4.2 Pre-Installation Checklist

• Ensure you have a compatible AM3 socket CPU.
• Acquire DDR3 RAM modules (1600/1333/1066MHz).
• Prepare a compatible ATX power supply.
• Gather necessary tools (screwdriver, anti-static wrist strap).

4.3 Installation Steps

1. Prepare the Case: Install the I/O shield into the rear opening of your computer case.
2. Install the CPU: Carefully open the CPU socket lever. Align the CPU with the socket, ensuring the golden triangle on the CPU matches the marking on the socket. Gently place the CPU into the socket without force. Close the lever to secure the CPU.
3. Install the CPU Cooler: Follow the cooler manufacturer's instructions to install the CPU cooler onto the motherboard.
4. Install RAM: Open the clips on the DDR3 memory slots. Align your DDR3 RAM modules with the slots, ensuring the notch on the module matches the notch in the slot. Press down firmly on both ends until the clips snap into place.

5. Mount the Motherboard: Carefully place the motherboard into the computer case, aligning the screw holes with the standoffs. Secure the motherboard with screws.
6. Connect Power: Connect the 24-pin ATX power connector and the 4-pin CPU power connector from your power supply to the corresponding ports on the motherboard.
7. Connect Storage Devices: Use the provided SATA cable to connect your SATA 3.0 storage devices (HDD/SSD) to the SATA ports on the motherboard.
8. Connect Front Panel Cables: Connect the front panel headers (power button, reset button, USB ports, audio jacks, LED indicators) from your case to the corresponding pins on the motherboard. Refer to your case manual for pin assignments.
9. Install Expansion Cards: If using a dedicated graphics card or other PCIe expansion cards, insert them into the PCIe X16 slot and secure them.
10. Connect Peripherals: Connect your keyboard, mouse, monitor (VGA or HDMI), and Ethernet cable to the rear I/O ports.

5. Operating Instructions

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

5.1 First Boot

• Press the power button on your computer case.
• The system should power on, and you should see a display on your monitor.
• Access the BIOS/UEFI setup (usually by pressing DEL or F2 during boot) to configure boot order, system time, and other settings.
• Install your operating system from a bootable USB drive or DVD.

5.2 Driver Installation

After installing the operating system, install the necessary drivers for the motherboard's integrated components (chipset, graphics, audio, network). These drivers are typically provided on a CD/DVD with the motherboard or can be downloaded from the PUSOKEI support website.

5.3 High-Definition Multimedia Experience

6. Maintenance

Proper maintenance can extend the lifespan and ensure stable operation of your motherboard.

• Keep it Clean: Regularly clean dust from inside your computer case using compressed air. Dust accumulation can lead to overheating.
• Ensure Proper Airflow: Make sure your computer case has adequate ventilation and that fans are functioning correctly to prevent heat buildup.
• BIOS Updates: Periodically check the manufacturer's website for BIOS updates. Updates can improve stability, compatibility, and performance. Follow update instructions carefully.
• Component Checks: Ensure all cables are securely connected and that no components are loose.

7. Troubleshooting

If you encounter issues with your motherboard, refer to the following common troubleshooting steps.

7.1 No Power / No Display

• Check Power Connections: Ensure the 24-pin ATX and 4-pin CPU power connectors are firmly seated.
• Verify Power Supply: Test your power supply unit (PSU) to ensure it is functional.
• Reseat Components: Remove and re-install RAM modules, graphics card (if applicable), and CPU to ensure they are properly seated.
• Clear CMOS: Refer to the motherboard manual for instructions on how to clear the CMOS (Complementary Metal-Oxide-Semiconductor) settings, which can resolve boot issues. This usually involves removing the CR2032L battery for a few minutes or using a jumper.
• Test with Minimal Components: Disconnect all non-essential components (e.g., extra drives, expansion cards) and try booting with only the CPU, one RAM stick, and the necessary power connections.

7.2 System Instability / Crashes

• Check Temperatures: Monitor CPU and motherboard temperatures. Overheating can cause instability. Ensure proper cooling.
• Test RAM: Use memory diagnostic tools to check for faulty RAM modules.
• Update Drivers: Ensure all motherboard and component drivers are up to date.
• Check PSU: An insufficient or failing power supply can cause instability.

7.3 Peripheral Issues (USB, Audio, Network)

• Install/Update Drivers: Ensure the latest drivers for these components are installed.
• Check Connections: Verify that internal headers (for front panel USB/audio) and external cables are securely connected.
• BIOS Settings: Check BIOS settings to ensure integrated peripherals are enabled.
