2. Setup and Installation
2.1. Before You Begin
- Ensure you have a compatible 8th Generation Intel Core processor (LGA 1151 socket).
- Prepare necessary components: CPU, CPU cooler, DDR4 RAM, graphics card (if not using integrated graphics), storage devices (SSD/HDD), power supply unit (PSU), and PC case.
- Always handle the motherboard by its edges to avoid static discharge. Consider using an anti-static wrist strap.
- Unplug the power cord from the wall outlet before installing or removing any components.
2.2. Component Installation
Follow these steps for installing core components onto your motherboard:
- CPU Installation: Open the CPU socket lever, align the triangular mark on the CPU with the mark on the socket, gently place the CPU into the socket, and close the lever to secure it.
- CPU Cooler Installation: Install your CPU cooler according to its manufacturer's instructions. Ensure proper thermal paste application.
- RAM Installation: Open the clips on the DDR4 DIMM slots. Align the notch on the RAM module with the notch in the slot. Press down firmly on both ends of the module until the clips snap into place. For dual-channel performance, install RAM modules in matching colored slots (e.g., DDR4_1 and DDR4_2).
- Graphics Card (PCIe) Installation: Open the retention clip on the PCIe x16 slot. Align your graphics card with the slot and press down firmly until it is seated. Close the retention clip.
- Storage Device (SATA) Connection: Connect your SATA SSDs or HDDs to the SATA 6Gb/s ports on the motherboard using SATA data cables. Connect the power cables from your PSU to the storage devices.

2.3. Connecting Peripherals and Power
- Power Connections: Connect the 24-pin ATX main power connector and the 8-pin ATX 12V CPU power connector from your PSU to the corresponding ports on the motherboard.
- Front Panel Connectors: Connect the power button, reset button, HDD LED, and power LED cables from your PC case to the front panel header (F_PANEL) on the motherboard. Refer to the detailed pinout diagram in the full PDF manual for correct orientation.
- USB and Audio Headers: Connect front panel USB 2.0, USB 3.0, and audio cables to their respective headers on the motherboard.
- Rear I/O Panel Connections: Connect your keyboard, mouse, monitor (via HDMI, DVI-D, or VGA), Ethernet cable, and audio devices to the ports on the rear I/O panel.

3. Operating Your System
3.1. First Boot and BIOS Setup
After assembling your system, connect your monitor, keyboard, and mouse. Power on your system. The system should display the GIGABYTE splash screen. Press the DEL key during startup to enter the BIOS (Basic Input/Output System) setup. Here you can configure boot order, system time, and other hardware settings.
- Boot Order: Ensure your primary storage device (where the operating system will be installed) is set as the first boot device.
- XMP Profile: If using high-speed DDR4 RAM, enable the XMP (Extreme Memory Profile) in the BIOS to achieve the advertised memory speeds.
- Save and Exit: After making changes, save your settings and exit the BIOS. The system will restart.
3.2. Operating System and Driver Installation
Install your preferred operating system (e.g., Windows 10) from a USB drive or optical media. After the OS installation, install the necessary drivers for your motherboard components. These drivers are typically found on the GIGABYTE support website for your specific model.
- Chipset Drivers: Essential for proper communication between the CPU and other motherboard components.
- LAN Driver: Required for network connectivity.
- Audio Driver: For sound output and input.
- USB Drivers: While Windows 10 generally has native USB 3.0 support, installing the latest GIGABYTE drivers is recommended for optimal performance.
- GIGABYTE APP Center: Install the GIGABYTE APP Center to access utilities like EasyTune for system optimization, @BIOS for BIOS updates, and RGB Fusion for lighting control (if applicable).
4. Maintenance
4.1. System Cleaning
- Regularly clean dust from inside your PC case, especially around fans and heatsinks, using compressed air.
- Ensure the system is powered off and unplugged before cleaning.
- Avoid using liquid cleaners directly on components.
4.2. Driver and BIOS Updates
- Periodically check the GIGABYTE website for updated drivers and BIOS versions.
- BIOS updates can improve system stability, add support for new hardware, or fix bugs. Always follow the official update procedure carefully to avoid damaging the motherboard.
5. Troubleshooting
5.1. Common Issues and Solutions
- No Display/Boot:
- Check all power connections (24-pin ATX, 8-pin CPU, GPU power).
- Reseat RAM modules. Try booting with only one RAM stick.
- Ensure the monitor cable is securely connected to the graphics card or motherboard.
- If using an external graphics card, ensure the BIOS CSM (Compatibility Support Module) setting is enabled if your BIOS version is older than F5. Some older BIOS versions (e.g., F2) may not boot with an external GPU without this setting.
- USB Devices Not Working (Windows 7):
- The B360M DS3H motherboard's USB ports, including 2.0, operate on a USB 3.0 base. Windows 7 has limited native support for USB 3.0.
- It is highly recommended to use Windows 10 or a newer operating system for full compatibility and driver support.
- If you must use Windows 7, you will need to integrate USB 3.0 drivers into your Windows 7 installation media or use a PS/2 keyboard/mouse (if available) to install drivers after OS installation.
- CPU Fan Alarm:
- If you hear a continuous alarm, check if a CPU fan is properly connected to the CPU_FAN header.
- Ensure "fan fail/stop alarm" settings in the BIOS are configured correctly or disabled if no fan is connected to a monitored header.
- PCIe x1 Slot Covered by GPU:
- Due to the proximity of the PCIe x1 slot to the PCIe x16 slot, a large graphics card may obstruct the x1 slot.
- Consider using a PCIe x1 to x16 riser cable or installing your x1 card in another available PCIe slot if compatible.
- System Instability/Crashes:
- Ensure all drivers are up to date.
- Check RAM for errors using memory diagnostic tools.
- Monitor CPU and GPU temperatures to prevent overheating.
