3. Operating Instructions

Once all components are installed and connected, you can power on your system.

3.1 Initial Boot-up

1. Ensure all power cables are securely connected.
2. Press the power button on your computer case.
3. The system should boot up and display the BIOS/UEFI splash screen.
4. If no display appears, refer to the Troubleshooting section.

3.2 BIOS/UEFI Access

To access the BIOS/UEFI setup utility, press the designated key (commonly DEL or F2) repeatedly during the initial boot-up sequence. From the BIOS/UEFI, you can configure system settings, boot order, and monitor hardware status.

3.3 Operating System Installation

After configuring the BIOS/UEFI, you can proceed with installing your preferred operating system (e.g., Windows, Linux) from a bootable USB drive or DVD.

4. Maintenance

Proper maintenance ensures the longevity and optimal performance of your motherboard.

• Dust Removal: Regularly clean dust from the motherboard and components using compressed air. Ensure the system is powered off and unplugged before cleaning.
• BIOS/UEFI Updates: Periodically check the manufacturer's website for BIOS/UEFI updates. Updates can improve stability, compatibility, and performance. Follow update instructions carefully to avoid system damage.
• Component Checks: Ensure all cables and components are securely seated. Loose connections can cause instability.
• CMOS Battery: The motherboard uses a CR2032 button cell battery (not included) for CMOS settings. If your system frequently loses time or BIOS settings, the battery may need replacement.

5. Troubleshooting

This section provides solutions to common issues you might encounter.

5.1 No Power / System Does Not Turn On

• Check if the power supply unit (PSU) is properly connected to the wall outlet and the motherboard (24-pin ATX and 4-pin ATX 12V).
• Ensure the power button cable from the case is correctly connected to the motherboard's front panel header.
• Test the PSU with another system or a PSU tester if available.

5.2 No Display on Monitor

• Verify that the monitor is powered on and the video cable is securely connected to the motherboard's VGA or HD multimedia interface port.
• Reseat the RAM module(s). Incorrectly seated RAM is a common cause of no display.
• Ensure the CPU is correctly installed and the CPU cooler is properly seated.
• If using a dedicated graphics card (via PCIe), ensure it is properly seated and powered, and connect the monitor to the graphics card's output.

5.3 System Instability / Random Crashes

• Check for overheating. Ensure CPU cooler and case fans are functioning correctly.
• Run memory diagnostic tools to check for faulty RAM.
• Ensure all drivers (chipset, graphics, etc.) are up to date.
• Check for loose power or data cables to storage devices.

5.4 Peripherals Not Detected

• Try connecting the peripheral to a different USB port.
• Ensure the peripheral's drivers are installed.
• Check BIOS/UEFI settings to ensure USB ports are enabled.
