How To Check If A GPU Is Working Properly

Your GPU, or Graphics Processing Unit, is responsible for rendering images, video, and animations on your computer. Whether you’re an avid gamer, video editor, or someone who uses graphic-intensive software, ensuring that your GPU is in proper working condition is essential for optimal performance.

1. Check for Physical Signs of Damage

Before diving into software-based testing, it’s a good idea to inspect your GPU physically. Here are a few things to look for:

• Ensure Proper Seating: Open your case and make sure the GPU is securely seated in the PCIe slot. Sometimes, a loose connection can cause malfunctions.
• Check for Dust and Debris: Dust can accumulate over time, leading to overheating. Clean out any visible dust using compressed air, focusing on the fans and heatsink.
• Inspect Power Cables: Ensure all power cables are properly connected to the GPU. A lack of power can cause your graphics card to malfunction.

2. Monitor Temperatures

Overheating is a common issue for GPUs, especially during gaming or rendering tasks. To ensure your GPU is not overheating:

• Use Monitoring Tools: Software like MSI Afterburner or HWMonitor allows you to keep an eye on your GPU’s temperature in real time.
• Ideal Temperatures: Idle temperatures should typically be between 30°C and 50°C, while under load (gaming or rendering), they shouldn’t exceed 85°C. Consistently high temperatures may indicate an issue with the cooling system.

3. Run a Benchmark Test

A benchmark test will push your GPU to its limits, giving you a clear indication of its performance.

• Popular Tools: Applications like 3DMark, Unigine Heaven, or FurMark allow you to run performance tests on your GPU.
• How to Interpret Results: Look at your GPU’s score and compare it with similar models online. Significant differences in performance could indicate an issue, such as throttling or hardware degradation.

4. Test for Artifacts and Visual Errors

Artifacts are unusual visual glitches that appear on your screen when your GPU isn’t rendering graphics properly. These can include screen tearing, color distortion, or flickering.

• Stress Test Tools: Use a stress testing tool like FurMark to push your GPU. If you notice any artifacts during the test, this could indicate a problem.
• Try Different Games or Software: Run a variety of games or applications to see if the artifacts persist across different programs. If they do, this is a strong sign your GPU may be malfunctioning.

5. Check the GPU’s Driver

Outdated or corrupted drivers can cause performance issues and malfunctions with your GPU.

• Update the Drivers: Visit the manufacturer’s website (e.g., NVIDIA or AMD) and download the latest drivers for your GPU model.
• Use Driver Cleanup Tools: In case your current drivers are corrupted, use a tool like Display Driver Uninstaller (DDU) to remove them completely before installing the new ones.

6. Use Diagnostic Tools

Windows and third-party software offer built-in diagnostic tools that help test GPU health:

• DirectX Diagnostic Tool (DxDiag): On Windows, you can run DxDiag to check if Windows detects any problems with your GPU.
  • Open the Run dialog (Win+R) and type dxdiag.
  • Go to the “Display” tab and check for errors or issues related to the graphics card.
• Third-Party Diagnostics: Tools like GPU-Z can provide detailed real-time information on the health and performance of your GPU, such as clock speeds, memory usage, and voltage.

7. Check for System Crashes or Blue Screens (BSOD)

Frequent crashes, freezes, or BSODs (Blue Screen of Death) while gaming or working on graphic-intensive tasks can be indicators of a failing GPU.

• Investigate Crash Logs: Use the Event Viewer on Windows to view system crash logs. If you see errors related to your GPU, this could suggest hardware failure or instability.
• Stress Testing: Run extended stress tests using tools like FurMark or Unigine Heaven. If your system crashes consistently under load, the GPU may not be functioning correctly.

8. Test on Another System

If possible, install your GPU in another system to rule out motherboard, PSU, or other component issues. If the GPU works perfectly on a different system, the problem may lie elsewhere in your original setup.

9. Consider Professional Diagnostics

If the above tests don’t help pinpoint the issue and your GPU is still under warranty, it may be best to send it to the manufacturer or a professional for diagnostics and potential repairs.
