Maintenance

Regular maintenance ensures the longevity and optimal performance of your PC.

Dust Filter Cleaning

The ASUS A31 features magnetic dust filters on the top and bottom panels. Regularly remove and clean these filters to prevent dust buildup, which can impede airflow and increase component temperatures.

Tempered Glass Care

Handle the tempered glass panels with care. Use a soft, lint-free cloth and a mild glass cleaner to remove smudges and dust. Avoid abrasive materials that could scratch the glass.

Troubleshooting

If you encounter issues during or after assembly, consider the following common troubleshooting steps:

• No Power: Ensure all power cables (24-pin ATX, 8-pin CPU, GPU power) are securely connected. Check the power supply switch and wall outlet.
• No Display: Verify that your monitor is connected to the graphics card (not the motherboard integrated graphics, unless intended) and that the graphics card is properly seated and powered.
• Overheating: Check fan orientation for proper airflow. Ensure CPU cooler and GPU fans are spinning. Clean dust filters.
• Cable Management Issues: If side panels are difficult to close, re-route cables to utilize the dedicated cable management space more effectively.
• Loose Components: Ensure all components (motherboard, GPU, storage drives) are securely fastened to prevent movement or disconnections.
