How do I troubleshoot a graphics card issue?


Graphics card issues can range from minor annoyances, such as poor performance or graphical errors, to major ones, such as your computer crashing or being unable to start. The first step in troubleshooting a graphics card issue is to know the specific make and model of your graphics card. Once you have this information, there are several main steps you should take to troubleshoot the issue.

Check for Driver Updates

The most common cause of graphics card issues is missing or outdated drivers. Drivers are small software packages that tell your computer’s operating system how to interact with your graphics hardware. Without the latest drivers, your graphics card may not be able to take advantage of all the features and settings available. Always check your manufacturer’s website for the latest drivers before attempting any other troubleshooting steps.

Check the Power Supply

If your graphics card is not getting enough power, it may be causing your display to flicker or your games to run slowly. Make sure your computer is using a power supply with enough wattage to support your graphics card. If you’re using a laptop, make sure your battery is charged and your power settings are optimized.

Check Your Connections

Another problem that can cause your graphics card to fail is loose or damaged connections. Inspect all the cables and connections to your graphics card. Make sure everything is firmly connected and not damaged or corroded. If your graphics card has an external power connection, make sure it is securely connected as well.

Check for Heat Problems

Graphics cards generate a lot of heat when running, which can cause them to malfunction. If your graphics card is overheating, it may be resulting in poor performance or graphical errors. To test for this issue, download a temperature monitoring program that will display the temperature of your GPU (graphics processing unit). If the temperature is too high, you may need to improve cooling in your case, such as by adding more fans or using a better heatsink.

Check Your System RAM

RAM (random access memory) plays a large role in how smoothly your graphics card runs. Not having enough system RAM can cause your graphics card to slow down significantly. Make sure your system has enough RAM to run your games and applications without any issues.

Check Your BIOS Settings

BIOS settings play a critical role in how your graphics card functions. If your graphics card is not working properly, you may need to make changes to its BIOS settings. To do this, restart your computer and press the key associated with your motherboard’s BIOS setup utility. Once in the BIOS, look for options like “integrated graphics”, “secondary graphics” or “video settings” and make sure they are configured correctly.

Replace the Card

Finally, if none of the above steps helped to solve your graphics card issue, then it is likely that the card itself is the problem. In this case, the only solution is to replace it with a new card. When selecting a new card, make sure it is compatible with your existing hardware, and that it meets your performance needs.


Troubleshooting a graphics card issue can be tricky since there are many different potential causes. Fortunately, by following the steps outlined above, you should be able to find the source of your issue and take the necessary steps to fix it.
