4. Setup and Installation
Before beginning installation, ensure your workspace is clean, well-lit, and static-free. It is recommended to wear an anti-static wrist strap to prevent damage to components.
4.1. CPU Installation
- Locate the LGA 2011-3 CPU socket on the motherboard.
- Gently push down the load lever and pull it away from the socket to open the CPU retention frame.
- 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.
- Lower the CPU into the socket. Close the retention frame and secure it with the load lever.
- Apply thermal paste to the CPU and install the CPU cooler according to its manufacturer's instructions.

4.3. Storage Device Installation (SATA & M.2)
- SATA Drives: Connect SATA data cables from your storage drives (HDDs/SSDs) to the SATA 2.0 ports on the motherboard. Connect SATA power cables from your power supply to the drives.
- M.2 NVME SSD: Locate the M.2 slot. Insert the M.2 SSD at a 30-degree angle, then gently push it down and secure it with the provided screw. Ensure the jumper switch for the M.2 interface is set correctly for Serial ATA or PCIE mode as required by your M.2 device.

4.4. Power Connections
- Connect the 24-pin ATX power connector from your power supply to the main power socket on the motherboard.
- Connect the 8-pin CPU power connector (EPS12V) from your power supply to the CPU power socket near the CPU.
4.5. Front Panel and I/O Connections
- Connect the front panel headers (power switch, reset switch, HDD LED, power LED) to their respective pins on the motherboard. Refer to the motherboard's silkscreen labels for correct orientation.
- Connect USB 2.0 and USB 3.0 front panel cables to the corresponding USB headers.
- Connect the audio front panel cable to the audio header.
- Install your graphics card into the PCIE x16 slot and secure it.

7. Troubleshooting
- No Power: Ensure all power cables (24-pin ATX, 8-pin CPU) are securely connected to the motherboard and power supply. Verify the power supply switch is on.
- No Display: Check that the monitor is connected to the graphics card (not the motherboard's I/O if a dedicated GPU is installed). Reseat the graphics card and RAM modules.
- System Instability/Crashes: This can be caused by incompatible RAM, insufficient power, or overheating. Verify RAM compatibility and seating. Check CPU cooler installation and fan operation.
- Peripheral Not Detected: Ensure USB devices are properly connected. Try different USB ports. Check for necessary drivers.
- BIOS Reset: If system settings become unstable, you can clear the CMOS by removing the CR2032 battery for a few minutes or using the CMOS clear jumper (refer to motherboard diagram for location).
8. Maintenance
- Cleaning: 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 the update instructions carefully to avoid damaging the motherboard.
- Cable Management: Ensure cables are neatly routed to improve airflow and prevent interference.
