4.2. CPU Installation

1. Locate the LGA1155 CPU socket on the motherboard (refer to Figure 3.3).
2. Open the CPU socket lever and lift the metal retention plate.
3. Carefully align the CPU with the socket, ensuring the gold triangle on the CPU matches the triangle on the socket. Do not force the CPU into place.
4. Lower the retention plate and secure it with the lever.
5. Apply a thin, even layer of thermal paste to the top of the CPU (if not pre-applied to the cooler).
6. Install the CPU cooler according to its manufacturer's instructions.

4.3. Memory (RAM) Installation

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

4.4. Storage Device Installation

1. Connect your SATA storage devices (HDDs/SSDs) to the SATA 3.0 or SATA 2.0 ports on the motherboard using SATA data cables (refer to Figure 3.2).
2. Connect the SATA power cables from your power supply to the storage devices.

4.5. Power Connections

1. Connect the 24-pin ATX main power connector from your power supply to the corresponding port on the motherboard.
2. Connect the 4-pin or 8-pin CPU power connector (EPS12V) from your power supply to the CPU power port near the CPU socket.

4.6. Graphics Card Installation (Optional)

1. Locate the PCIe x16 slot on the motherboard.
2. Remove the corresponding expansion slot cover from your computer case.
3. Align the graphics card with the PCIe slot and press down firmly until it is seated correctly and the retention clip locks.
4. Secure the graphics card to the case with a screw.
5. Connect any necessary PCIe power cables from your power supply to the graphics card.

4.7. Front Panel Connections

Connect the front panel cables (power button, reset button, USB ports, audio jacks, power LED, HDD LED) from your computer case to the corresponding headers on the motherboard. Refer to the structural diagram (Figure 3.2) for header locations.

5. Operating Instructions

5.1. First Boot

1. After completing all hardware connections, connect your monitor, keyboard, and mouse.
2. Plug in the power cord and turn on your power supply.
3. Press the power button on your computer case.
4. The system should power on and display the BIOS/UEFI splash screen.

5.2. BIOS/UEFI Configuration

To enter the BIOS/UEFI setup utility, press the DEL or F2 key during the boot process (before the operating system loads). In the BIOS/UEFI, you can configure system settings such as boot order, date/time, and hardware parameters.

5.3. Operating System and Driver Installation

1. Install your preferred operating system (e.g., Windows 10) from a bootable USB drive or DVD.
2. After the operating system is installed, install the necessary drivers for the motherboard components (chipset, audio, LAN, etc.). These drivers are typically provided on a driver CD or can be downloaded from the manufacturer's website.
