5. Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your PC case and components.

- Screw Tightness: Occasionally check that all screws, especially those securing components, are appropriately tightened.
6. Troubleshooting
If you encounter issues, refer to the following common troubleshooting tips:
- No Power: Ensure the power cable is securely connected to both the power supply and the wall outlet. Check the power switch on the power supply unit. Verify all internal power connections (24-pin ATX, 8-pin CPU, GPU power).
- No Display: Confirm that your monitor is connected to the graphics card (not the motherboard's integrated graphics ports, unless you are using integrated graphics). Reseat the graphics card and its power cables.
- Overheating: Check that all case fans and CPU cooler fans are spinning correctly. Ensure no cables are obstructing airflow. Verify CPU cooler installation.
- USB/Type-C Ports Not Working: Ensure the front panel USB/Type-C cables are correctly connected to the motherboard headers.
