How can I diagnose a graphics card error in Windows?


A graphics card error in Windows can be a frustrating experience, particularly when it comes to gaming, video editing, or other 3D graphics-intensive applications. Fortunately for users, there are a few tools available to help them diagnose and fix these types of issues. In this article, we’ll explore how to diagnose a graphics card error in Windows, including tips and tricks for resolving the issue.

What is a Graphics Card Error?

A graphics card error is an issue that occurs when your graphics card driver is not functioning correctly. This can lead to problems such as poor graphics performance while playing games or watching videos, or reduced stability when using 3D graphics applications. Additionally, users may experience graphics glitches, artifacts on their screen, or even their computer crashing.

How to Diagnose a Graphics Card Error

Diagnosing a graphics card error in Windows isn’t as complicated as it may seem. In most cases, users can follow a few simple steps to help identify and troubleshoot the issue.

Step 1: Update Your Drivers

The first step in diagnosing a graphics card error is to make sure that you are running the latest drivers for your graphics card. Outdated drivers could lead to decreased performance or even certain features not functioning properly.

You can download and install the latest drivers for your graphics card from the official website of the manufacturer (Nvidia/AMD). Additionally, users can use specialized software such as Driver Booster to scan their system for outdated drivers and update them automatically.

Step 2: Check for Corrupt System Files

Another potential cause of graphics card errors is corrupt system files. If certain files become corrupt or missing, this can have a serious impact on the performance of your graphics card. To check for system file corruption, open Command Prompt and type in “sfc /scannow”. This will scan your system for any corrupt files and restore them if needed.

Step 3: Run a Test

If you are still experiencing graphics card errors after updating your drivers and checking for corrupt system files, you can run a test on your card to make sure it is functioning correctly. You can use specialized software such as Furmark or 3DMark to benchmark your graphics card and ensure it is operating as expected.


Diagnosing a graphics card error in Windows isn’t as difficult as it may seem. By following these simple steps, users can identify and resolve most issues quickly and easily. By keeping their drivers up to date and running tests to make sure their graphics card is functioning correctly, users can ensure their systems are running at peak performance.
