8. Troubleshooting
If you encounter issues, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| System does not power on. | Loose power connections, faulty power supply, incorrect front panel wiring. | Check all power cables (PSU to wall, PSU to motherboard/components). Verify front panel power button wiring to motherboard. Test power supply. |
| Fans are not spinning or ARGB lighting is not working. | Loose fan/ARGB connections, faulty fan controller, incorrect motherboard header connection. | Ensure all fan power and ARGB cables are securely connected to the controller or motherboard. Check remote control battery. Verify motherboard ARGB header settings in BIOS/software. |
| Poor airflow or high temperatures. | Blocked dust filters, incorrect fan orientation, insufficient cooling. | Clean dust filters. Ensure fans are oriented correctly for intake/exhaust. Consider adding more fans or upgrading cooling solutions if temperatures remain high. |
