5. Operating Instructions
5.1. First Boot
After all components are installed and connected, power on your system. The system should initiate the boot process. You may need to install an operating system if it's a new build.
5.2. BIOS/UEFI Setup
To enter the BIOS/UEFI setup, press the designated key (usually DEL or F2) during the initial boot sequence. Here you can configure boot order, system time, and other advanced settings.
5.3. Onboard Buttons and Diagnostic Card
The motherboard includes independent power and reset buttons for convenience during testing or open-bench setups. A diagnostic card (debug LED display) is also present to help identify boot issues by displaying error codes.
6. Maintenance
6.1. General Care
Keep your computer in a clean, dust-free environment. Avoid exposing the motherboard to extreme temperatures or humidity.
6.2. Cleaning
Periodically clean dust from the motherboard and components using compressed air. Ensure the system is powered off and unplugged before cleaning. Do not use liquid cleaners directly on components.
7. Troubleshooting
7.1. No Power/No Boot
- Check all power connections (24-pin ATX, 8-pin CPU, GPU power).
- Ensure your power supply unit (PSU) is sufficient (at least 500W recommended).
- Verify the front panel power switch connection.
- Check if the CMOS battery is installed correctly.
7.2. Diagnostic Card (Debug LED)
The onboard diagnostic card displays codes during boot-up. Consult the motherboard's specific documentation (if available) or common POST code lists online to interpret these codes and identify the failing component (e.g., CPU, RAM, GPU).
7.3. CPU Related Issues
If the system fails to recognize the CPU or shows errors, re-check the CPU installation and ensure no pins are bent or damaged. Refer to the CPU pin warning in Section 3.
