4.3 Component Installation
- CPU Installation: Carefully 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 without forcing it. Close the lever to secure the CPU.
- CPU Cooler Installation: Apply thermal paste to the CPU if not pre-applied on the cooler. Mount the CPU cooler according to its manufacturer's instructions, ensuring it is securely fastened and the fan cable is connected to the CPU_FAN header.
- RAM Installation: Open the clips on both ends of the DDR4 DIMM slots. Align the notch on the memory module with the key in the slot. Press down firmly on both ends of the module until the clips snap into place. Install modules in matching slots for dual-channel operation (e.g., DDR4_1 and DDR4_2).
- M.2 SSD Installation: Locate the M.2 slot. Insert the M.2 SSD at an angle into the slot. Push it down and secure it with the provided screw.
- Graphics Card (PCIe) Installation: Open the retention clip on the PCIe x16 slot. Align the graphics card with the slot and press down firmly until it is seated. Ensure the retention clip locks into place. Secure the card to the case with a screw.
- SATA Device Connection: Connect SATA data cables from your storage devices (HDD/SSD) to the SATA 6Gb/s ports on the motherboard. Connect SATA power cables from your power supply to the devices.
- Power Supply Connection: Connect the 24-pin ATX main power connector and the 8-pin ATX 12V CPU power connector from your power supply to the corresponding ports on the motherboard.
- Front Panel Header Connection: Connect the power switch, reset switch, HDD LED, and front panel USB/audio cables to their respective headers on the motherboard. Refer to the motherboard layout for exact locations.
- Mounting the Motherboard: Install the I/O shield into your computer case. Carefully place the motherboard into the case, aligning the screw holes with the standoffs. Secure the motherboard with screws.
5. Operating Instructions
5.1 Initial Boot-up
After all components are installed and connected, power on your system. The system should display the GIGABYTE splash screen. If no display appears, refer to the Troubleshooting section.
5.2 BIOS/UEFI Setup
To enter the BIOS/UEFI setup, press the DEL key during the initial boot-up. The GIGABYTE UEFI Dual BIOS allows you to configure system settings, boot order, and monitor hardware status. Save changes before exiting.
5.3 Driver Installation
After installing your operating system, install the necessary drivers for the motherboard components. Use the provided driver CD or download the latest drivers from the official GIGABYTE website (www.gigabyte.com) for optimal performance and compatibility.
5.4 Operating System Installation
Insert your operating system installation media (USB drive or DVD) and configure the boot order in the BIOS/UEFI to boot from the media. Follow the on-screen instructions to install your preferred operating system.
6. Maintenance
- Dust Removal: Regularly clean the interior of your computer case to prevent dust buildup, which can lead to overheating. Use compressed air to gently remove dust from fans, heatsinks, and motherboard components.
- BIOS Updates: Periodically check the GIGABYTE website for BIOS updates. BIOS updates can improve system stability, add support for new hardware, or fix known issues. Follow the update instructions carefully to avoid system damage.
- Driver Updates: Keep your device drivers updated to ensure optimal performance and compatibility with your operating system and applications. Download drivers only from the official GIGABYTE website or component manufacturers.
7. Troubleshooting
If you encounter issues, consider the following common troubleshooting steps:
- No Power: Ensure all power cables (24-pin ATX, 8-pin CPU, GPU PCIe power) are securely connected. Verify the power supply switch is in the ON position.
- No Display: Check that your monitor is connected to the correct video output on the graphics card or motherboard. Reseat the graphics card and RAM modules. Try booting with only one RAM stick.
- System Instability/Crashes: This can be caused by loose components, overheating, or incompatible drivers. Check all connections, monitor temperatures, and ensure all drivers are up-to-date.
- Boot Loop: If the system repeatedly restarts, try clearing the CMOS. Locate the CLR_CMOS jumper or remove the CMOS battery for a few minutes, then reinstall.
- Component Not Detected: Verify that the component (e.g., M.2 SSD, SATA drive) is correctly installed and connected. Check BIOS settings to ensure it is enabled.
For more complex issues, consult the detailed troubleshooting section in the full user manual available on the GIGABYTE website or contact GIGABYTE technical support.
