Outdated or corrupted GPU drivers are a frequent cause of graphical artifacts. To address this, updating drivers to the latest version is often the first step. Visit the official website of your GPU manufacturer (NVIDIA, AMD, or Intel) to download the most recent drivers compatible with your system.

If updating does not resolve the issue, a clean reinstall of the drivers can eliminate corrupted files or conflicting settings. Follow these guidelines for a clean reinstall:

  • Uninstall existing GPU drivers completely using tools like Display Driver Uninstaller (DDU) in Safe Mode.
  • Restart the computer to ensure all remnants of previous drivers are removed.
  • Install the latest driver package downloaded directly from the GPU manufacturer’s website.
  • Restart the system again to finalize installation.

This process helps ensure that the GPU software environment is stable and free from conflicts that could cause artifacts.

Checking and Improving GPU Cooling

Overheating is a prevalent cause of GPU artifacts and can lead to permanent damage if not addressed promptly. Ensuring efficient cooling is critical for maintaining GPU stability and longevity.

Steps to improve GPU cooling include:

  • Cleaning dust from GPU fans, heatsinks, and case ventilation to enhance airflow.
  • Reapplying thermal paste on the GPU chip if the existing paste has dried out or degraded.
  • Ensuring the PC case has adequate ventilation and that intake and exhaust fans are functioning correctly.
  • Considering aftermarket GPU coolers or liquid cooling solutions for high-performance or overclocked GPUs.

Using temperature monitoring software, keep GPU temperatures ideally below 85°C under load. Temperatures consistently above this range can cause thermal throttling and artifacts.

Adjusting GPU Clock Speeds and Voltage

Overclocking the GPU beyond its factory settings can improve performance but may also cause instability and artifacts if done improperly. Reducing clock speeds and adjusting voltages can stabilize the GPU and eliminate artifacts caused by overclocking.

Key recommendations include:

  • Gradually lowering core and memory clock speeds using overclocking software.
  • Monitoring artifact occurrence during stress tests after each adjustment.
  • Avoiding voltage increases unless necessary, as excessive voltage can generate heat and damage components.
  • Restoring factory default settings if artifacts persist after adjustments.

Maintaining a balance between performance and stability is crucial when tuning clock speeds and voltages.

Testing with Different Hardware and Configurations

Isolating the problem may require testing the GPU in different hardware configurations. This helps determine if the issue is with the GPU itself or other system components.

Consider the following tests:

  • Installing the GPU in another compatible system to see if artifacts persist.
  • Using a different PCIe slot on the motherboard to rule out slot damage or connectivity issues.
  • Testing with another known-good power supply to ensure stable power delivery.
  • Running the system with minimal peripherals and background processes to avoid software conflicts.

These steps help verify whether artifacts are caused by the GPU or external factors.

Recognizing When Hardware Repair or Replacement Is Necessary

If artifacts continue despite thorough software troubleshooting and cooling improvements, the GPU may have sustained hardware damage. Common hardware issues include:

  • VRAM defects or corruption.
  • Damaged GPU die or PCB.
