5. Troubleshooting
This section addresses common issues you might encounter.
5.1. No Power / No Boot
- Verify all power cables (24-pin ATX, 8-pin CPU) are securely connected to the motherboard and power supply.
- Ensure the power supply switch is in the 'ON' position.
- Check that the front panel power button connector is correctly attached to the motherboard.
- Test with a different power supply if possible.
5.2. No Display Output
- Ensure your monitor is connected to the graphics card (if installed) or the motherboard's HDMI/DisplayPort (if using an APU with integrated graphics).
- Reseat the graphics card and memory modules.
- Try booting with only one RAM stick installed.
5.3. Bluetooth / Wi-Fi Connectivity Issues
- Ensure the external Wi-Fi antenna is securely connected to the rear I/O panel.
- Update your Wi-Fi and Bluetooth drivers to the latest version from the GIGABYTE website.
- If Bluetooth devices disconnect after sleep mode, try disabling USB selective suspend settings in Windows Power Options or updating the BIOS to the latest version, as this has resolved similar issues in some cases.
5.4. BIOS Reset
If you encounter issues after changing BIOS settings, you may need to reset the BIOS to default settings. This motherboard does not feature a dedicated BIOS reset button. To clear CMOS (BIOS settings), power off your system, unplug it, and remove the small circular battery (CMOS battery) from the motherboard for a few minutes. Reinsert the battery and power on the system.
