4. Setup and Installation

4.1 CPU Installation

1. Locate the LGA 775 CPU socket.
2. Gently push down the load lever and pull it to the side to open the socket retention frame.
3. Carefully align the CPU with the socket, ensuring the notches on the CPU match the keys on the socket. Do not force the CPU into the socket.
4. Lower the CPU into the socket.
5. Close the retention frame and push the load lever back into its locked position.
6. Apply a thin, even layer of thermal paste to the top of the CPU.
7. Install the CPU cooler according to its manufacturer's instructions, ensuring it is securely fastened and its fan is connected to the CPU_FAN header on the motherboard.

4.2 RAM Installation

1. Open the clips at both ends of the DDR3 DIMM slots.
2. Align the memory module with the slot, ensuring the notch on the module matches the key in the slot.
3. Press down firmly on both ends of the memory module until the clips snap into place.

4.3 Expansion Card Installation

1. Remove the metal bracket cover from the desired expansion slot on your computer case.
2. Align the expansion card with the slot (PCIe x16 or PCI).
3. Press down firmly until the card is fully seated in the slot.
4. Secure the card with a screw or retention clip to the computer case.

4.4 Connecting Storage Devices

1. Connect one end of a SATA data cable to a SATA port on the motherboard.
2. Connect the other end of the SATA data cable to your HDD or SSD.
3. Connect a SATA power cable from your power supply to the HDD or SSD.

4.5 Power Supply Connections

1. Connect the 24-pin ATX power connector from your power supply to the corresponding header on the motherboard.
2. Connect the 4-pin ATX 12V power connector from your power supply to the corresponding header near the CPU socket.

4.6 Front Panel and I/O Connections

• Connect the front panel connectors (Power SW, Reset SW, HDD LED, Power LED) to the F_PANEL header according to the pin assignments. Refer to your computer case manual for specific pinouts.
• Connect front panel USB ports to the USB headers on the motherboard.
• Connect front panel audio ports to the F_AUDIO header.
• Connect peripherals (monitor, keyboard, mouse, etc.) to the rear I/O panel ports.

5. Operating Instructions

5.1 First Boot

1. After all components are installed and connected, ensure the power supply is switched on.
2. Press the power button on your computer case.
3. The system should power on, and you should see a display on your monitor.
4. If no display appears, refer to the Troubleshooting section.

5.2 BIOS/UEFI Setup

To enter the BIOS/UEFI setup utility, press the DEL or F2 key repeatedly during the initial boot sequence (POST). The exact key may vary; observe the on-screen prompts.

• Boot Order: Configure the boot order to install your operating system from a USB drive or optical drive.
• System Time/Date: Set the correct system time and date.
• SATA Mode: Ensure the SATA controller mode (e.g., AHCI) is correctly set for your operating system and storage devices.
• Save and Exit: Always save your changes before exiting the BIOS/UEFI setup.

5.3 Driver Installation

After installing your operating system, install the necessary drivers for the motherboard's components. These typically include chipset drivers, integrated graphics drivers, LAN drivers, and audio drivers. Drivers are usually provided on a support CD or can be downloaded from the chipset manufacturer's website.

6. Maintenance

• Dust Removal: Regularly clean dust from inside your computer case, especially from CPU coolers, case fans, and heatsinks, using compressed air. Ensure the system is powered off and unplugged before cleaning.
• BIOS Updates: Check the manufacturer's website periodically for BIOS updates. BIOS updates can improve system stability, compatibility, and performance. Follow the update instructions carefully to avoid damaging the motherboard.
• Cable Management: Ensure internal cables are neatly routed to improve airflow and prevent interference.

7. Troubleshooting
