Graphics cards are advanced technology that can process and render images on the computer. your system screen. Although they improve your computer’s graphics by speeding up overall graphics processing time, they may not be necessary if you are not doing activities that require heavy graphics processing (like modern games or 3D modeling) on your device.

Part 1. Graphics Card Error Overview

Graphics card errors can cause your device to malfunction periodically, especially during heavy gaming. Your computer may freeze, freeze, freeze, and the screen’s color display may be abnormal or strange color patterns may appear on your screen.

Here are some symptoms to be aware of:

  • Road accidents
  • Computer screen goes blank while other keyboard or CPU lights are on (indicating a working computer)
  • Fan noises (which may be coming from your system’s motherboard or graphics card cooling system)

These are all symptoms of a bad graphics card. This guide offers several ways to fix these errors, but before we get to the fixes available for bad graphics cards, here are a few things you should know:

1. What is a graphics card?

A graphics card is a piece of graphics enhancement technology; it can be a display adapter or a video card built into the motherboard of a computer or installed and connected to the motherboard externally. The graphics card is a part dedicated to providing very clear or high definition graphics data. In most cases, large games or 3D modeling software require a high GPU (Graphics Processing Unit) which may not be natively built into your device. In this case, a graphics card will be required for an optimal user experience.

2. What can cause a graphics card to fail?

There are many errors that can cause your graphics or video card to fail. Here is a summary of what leads to a faulty graphics card:

  • Poor ventilation
  • Device overheating
  • Dead graphics card fans
  • Blown Capacitors
  • Overwhelmed Drivers
  • Insufficient GPU power supply

There are many causes of graphics card failure, but the ones listed above are generally the most common. In general, the main causes are overheating and power supply problems. The effects of overheating can be serious and immediate (usually the cause of video card error 43). Your graphics card is an electronic device made up of tiny electronic components such as resistors and capacitors; an increase in temperature beyond the limit of your board can cause physical damage to these components.

In addition, your GPU (Graphics Processing Unit) requires constant and sufficient power supply, especially when playing games that heavily use your GPU.

1. Cool temperature

cool down graphics card

Overheating is one of the most common causes of graphics card errors. Whether the graphics card comes with its own cooling system or depends on the cooling system of the main device, it needs adequate ventilation.

One way to tell if your motherboard or graphics card is overheating is to hear a sudden fan noise in your device after launching a video game that is using your GPU a lot. Always use your device in well-ventilated places, especially when playing games. All heat generated by your computer’s motherboard must be dissipated.

2. Update Drivers

Besides the possibility that your graphics or video card drivers are outdated, it’s a good idea to always check and update your drivers. Updating your graphics card drivers is a good way to keep up with ever-changing gaming technologies.

Check the link that corresponds to the manufacturers of your graphics card;

  1. NVidia
  2. AMD
  3. Intel

Better yet, you can automatically update drivers on Windows by following these steps:

Step 1. Launch Device Manager

Hold down the Windows key + R on your keyboard, type cmd in the dialog box that appears and launch the Windows command prompt.

Step 2. Type ‘devmgmt.msc’ in the window and press Enter on your keyboard.

You can also simply click on the Windows icon at the bottom left of your screen and type “Device Manager” in the search box to find and launch it.

Step 3. Expand “Display Adapters”.

Step 4. Select the name of your graphics card and click the “Update” icon.

select graphics card

update graphics card

Step 5. Select search method

search for updates

successful update

3. Is your graphics card enabled?

It’s unlikely that your graphics card is disabled, but why wonder if you can easily check to confirm?

You can enable or disable your graphics card from Windows Device Manager. You can open Device Manager in Windows by typing “devmgmt.msc” in Windows Command Prompt. Launch device manager and double-click on the “Display Adapters” option and right-click on your graphics driver to enable or disable it. You must restart your device for your action to take effect correctly.

4. Check the status of your graphics card

Go to your device manager again under the “Display Adapters” option and right-click on your graphics card and display properties. From the properties page, you will be able to see the status of the device. Error codes like code 43 or 12 may be displayed. Any error code definitely points to an error on your graphics card. The next step (if you find an error code) will be to follow the troubleshooting methods and guide to fix the graphics or video card error.

5. Physically clean your device or check your drivers

If your graphics card issues persist, you should probably remove your graphics card and wipe it clean. If you are not a computer technician, you should leave this process to a computer technician. As most graphics drivers have their own cooling system (fans), it is also necessary to check and confirm if the fans are working. Non-functional cooling fans will definitely cause the graphics card to overheat and will likely affect your system’s motherboard as well.

6. Get a replacement for your video card

It’s very easy for a bad computer screen to show colors or turn off periodically – which can easily be mistaken for a graphics card error! One way to confirm that the fault is with your graphics card and not your device itself is to replace your graphics card with another one. You can use a friend’s or buy one. If the latest graphics card is not working, the fault is most likely in your primary device. However, if the new graphics card works, you probably worked with a damaged graphics card. In this case, you will have to replace it.

7. Contact your graphics card manufacturers

The manufacturers of your graphics cards will certainly know what is wrong with your card if you contact them and explain the symptoms to them. Most manufacturers offer a replacement if the cooling system fails, or at least give you a more detailed explanation and tell you what to do.

8. Is it correctly placed in the PCI slots?

Graphics cards must be properly connected to all terminals or PCI slots before functioning as intended. You need to check whether it is well installed or not.

Step 5: Save the video

Click the “Save” button on the upper right part of the interface and another dialog box will appear. There you will see the following prompt: “Select a location to save the recovered files. Please do not save the files to the path where you lost them”. This may help prevent some persistent issues.

You can choose any place or drive, as long as you have enough space. Choose “D” or “E” drive, but it is not advisable to choose “C”. You have two options: If you click on the “Recover” button, the repaired video will be saved in the drive you have chosen, but if you click on the “New Folder” button before the “Recover” button, the repaired video will be saved in the “New Folder”. It’s very simple, isn’t it?

It is advisable to give a name to the new folder, so searching or locating will be even easier. This is especially important if you have a large number of files on your hard drive. Just wait a few seconds and the repaired video will be saved.
