3.4. Expansion Card Installation

The motherboard includes one PCIE x16 graphics card slot and one PCIE x1 slot.

1. Locate PCIe Slot: Identify the appropriate PCIe slot for your expansion card (e.g., graphics card in the PCIE x16 slot).
2. Insert Card: Align the card with the slot and press down firmly until it is fully seated.
3. Secure Card: Secure the card to the chassis with a screw.

3.5. Power Supply Connection

Connect the power cables from your Power Supply Unit (PSU) to the motherboard.

1. 24-pin ATX Power: Connect the main 24-pin ATX power connector from the PSU to the corresponding socket on the motherboard.
2. 8-pin CPU Power: Connect the 8-pin CPU power connector (EPS12V) from the PSU to the socket near the CPU.

3.6. Front Panel & I/O Connections

Connect your case's front panel connectors and external peripherals to the motherboard's I/O ports.

• Front Panel Headers: Connect the power switch, reset switch, HDD LED, and power LED connectors from your case to the front panel header pins. Refer to the motherboard's silkscreen for correct pin assignments.
• USB Headers: Connect your case's front USB 2.0 and USB 3.0 ports to the corresponding USB headers on the motherboard (1 set USB3.0 pins, 1 set USB2.0 pins).
• Audio Header: Connect the front panel audio cable to the audio header.
• Rear I/O Ports: Connect peripherals such as keyboard (PS/2), mouse (PS/2), monitor (VGA, HD Multimedia), network cable (RJ45), and USB devices (6 x USB 2.0, 2 x USB 3.0) to the rear I/O panel.

Regularly clean your computer's interior to prevent dust buildup, which can lead to overheating and component failure. Use compressed air to remove dust from heatsinks, fans, and other components. Ensure the system is powered off and unplugged before cleaning.

5.2. BIOS/Firmware Updates

Periodically check the manufacturer's website for updated BIOS/firmware versions. BIOS updates can improve system stability, add support for new hardware, or fix bugs. Follow the manufacturer's instructions carefully when performing a BIOS update to avoid system damage.

6. Troubleshooting

This section addresses common issues you might encounter.

6.1. No Power/No Boot

• Verify all power cables (24-pin ATX, 8-pin CPU) are securely connected to the motherboard and PSU.
• Ensure the PSU is switched on and connected to a working power outlet.
• Check front panel power switch connection to the motherboard.
• Test the PSU with another system or a PSU tester if available.

6.2. No Display

• Ensure the monitor is connected to the correct graphics output (either integrated or discrete graphics card).
• Reseat the graphics card and ensure its power connectors are attached (if applicable).
• Try a different monitor or display cable.
• If using integrated graphics, ensure your CPU supports it.

6.3. Memory Issues

• Ensure all RAM modules are fully seated in their slots.
• Try booting with only one RAM module installed, testing each module individually.
• Verify RAM compatibility with the motherboard and CPU.

6.4. Storage Detection Problems

• Check SATA data and power cable connections for all drives.
• Ensure M.2 SSD is properly seated and secured.
• Verify SATA mode (AHCI/RAID) settings in BIOS/UEFI.
• Check if the M.2 slot jumper switch is set correctly for NVME or NGFF.
