For wireless network, ensure the WiFi antennas are installed. You can then connect to WiFi networks through your operating system settings.
8. Troubleshooting
- No Display: Ensure monitor cables are securely connected to the graphics card or motherboard (if using integrated graphics). Check if the monitor is powered on and set to the correct input.
- System Fails to Boot: Verify all power cables (24-pin ATX, 8-pin CPU) are firmly connected. Re-seat RAM modules and expansion cards. Ensure CPU is correctly installed.
- BIOS Reset: If you encounter issues after changing BIOS settings, you can reset the BIOS to default settings. Disconnect the AC power, then press and hold the CLR_CMOS button on the rear I/O panel for 3-5 seconds.
- Network Connectivity Issues: Check the RJ45 indicator lights (refer to section 7.3). Ensure network drivers are installed. For WiFi, confirm antennas are attached and drivers are installed.
- Motherboard Shut Down/Stopped Working: Ensure a stable and sufficient power supply. Verify all components are fully functional and correctly installed. Overheating can also cause shutdowns; check fan operation and thermal paste.
9. User Tips
- CPU Compatibility: While the motherboard supports AMD Ryzen 7000 series, newer CPU models (e.g., Ryzen 8000 series) might require a BIOS update for full compatibility and optimal performance. Always check the MAXSUN support website for the latest BIOS versions.
- BIOS Updates: If you plan to use a CPU released after the motherboard's manufacturing date, consider updating the BIOS. This can often resolve compatibility issues and improve stability.
- Component Installation: Always ensure components like RAM and graphics cards are fully seated in their slots. A common issue for boot failures is improperly seated hardware.
- Driver Installation: After installing your operating system, install all necessary drivers for the chipset, LAN, WiFi, and audio from the MAXSUN support website or the included driver disk (if applicable) for optimal performance.
