2. Operating
2.1 BIOS Setting
The BIOS (Basic Input and Output System) stores hardware parameters in the CMOS on the motherboard. It performs the Power-On Self-Test (POST) and loads the operating system. The BIOS Setup program allows you to modify basic system configurations.
Important Note on BIOS Flashing:
- BIOS flashing is potentially risky. Only flash the BIOS if you encounter problems that require it.
- Inadequate BIOS flashing can lead to system malfunction. Unauthorized BIOS flashing may void your warranty.
2.2 Enter BIOS Setup
To enter the BIOS Setup Menu:
- Turn on your computer.
- During the self-test process, press the 'DEL' key when prompted.
- Alternatively, you can use the 'F11' key as a Quick Boot Key.
If the prompt disappears too quickly, you can restart your computer by pressing the Reset button on the case or by pressing Ctrl+Alt+Delete simultaneously.
2.3 Reset BIOS
To restore default BIOS settings or resolve certain issues, you can reset the BIOS by clearing the CMOS:
Important Safety Note:
- Ensure the computer is completely off before clearing CMOS data.
Locate the JCMOS1 jumper on the motherboard. To clear CMOS:
- The initial state covers pins 1 and 2.
- Pull out the jumper cap and place it to cover pins 2 and 3. Wait for approximately 3 minutes for the discharge to complete.
- Restore the jumper cap to its initial state (covering pins 1 and 2).
3. Maintenance
Regular maintenance helps ensure the longevity and stable operation of your motherboard.
- Keep Clean: Periodically clean dust from the motherboard and components using compressed air. Ensure proper airflow within the PC case.
- Proper Handling: Always handle the motherboard by its edges to avoid touching sensitive components or pins. Use anti-static precautions when handling.
- CMOS Battery: The CMOS battery powers the BIOS settings when the system is off. If settings are lost frequently, the battery may need replacement.
- BIOS Updates: Only update the BIOS if necessary and follow official instructions carefully. Incorrect updates can cause irreversible damage.
4. Troubleshooting
If you encounter issues with your system, refer to the following troubleshooting steps:
4.1 Can't Boot (No response, no fan rotation, no indicator light)
- Clear the CMOS jumper (refer to Section 2.3).
- Check if the CPU is compatible with the motherboard.
- Verify that the motherboard's power and CPU power supply cables are properly plugged in.
- Ensure the system panel power-on cable is correctly connected.
- Check if the power supply unit is functioning correctly.
- Remove non-essential devices (graphics card, hard disk, USB devices) and attempt to boot.
- If possible, try replacing the CPU with a known working one.
4.2 Start-up and then Shutdown (Fan rotates briefly, then system shuts down)
- Clear the CMOS jumper.
- Verify CPU compatibility.
- Check if the CPU is damaged; replace if necessary.
- Replace memory modules.
- Remove non-essential devices (graphics card, hard drive, USB devices) and test again.
4.3 Computer Keeps Restarting (Reboot loop)
- Clear the CMOS jumper.
- Check if the CPU is compatible with the motherboard.
- Check if the CPU is defective; replace if necessary.

- Replace CPU.
- Replace memory.
State 2: Fan rotating, Caps Lock key responsive.
- Check if the monitor is turned on.
- Check if the monitor display cable (DP, HDMI, DVI, VGA) is securely plugged in.
- If using a CPU without integrated graphics (e.g., Intel Xeon series or 'F' suffix CPUs), ensure a dedicated graphics card is installed.
- Verify the display data cable is connected to the correct port: to the motherboard's display interface if no discrete graphics card, or to the discrete graphics card's interface if one is installed.
- Replace the data cable connected to the monitor.
- Replace the graphics card.
4.5 Blue Screen or Crash
- Check motherboard heat dissipation (CPU cooling fan working, cooler tightly fitted, thermal paste applied).
