4. Lower the load plate and push the lever back into place until it clicks.
5. Apply a thin, even layer of thermal paste to the CPU (if not pre-applied to the cooler).
6. Install the CPU cooler according to its manufacturer's instructions.

4.3 RAM Installation

1. Locate the two DDR3 DIMM slots (refer to Figure 3.2).
2. Open the clips at both ends of the memory slot.
3. Align the notch on the DDR3 memory module with the notch in the DIMM slot.
4. Press down firmly on both ends of the memory module until the clips snap into place.

4.4 Storage Device Installation (SATA & M.2)

1. SATA Drives: Connect one end of a SATA data cable to a SATA2.0 port on the motherboard and the other end to your HDD/SSD. Connect a SATA power cable from your power supply to the drive.
2. M.2 NVMe SSD: Insert the M.2 SSD into the M.2 slot at a 30-degree angle. Push it down and secure it with the provided screw.

4.5 Graphics Card and Expansion Card Installation

1. Locate the PCIe x16 slot for your graphics card (refer to Figure 3.2).
2. Open the retention clip at the end of the slot.
3. Align the graphics card with the slot and press down firmly until it is seated and the clip snaps shut.
4. Secure the card to the PC case with a screw.
5. For other expansion cards, use the PCIe x1 slot similarly.

4.6 Power Supply Connections

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

4.7 Front Panel and Peripheral Connections

• Connect the front panel headers (power switch, reset switch, HDD LED, power LED) to the corresponding pins on the motherboard. Refer to your PC case manual for pin assignments.
• Connect front panel USB 2.0 and USB 3.0 cables to their respective headers.
• Connect the front panel audio cable to the audio header.
• Connect external peripherals (monitor, keyboard, mouse, etc.) to the back I/O panel ports.

5. Operating Instructions

5.1 First Boot

1. After all components are installed and connected, ensure your monitor is connected and powered on.
2. Connect the power cord to your power supply and turn on the power supply switch.
3. Press the power button on your PC case.
4. The system should power on, and you should see the BIOS/UEFI splash screen.

5.2 BIOS/UEFI Setup

• To enter the BIOS/UEFI setup utility, press the DEL or F2 key repeatedly during the boot process.
