The graphics card, or GPU, is an essential component for gamers and professionals working with graphics and video. However, like any other hardware component, GPUs can have problems that can affect performance and the overall user experience. In this article, we will explore the most common GPU problems and provide you with effective solutions to solve them.
Black screen
One of the most common problems that can occur with the GPU is a black screen. If you turn on your PC and nothing appears on the screen, it could be a sign of a problem with your graphics card. However, before you conclude that the GPU is faulty, it is important to look closely at other possible causes of the problem. Here are some solutions you can try:
Restart the graphics driver: Press Windows Key + Ctrl + Shift + B to restart the graphics driver. This may fix the problem and get your graphics card working again.
Reboot yourPC and turn off and on your monitor: Sometimes, turning off and on your monitor can solve the problem. Although it seems like a trivial operation, sometimes it is enough to restore proper GPU operation.
Try a different video output: If your computer has multiple video ports, try connecting your monitor to a different port. For example, if you are using HDMI, try using DisplayPort or vice versa.
Try connecting to a different display: If you have a spare monitor available, try connecting your graphics card to that monitor to see if the problem is due to the original display or a compatibility issue.
Relocate the graphics card: If you are familiar with opening your PC, you can try removing the graphics card and reinserting it. Also be sure to check the PCI-Express power connectors and reinsert them properly.
Try a different graphics card slot: If your motherboard has multiple graphics card slots, try inserting the card into a different slot. This may result in reduced performance on some motherboards, but if it works, it is better than a black screen and may help you in the troubleshooting process.
Try a different graphics card: If none of the previous solutions work, you may need to use a different graphics card (or integrated graphics, if possible) to confirm that it is indeed the GPU that is the problem.
Uninstall the GPU drivers: If you can get the system working with a different graphics card or with integrated graphics, try uninstalling your graphics card drivers. Then reinstall the GPU and try running the system with the default Windows drivers. If it works, you can reinstall the drivers later.
If all the above solutions do not solve the black screen problem, it may be time to consider buying a new graphics card.
Visual artifacts
Another common problem that can occur with graphics cards is the appearance of visual artifacts. These can manifest as colored squares, lines or game elements flashing or being displayed incorrectly, or even the screen flashing. Here are some steps you can follow to diagnose and fix the problem:
Disable overclocking: If you have overclocked your graphics card, try disabling it. You may have pushed the card too hard. Alternatively, reduce the overclock until the artifacts disappear, or increase the voltage if you have sufficient thermal and power space.
Reinstall GPU drivers: Often, GPU problems can be solved by reinstalling drivers. Be sure to download and install the latest version of the drivers from your graphics card manufacturer’s site.
Try a different power supply: If you have a backup power supply, try using a different one to see if the problem goes away. An old or underpowered power supply could cause artifacts when the graphics card is stressed.
Check to seeif it is an overheating problem: Overheating is a major cause of GPU artifacts. Check the temperatures of your graphics card and, if necessary, improve the cooling system. See the next section for additional suggestions.
Check the card for signs of wear and tear: Visual artifacts can be a sign that your graphics card is about to fail. Before you toss it, check for any physical problems. Is there a cable preventing the fans from rotating? Are the power cables plugged in correctly? Is the card properly inserted into the PCI-Express slot? Have the RAM heat sinks fallen out? Fix any problems you are experiencing.
Look for solutions specific to your graphics card: Some cards may have common problems and you may need to make specific changes, such as increasing the voltage or power limit or improving the cooling system. Check to see if other users have experienced similar problems with your graphics card and if they have found specific solutions.
If none of the above solutions work, you may have a GPU that is about to fail. If possible, use an alternative card or upgrade.
Poor performance
If you notice that your GPU is not producing the frame rates you want or is not supporting the resolutions and detail settings you expect, here are some suggestions for improving performance:
Reinstall GPU drivers: You may have a corrupt or outdated driver that is preventing your graphics card from operating at its full potential. Uninstall existing drivers and install the latest version from the manufacturer’s website.
Check temperatures: Monitor the temperatures of your graphics card, especially during gaming. If it overheats, consult the next section to improve performance through better cooling.
Check if your GPU is powerful enough: Does your graphics card have enough power to handle the games you want to play? Check the system requirements of your favorite games to see if your GPU is powerful enough. If not, you might consider an upgrade.
Overclock your GPU: If you want to improve the performance of your graphics card, you can try overclocking it to make it slightly faster. However, be careful not to push the card too hard and carefully monitor temperatures when overclocking.
Overheating
If you have been checking your GPU temperatures while gaming or rendering video and have noticed that the card is overheating or triggering thermal protection, it is important to take action to fix the problem. A GPU that runs too hot will not offer optimal performance and may have shortened life. Here are some suggestions for dealing with overheating:
Clean your PC case: If your graphics card is overheating, it may not have adequate access to fresh air. Check your case’s dust filters to see if they need cleaning and remove dust from any internal radiators or heat sinks, including the graphics card’s. For more tips on how to clean your computer safely and effectively, see our guide on how to clean your computer.
Change the GPU fan curve: You may only need to set a custom fan curve to make the graphics card fans run faster and keep the GPU cool. Use MSI Afterburner to create a custom fan curve to improve cooling performance.
Improve your cooling system: Increasing your GPU’s access to cool air might mean adding more fans or larger fans to your case to increase the amount of cool air reaching your card every second. You might also consider adding exhaust fans (or other fans) to better remove hot air from the case.
Cable management: If you have a lot of cables in your case, they may impede airflow and prevent proper cooling. Try arranging cables on the sides of the case or behind the motherboard panel to improve airflow through the case.
Move add-on cards: If you have add-on cards such as a USB card or network card that are placed very close to your GPU, try moving them to another PCI-Express slot to create more space for cooling.
Undervolting and underclocking the GPU: If you still encounter problems with overheating, you can try reducing the GPU voltage or even reducing its frequency to reduce power consumption and, consequently, heat production. See our guide on undervolting for more information.
