• Surface Cleaning: Wipe the exterior surfaces with a soft, dry, lint-free cloth. Avoid using liquid cleaners directly on the card.

5.2 Storage

If storing the graphics card for an extended period, place it in an anti-static bag and store it in a cool, dry environment away from direct sunlight and extreme temperatures.

6. Troubleshooting

This section addresses common issues you might encounter with your graphics card.

6.1 No Display Output

• Ensure the display cable is securely connected to both the graphics card and the monitor.
• Verify that the graphics card is properly seated in the PCIe slot.
• Check that all power connectors are firmly attached to the graphics card.
• Confirm your monitor is set to the correct input source.
• Try a different display cable or monitor to rule out external issues.

6.2 Performance Issues or Crashes

• Ensure you have the latest graphics drivers installed from the NVIDIA website.
• Check your system's power supply. An 850W PSU is recommended for this card. Insufficient power can lead to instability.
• Monitor GPU temperatures using MSI Afterburner or similar software. Overheating can cause performance throttling or crashes. Ensure adequate case airflow.
• Verify that your system's CPU and RAM meet the recommended specifications.

6.3 Fan Noise

• Check for any obstructions in the fan blades.
• Use MSI Afterburner to adjust the fan curve.
• Ensure your case has good airflow to prevent the card from running too hot, which would cause fans to spin faster.
