7. Troubleshooting
If you encounter issues with your PC build, consider the following general troubleshooting steps:
- No Power: Ensure all power cables (PSU to wall, PSU to motherboard, CPU, GPU) are securely connected. Check the power button connection to the motherboard.
- Fans Not Spinning/No RGB: Verify fan power connections to the motherboard or fan controller. Check ARGB connections for lighting issues. Ensure your motherboard's BIOS/UEFI settings or software are configured correctly for fan control and RGB.
- Overheating: Confirm all fans are spinning in the correct direction for optimal airflow. Ensure dust filters are clean and not obstructing airflow. Check CPU cooler and GPU cooler installations.
- USB Ports Not Working: Check the USB header connections from the front I/O panel to the motherboard.
For more specific issues, consult the manuals for your individual components (motherboard, GPU, PSU, etc.) or seek assistance from a qualified technician.
