8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| System does not power on. | PSU switch off, power cables loose, front panel connectors incorrect. | Ensure PSU switch is ON. Check all power connections (24-pin, CPU, GPU). Verify front panel power switch cable is correctly connected to motherboard. |
| Fans are not spinning or RGB not working. | Fan cables loose, ARGB hub not powered, motherboard sync issue. | Check fan power cables. Ensure ARGB hub is connected to PSU. Try cycling modes with the LED button. If using motherboard sync, check software settings. |
| USB ports on top panel not working. | USB 3.0 header cable not connected to motherboard. | Verify the USB 3.0 cable from the top I/O panel is securely connected to the USB 3.0 header on your motherboard. |
| Poor airflow or high temperatures. | Dust buildup, incorrect fan orientation, insufficient fans. | Clean dust filters and internal components. Ensure fans are oriented for optimal intake/exhaust. Consider adding more fans if temperatures remain high. |
