There are few things more frustrating than when your display suddenly goes blank in the middle of an intense gaming session or important project.

Fortunately, this problem can be resolved with a little bit of troubleshooting. In this article, we’ll look at the different reasons why your graphics card may be blacking out and what you can do to fix it. So, if you’re tired of dealing with this annoying issue, read on to find out more.

Reasons for Graphics Card Blacking Out

If you have ever experienced a sudden blackout on your graphics card while playing your favorite game or streaming your favorite movie, you know how frustrating it can be. The good news is, most of the time, the issue can be resolved by correctly identifying the reasons and applying appropriate troubleshooting steps. Here are some of the most common reasons why your graphics card may be blacking out:


Overheating is one of the main culprits that can cause your graphics card to blackout. When your graphics card gets too hot, it may shut itself down as a safety measure. There can be several reasons why your graphics card is overheating, such as insufficient cooling, dust buildup, or even overclocking.
To prevent overheating, you can try cleaning the inside of the desktop box, check the cooling unit to ensure proper ventilation, and check if any overclocking configurations are causing the issue. If the cooling hardware is damaged, it may also be necessary to replace it.

Driver Issues

Outdated or corrupted drivers can sometimes cause your graphics card to blackout. The drivers are software programs that enable communication between the operating system and the hardware components. Drivers should always be kept up to date to ensure their compatibility with your graphics card.

To update your graphics card driver, you can visit the manufacturer’s website and download the latest drivers for your specific card. Once downloaded, install the driver and restart the computer to see if the problem has been resolved.

Power Supply Unit (PSU)

The Power Supply Unit is an essential component that provides power to your graphics card. If your power supply unit is underpowered or not compatible with your graphics card, it can cause your graphics card to blackout.

The capacity of your PSU should be compatible with the graphics card, and you should aim to allocate around sixty percent of the PSU capacity to your graphics card. You can also check for symptoms of PSU issues, such as noticeable wiring damage, peculiar noise, or sudden turn off.

It is critical to note that these are just some of the most common reasons why your graphics card may be blacking out. It is crucial to diagnose the issue by thoroughly testing and applying the necessary troubleshooting steps.

Now that we have discussed some of the reasons why your graphics card may black out let’s dive into how to troubleshoot and fix the problem in the next section.

Troubleshooting and Fixing the Problem

If your graphics card is still blacking out despite trying the tips mentioned in the previous section, it’s time to troubleshoot and fix the problem. Here are some suggestions:

Restarting/Power Cycling the System

Sometimes, a simple solution is all that’s needed for the error to get fixed. Power cycling the system will give it a fresh start and can resolve the issue. To do this, turn off the computer, unplug it, and then hold the power button for around 30 seconds. Plug the power cable back in and then turn on the computer.

Checking the Connection

Another reason for graphics card blackouts could be a loose connection. Check to ensure that the graphics card is properly connected to the motherboard and the power supply. Unplug the connections and plug them back in to see if there’s any improvement.

Cleaning the Graphics Card and Fan

Over time, dust and debris can build up in the graphics card and fan, affecting their performance. Turn off the computer, unplug it, and remove the graphics card. Clean it and the fan using a soft-bristled brush, canned air, or a vacuum cleaner. Reattach the graphics card and then power up the system.

Updating and Reinstalling the Drivers

Outdated or corrupted graphics card drivers can result in blackouts. Visit the manufacturer’s website and download the latest drivers for your graphics card. Uninstall the current drivers and then install the new ones.

Replacing the PSU and/or Graphics Card

If none of the solutions above work, you might need to replace the power supply unit (PSU) or the graphics card. A faulty or insufficient PSU can lead to blackouts, as can a malfunctioning graphics card. Both replacements can be a costly and more significant fix, so ensure that it’s the last option after trying all the troubleshooting tips mentioned above.


In conclusion, a graphics card blacking out can be caused by several factors including overheating, driver issues, power supply problems, or even faulty hardware. Troubleshooting these issues can be challenging but there are several practical steps to fix them. Always ensure that your graphics card is up to date with the latest drivers and try to keep your system running cool by ensuring proper ventilation or using additional cooling systems. In some cases, the only solution may be to replace the graphics card or other hardware components, but with careful analysis and commitment, you can successfully revive your graphics card.

Remember, with great power comes great responsibility – and in this case, with great screen resolutions comes great thermal management. Don’t let your graphics card black you out – instead, black out your competition with upgraded hardware and the proper troubleshooting techniques!
