps are still similar. You should go to the manufacturer’s website and download the latest drivers for your graphic card model. You should also look for a cleanup utility that will erase all the files related to the previous driver. Now, go into Safe Mode > uninstall the drivers > run the uninstall utility > reboot > install the latest drivers, and then get out of Safe Mode.

Method 3: Set your Graphics Card to Default

Sometimes the problem can easily be solved by setting your graphics card as the default graphics. This option is for those who can see their graphic card on their NVidia panel (or other graphic card panels).

Note: The instructions given below are for the NVidia graphics cards. The steps for changing the default graphics card will vary for other manufacturers.

  1. Open the NVIDIA control panel. You can simply right-click on your Desktop and select NVIDIA Control Panel
  2. Click 3D Settings
  3. Select Manage 3D Settings from the left pane. It should be under 3D Settings
  4. Select the Program Settings tab
  5. Now, select a program that you want to select your graphics card for. You can select the program from the drop-down list in the Select a program to customize section
  6. Select High-performance NVidia processor from the drop-down list in Select the preferred graphics processor for this program section

Once done, close the panel and try to run the program that has the NVidia graphics card as the default device. If it runs fine then you can repeat the above steps for other major applications.

Method 4: Check Power Supply

If you are trying the graphics card for the first time and you are sure that your graphics card is fine then the issue could be your power supply. A lot of the time the power supply cannot provide enough power for the graphics card. Even if your graphics card seems to be running it still doesn’t mean that your power supply is properly powering the graphics card.

We cannot tell you how powerful of power supply you need because it depends on your power supply and your graphics card. Some graphic cards need more power than others. So, check the power ratings of your power supply and check how much power your graphics card needs. If your power supply meets the minimum requirements then you need to get a different power supply. Just make sure that your power supply provides a considerable amount more wattage than the power required by your graphics card.

Also, make sure your graphics card is powered properly and the power leads are connected to it. Just because your graphic card’s fans are running it doesn’t mean that the power leads are properly connected. Sometimes the graphic card is partially powered which might be creating this problem.

Note: Make sure you get a power supply from a good manufacturer. These will cost a bit more but it getting a power supply of a good brand will make sure that it delivers the power that it promises. Some of the best brands are EVGA, Corsair, SeaSonic, and Cooler Master.

Method 5: Change BIOS Settings

There are a couple of settings of BIOS that you can change. This will ensure that the problem isn’t caused by incorrect settings of the BIOS.

PRO TIP: If the issue is with your computer or a laptop/notebook you should try using Restor0 Repair which can scan the repositories and replace corrupt and missing files. This works in most cases, where the issue originated due to system corruption. You can download Restoro by Clicking Here

The settings that need to be changed as well as the steps needed to change those settings are given below

  1. Turn on the system
  2. When you restart your computer, press either Esc, F8, F12, or F10 when your manufacturer’s logo appears. You can also check which button to press by looking at the corner of the screen that has your manufacturer’s logo. The button changes from manufacturer to manufacturer.
  3. You might be in the BIOS menu or you might be seeing a list of options. If you are seeing a list of options then there should be a BIOS menu option in that list. You can use the arrow keys to navigate to that option and press Enter to select the BIOS menu.
  4. Look for a setting named IGPU or IGPU Multi Monitors. This setting basically lets you set up and use multiple monitors. If you are using a single monitor then make sure this option is disabled.
  5. Look for settings related to PCI and PCI-E. You should have options like PCI, Onboard, PCI-e, and PCI-e / onboard backup (the options might vary depending on the manufacturer). Try selecting the options related to PCI-e and check if that resolves the issue. If you have multiple options like PCI-e and PCI-e / onboard backup then try to select one at a time and check if it helps resolve the issue.

Method 6: Uninstall Windows Updates

Sometimes the problem is caused by the Windows updates. There are lots of cases where the Windows update introduced a bug that causes problems with the drivers and several other things. So, if you started noticing the problem right after installing the Windows updates or you remember installing Windows updates around the time when you started noticing this issue then there’s a high chance that the problem might be caused by the Windows update.

There is a very easy way to get rid of Windows updates, actually. Windows provide you with an option to roll back to a previous build. Although this option is only available for a short period of time, it’s still worth a check.

Method 7: Restore BIOS to Default

Restoring BIOS to the default has also worked for a lot of users. Simply reset your BIOS to default and check if that resolves the issue.

  1. Turn on the system
  2. When you restart your computer, press either Esc, F8, F12, or F10 when your manufacturer’s logo appears. You can also check which button to press by looking at the corner of the screen that has your manufacturer’s logo. The button changes from manufacturer to manufacturer.
  3. You might be in the BIOS menu or you might be seeing a list of options. If you are seeing a list of options then there should be a BIOS menu option in that list. You can use the arrow keys to navigate to that option and press Enter to select the BIOS menu.
  4. Once you are in the BIOS menu, look for an option named Restore to defaults or a variation of that. Again, the options will vary from manufacturer to manufacturer but you should have this option. Simply select this option and press Enter. Follow any additional on-screen instructions.

Once your BIOS is set back to the default values, reboot and check if it has resolved the issue.

Method 8: Update BIOS

A lot of users resolved the issue by updating their BIOS to the latest version. Updating your BIOS to the latest version makes sure that your system is compatible with the latest hardware. There are, of course, a lot more benefits of updating your BIOS that cannot be covered in this article.

Note: Updating BIOS is a very critical step that requires a little bit of technical knowledge. If you aren’t sure or you haven’t updated the BIOS before then we will advise you to take your computer to an expert or to someone who has some experience in updating BIOS. Any mishap in updating the BIOS can brick your computer.

Make Sure the GPU Is Always Detected

Without a GPU, you won’t be able to access programs that pull a lot of resources from the PC. If the issue is not addressed, the display will fail and you’ll be left with a black screen. However, several methods can offer a solution. You can use the BIOS, Task Manager, or Device Manager to help your PC identify and read the graphics card.
