Troubleshooting Your GPU for Visual Glitches
Seeing weird colors or flickering shapes on your monitor? That’s usually a sign of GPU artifacting. Don’t panic; it’s often fixable. We’ll guide you through the steps to get your graphics card working properly again.
Updating Your Graphics Drivers: The First Line of Defense
Outdated or corrupted graphics drivers are a common culprit behind artifacting. Think of drivers like translator software between your GPU and your operating system. If that translation is off, things get messy.
Why Drivers Matter
Graphics card manufacturers, like NVIDIA and AMD, regularly release driver updates. These aren’t just for new games; they often contain bug fixes and performance improvements that can directly address visual glitches. A driver update can be the simplest and most effective fix.
How to Update Your Drivers
Here’s how you can get the latest drivers for your NVIDIA, AMD, or Intel GPU:
- NVIDIA: Visit the official NVIDIA website. Look for the “Drivers” section. You’ll need to know your GPU model and operating system. Download the latest driver and run the installer. A clean install option is often recommended.
- AMD: Go to the AMD support page. Similar to NVIDIA, you’ll select your product series and specific GPU model. Download the Adrenalin Edition software or the driver only. Again, consider a clean installation.
- Intel: For integrated graphics or Intel Arc GPUs, visit the Intel Driver & Support Assistant page. This tool can often automatically detect your hardware and recommend the correct driver.
After installing new drivers, always restart your computer. This ensures the new drivers load correctly.
Checking Your GPU’s Temperature: Is It Overheating?
Your graphics card can get quite hot, especially during intense gaming or demanding tasks. When it overheats, it can start to malfunction, leading to artifacting. Keeping it cool is key to stable performance. If your GPU is running hot, our guide can help you lower GPU temperature.
What’s Too Hot?
Generally, most GPUs are designed to operate safely up to around 80-85 degrees Celsius (176-185 Fahrenheit). However, if you’re seeing artifacting and your GPU is consistently hitting 75°C (167°F) or higher under load, it’s a strong indicator of a thermal issue (AMD, NVIDIA).
Monitoring Your GPU’s Temperature
You can easily monitor your GPU temperature using free software:
- MSI Afterburner: A popular and powerful tool that allows detailed monitoring and tweaking.
- HWiNFO64: Provides comprehensive hardware information, including detailed sensor readings.
- GPU-Z: A lightweight utility specifically for GPU information and monitoring.
Run your favorite game or a stress-testing tool (like FurMark or Unigine Heaven) while keeping an eye on the temperature readings. If they climb too high, you’ve likely found your problem.
Solutions for Overheating
If your GPU is running too hot, here are some common fixes:
- Clean Your PC: Dust buildup is a major enemy of cooling. Open your computer case and use compressed air to clean dust from fans, heatsinks, and case vents. Pay special attention to the GPU’s fans and heatsink.
- Improve Airflow: Ensure your computer case has good ventilation. Make sure intake and exhaust fans are working correctly and aren’t blocked.
- Check Fan Speed: You can often control GPU fan speeds using software like MSI Afterburner. You might need to set a more aggressive fan curve.
- Thermal Paste: Over time, the thermal paste between your GPU’s chip and its heatsink can dry out. If your GPU is several years old, reapplying thermal paste might be necessary. This is a more advanced step.
Ensuring Proper GPU Seating and Power
Sometimes, the simplest physical connections can cause issues. A GPU that isn’t seated correctly or isn’t receiving enough power can lead to artifacting.
Is Your GPU Firmly in Place?
Your graphics card plugs into a PCI-Express (PCIe) slot on your motherboard. Ensure it’s pushed all the way in. You’ll usually hear a click from the retention clip on the slot when it’s properly seated. Also, check that the screws securing it to the back of the case are tight.
Power Connections
Most modern GPUs require extra power directly from the power supply unit (PSU) via 6-pin or 8-pin PCIe power connectors.
- Make sure these cables are firmly plugged into both the GPU and the PSU (if it’s a modular PSU).
- Ensure you are using the correct cables. Do not mix CPU power cables with PCIe power cables.
- Check that your power supply is sufficiently powerful for your components. An underpowered PSU can struggle to deliver stable power, especially under load.

Testing Your Graphics Card in Another System
If you’ve tried the software fixes and checked temperatures, but the artifacting persists, it’s time to consider if the GPU itself might be failing. Testing it in a different computer is the best way to confirm this.
How to Perform the Test
Carefully remove your graphics card from your current PC. Install it into a known-working computer. If the artifacting occurs in the second system as well, it strongly suggests that your GPU is the source of the problem. If the artifacting stops, the issue likely lies with your original computer’s motherboard, PSU, or other components.
Considering Underclocking Your GPU
If your GPU is consistently overheating or showing signs of instability even after cleaning and checking, you might be able to reduce its clock speeds slightly. This process is called underclocking.
What is Underclocking?
Underclocking reduces the operating frequency (speed) of your GPU’s core and memory. This can help stabilize a card that’s on the verge of failure or suffering from heat-related issues. It’s the opposite of overclocking, which aims to increase speeds.
How to Underclock
You can use tools like MSI Afterburner to reduce the core clock and memory clock speeds. Start with small reductions, perhaps 50-100 MHz at a time. After each adjustment, test for artifacting. If the artifacts disappear and the system remains stable, you’ve found a working setting. This is often a temporary fix if the card is failing, but it can help you salvage some usability.
Quick Checklist for Fixing Artifacts
Here’s a quick rundown to help you tackle those visual glitches:
- Update your graphics drivers to the latest version.
- Clean dust from your PC, especially the GPU fans and heatsink.
- Monitor GPU temperatures under load.
- Ensure your GPU is firmly seated in its PCIe slot.
- Verify all power connectors to the GPU are secure.
- If issues persist, test the GPU in another PC.
Conclusion
You’ve now walked through the essential steps to tackle GPU artifacting. Most of the time, issues like outdated drivers or overheating are the culprits. By systematically checking your drivers, temperatures, and physical connections, you can often resolve these visual glitches yourself. If the problem persists after these checks, testing your GPU in another system is your next best move to pinpoint the cause. Don’t give up – taking these actions can save you from unnecessary hardware upgrades and get your display back to normal.
Frequently Asked Questions
How often should I update my graphics drivers?
It’s a good practice to check for driver updates every few months or whenever a new major game is released. Manufacturers often release updates to improve performance and fix bugs that could cause issues like artifacting. You can also subscribe to update notifications from NVIDIA, AMD, or Intel.
Can dust inside my PC really cause GPU artifacting?
Yes, absolutely. Dust acts as an insulator, trapping heat. When your GPU’s heatsink and fans get clogged with dust, the card can’t dissipate heat effectively. This leads to overheating, which is a common cause of artifacting. Regular cleaning is essential for good cooling.
My GPU is showing artifacts, but the temperature looks okay. What else could it be?
If your GPU temperature seems fine, the issue might be with the card’s physical installation or power delivery. Double-check that the GPU is fully seated in its PCIe slot and that all necessary power cables are securely connected to both the GPU and your power supply. A faulty power supply unit could also be a factor.
Is underclocking my GPU permanent?
No, underclocking is not permanent. You can adjust your GPU’s clock speeds using software like MSI Afterburner. The settings you choose will typically apply when you launch the software or when your system boots, depending on your configuration. You can always revert to default speeds if needed.
When should I suspect my GPU is actually failing?
You should suspect your GPU might be failing if artifacting occurs even after you’ve updated drivers, cleaned your PC, ensured proper seating and power, and tested it in another system where the problem persists. If artifacting happens across multiple healthy systems with fresh drivers, the GPU itself is likely the issue.
