1. Step 1: Press down on the lever located next to the CPU socket and gently lift it to open the CPU retention frame.
2. Step 2: Open the CPU cover.
3. Step 3: Carefully align the triangle symbols on the CPU and the socket. Gently place the CPU into the socket without forcing it.
4. Step 4: Remove the CPU plastic cover (if present) after the CPU is seated.
5. Step 5: Align the groove with the screw hole and lower the lever to secure the CPU in place.

Important: Do not touch the CPU contacts with your hands. Do not touch the CPU pins on the motherboard. Improper handling can cause damage.

1.4 Expansion Cards

The motherboard includes:

• 1 x PCI Express x16 slot for graphics cards.
• 1 x PCI Express x1 slot for other expansion cards.

Insert expansion cards firmly into their respective slots until they are fully seated and secured with the case's retention mechanism.

1.5 Power Connection

Connect the 24-pin ATX power connector and the 4-pin CPU power connector from your power supply unit (PSU) to the corresponding sockets on the motherboard. Ensure connections are secure to maintain circuit reliability.

1.6 Connecting Peripherals

Connect your monitor, keyboard, mouse, and other peripherals to the appropriate ports on the motherboard's rear I/O panel.

2. Operating Instructions

2.1 Initial Boot-up

After all components are installed and connected, power on your system. The system should initiate the Power-On Self-Test (POST) and display the BIOS/UEFI splash screen.

2.2 BIOS/UEFI Access

To enter the BIOS/UEFI setup utility, press the designated key (usually Del or F2) during the POST sequence. Here you can configure system settings, boot order, and monitor hardware status.

2.3 Operating System Installation

Insert your operating system installation media (USB drive or DVD) and configure the boot order in BIOS/UEFI to boot from the installation media. Follow the on-screen prompts to install your operating system.

2.4 Driver Installation

After installing the operating system, install the necessary drivers for the motherboard chipset, audio, LAN, and any other integrated components. Drivers are typically provided on a support CD or can be downloaded from the manufacturer's website.

2.5 Video Output

The motherboard supports 1080p HD video output via VGA and HDMI ports, provided your CPU supports integrated graphics. This allows for high-definition display without a dedicated graphics card.

3. Maintenance

Regular maintenance helps ensure the longevity and stable operation of your motherboard and system.

• Dust Removal: Periodically clean dust from inside your computer case, especially from heatsinks and fans, using compressed air. Ensure the system is powered off and unplugged before cleaning.
• BIOS Updates: Check the manufacturer's website for BIOS/UEFI updates. Updates can improve compatibility, stability, and performance. Follow the update instructions carefully to avoid system damage.
• Component Checks: Ensure all cables and components are securely seated. Loose connections can lead to instability.

4. Troubleshooting

If you encounter issues, refer to the following common troubleshooting steps:

• No Power:
  • Check if the power supply unit (PSU) is connected correctly and switched on.
  • Ensure the 24-pin and 4-pin power connectors are firmly seated on the motherboard.
  • Verify the power button cable from the case is correctly connected to the motherboard's front panel header.
• No Display:
  • Ensure the monitor is connected to the correct video output port (VGA or HDMI) and is powered on.
  • If using a dedicated graphics card, ensure it is properly seated in the PCIe x16 slot and has auxiliary power connected (if required).
  • If your CPU has integrated graphics, try connecting the monitor to the motherboard's video output ports directly.
  • Reseat RAM modules.
• System Instability/Crashes:
  • Check for proper CPU and GPU cooling.
  • Ensure RAM modules are compatible and correctly installed.
  • Update drivers and BIOS/UEFI to the latest versions.
  • Test components individually if possible.
• Storage Not Detected:
  • Verify SATA data and power cables are securely connected to both the drive and the motherboard.
  • For M.2 drives, ensure it is correctly seated and secured. Check BIOS settings for M.2 mode (NVMe/SATA).

If problems persist, consult the Denash support website or contact your retailer for further assistance.
