How To Know if GPU is Failing – Comprehensive Guide

A GPU, or graphics processing unit, is a computer chip that performs rapid mathematical calculations, primarily for the purpose of rendering images.

Since GPUs are designed to handle large amounts of data at high speeds, they are often used for video and image processing tasks. They can also be used for more general-purpose computing, such as machine learning.

However, like any other computer component, GPUs can fail. In this article, we’ll discuss how to know if GPU is failing, and what you can do about it.

What Causes GPU To Fail?

Most people might not find that their graphics card is dying/failing until their gaming PC crashes in the middle of the game and smoke start coming out of the PC’s case.

In most cases, people know that their graphics card is failed when they can’t reboot their computer system.

However, there are a few other reasons as well that make GPU stop working. These reasons are as follows:

  1. Using GPU to play games that aren’t compatible with your system drivers.
  2. Incompatible installation of a graphics card.
  3. Graphics card’s component failure due to the manufacturer’s faulty manufacturing.
  4. Overclocking with high voltage.
  5. Using faulty PSU’s
  6. Overheating is caused by static overload or too much dirt.

To avoid these issues, you need to inspect your computer system regularly both physically & digitally.

Major Signs of GPU Failing

It’s not easy to admit, but when your computer’s graphics processing unit (GPU) starts to show its age, it’s time to start thinking about replacing it. Just like any other piece of hardware in your system, a GPU can only last for so long before it starts to show its age.

There are a few telltale signs that your GPU is on its last legs. If you start to notice any of the following, it might be time to start shopping for a new GPU.

1: Your System Starts Crashing

One moment, your GPU will be running a highly-intensive game without causing any issues. Then, your system immediately shut down.

And when you try to reboot, you hear a beeping sound, while your motherboard shows error codes.

We know that some motherboards are built with special sensors to indicate faulty computer components when they fail. As a result, the motherboard will notify the user by displaying an error code that indicates which component is failed.

2: Your Games Are Starting to Stutter

This is the most common sign that your graphics card is starting to die when your games begin to shutter. This happens because your system’s GPU is unable to render graphics to your monitor.

Note: This can also happen when your graphics card isn’t compatible with the software your game runs on.

Moreover, a failing GPU will also show several other signs including screen glitches, flickering, and of-color pixelation.

3: Unusual Fan Noise

Modern GPUs come with cooling fans that are used to provide cooling when the graphics card is under heavy load. Although, GPU fans do not run at high RPM until when the GPU is undergoing stress. This prevents fans from damaging.

When you start performing GPU-intensive tasks like programming, or video editing, your graphic’s fan’s bearing is worn and they will stop working. So, your GPU is likely to die out as well.

4: Reduced Performance

Instability and reduced performance is also a sign of GPU failing. You will notice a drop in frame rates and your games will start crashing while displaying a message that the “Display driver has stopped”.

5: You Can’t Run Latest Games

If you find that you can’t run the latest games at a playable framerate, it’s a good indication that your GPU is too old to keep up. This is especially true if you’ve been able to run the game on previous versions of your GPU without any issues.

6: You Will See Blue Screens or Other Errors

If you start to see blue screens or other errors when trying to run certain games or applications, it could be a sign that your GPU is failing. This is often caused by a failing GPU chip or a lack of onboard RAM.

If you notice any of the above signs, it’s a good indication that your GPU is on its last legs and needs to be replaced.

What To Do if Your GPU Fail?

If your GPU fails, you should start checking loose connections, because loose connections can cause a lot of issues, especially with graphics cards.

Therefore, make sure the connections are properly seated in the motherboard and also make that the secondary connection is also secure.

The next thing you can do is to run a software test and monitor real-time temperature for any oddities.

You can also try reinstalling your GPU drivers. If that doesn’t work, then you should contact your GPU manufacturer for support.

Frequently Asked Questions

How do I know my GPU is failing?

There are a few signs that your GPU may be failing. If you notice any unusual graphical glitches or artifacts, your GPU is likely failing.

Additionally, if you experience any crashes or freezes while gaming or using graphics-intensive applications, your GPU may be failing.

How do I test my GPU?

There are a few different ways to test your GPU. One way is to use a benchmarking tool such as 3DMark or Unigine Heaven.

Additionally, you can test your GPU by running graphics-intensive applications or games and monitoring your framerate and performance.

What are the consequences of a failing GPU?

If your GPU is failing, you may experience reduced performance, graphical glitches, and crashes. Additionally, your PC may be unable to run certain applications or games.

Can a failing GPU be repaired?

In some cases, a failing GPU can be repaired. However, it is often more cost-effective to simply replace the GPU.

What are some common causes of GPU failure?

Common causes of GPU failure include overheating, hardware defects, and driver issues.


A failing GPU can cause a number of problems, from artifacts to stuttering and freezing. If you think your GPU is failing, try the above-mentioned methods, if that doesn’t work, then take your computer to a qualified technician to have it replaced.

When shopping for a new GPU, keep in mind the type of games you’ll be playing, the resolution you’ll be playing at, and the amount of VRAM on the card.
