4.2 Component Installation Steps
- Install the CPU: Carefully open the CPU socket lever. Align the triangular mark on the CPU with the mark on the socket and gently place the CPU into the socket. Close the lever to secure the CPU. Do not force the CPU into the socket.
- Install the CPU Cooler: Apply thermal paste (if not pre-applied) and mount the CPU cooler according to its specific instructions. Ensure it is securely fastened.
- Install Memory (RAM): Open the clips on the DDR4 DIMM slots. Align the notch on the RAM module with the key in the slot. Press down firmly on both ends of the module until the clips snap into place. Refer to the motherboard manual for recommended dual-channel configurations.
- Mount the Motherboard: Install the I/O shield into your computer case. Align the motherboard with the standoffs in the case and secure it with screws. Ensure the screw mounting holes are aligned properly.
- Connect Power Supply: Connect the 24-pin ATX main power connector and the 8-pin ATX 12V power connector from your power supply to the motherboard. Ensure both are fully seated.
- Install Storage Devices: Connect SATA data cables from your storage drives (HDDs/SSDs) to the SATA ports on the motherboard. Connect power cables from the power supply to the drives. If using an M.2 SSD, install it into the M.2 slot and secure it with the provided screw.
- Install Expansion Cards: Insert your graphics card into the primary PCIe x16 slot. Secure it with the case screw. Install any other expansion cards (e.g., Wi-Fi card) into the appropriate PCIe slots.
- Connect Front Panel Cables: Connect the power button, reset button, HDD LED, power LED, and USB/audio headers from your case to the corresponding pins on the motherboard. Refer to the motherboard's detailed manual for pin assignments.

- No Display:
- Ensure the monitor is connected to the graphics card (or integrated graphics port) and powered on.
- Check if the graphics card is properly seated in its PCIe slot and has adequate power.
- Verify RAM modules are correctly installed in their slots. Try reseating them or testing with one module at a time.
- Confirm the 24-pin and 8-pin power connectors are fully seated on the motherboard.
- System Fails to Boot:
- Check all power connections to the motherboard, CPU, and graphics card.
- Ensure the CPU is correctly installed and the cooler is properly mounted.
- Disconnect all non-essential peripherals and storage devices to isolate the issue.
- Try clearing the CMOS (BIOS settings) by removing the CMOS battery for a few minutes or using the CLR_CMOS jumper (refer to the detailed manual for location).
- Unstable System/Crashes:
- Ensure all drivers are up to date.
- Check CPU and GPU temperatures to rule out overheating.
- Run memory diagnostic tools to check for faulty RAM.
