6. Troubleshooting
This section addresses common issues you might encounter.
- No Power/No Boot:
- Ensure all power cables (24-pin ATX, 8-pin CPU) are securely connected.
- Verify the power supply is functioning correctly.
- Check front panel connections, especially the power button.
- Memory Issues (e.g., Code 55):
- Ensure DDR4 memory modules are fully seated in their slots.
- Try using only one memory stick at a time to identify a faulty module or slot.
- Verify memory compatibility with the motherboard's Qualified Vendor List (QVL) on the GIGABYTE website.
- Some memory modules may require manual adjustment of voltage (e.g., from 1.2V to 1.25V) or a slight reduction in clock speed (e.g., from 2400MHz to 2133MHz) in the BIOS for stability.
- No Display:
- Ensure your monitor is connected to the correct display output (either integrated graphics or a dedicated graphics card).
- Reseat the graphics card and ensure its power connectors are attached.
- Test with a different display cable or monitor if possible.
- Operating System Not Loading:
- Check the boot order in the BIOS/UEFI settings.
- Verify that your storage drive containing the OS is properly connected and detected.
- SATA/M.2 Port Disabling:
- When using M.2 drives, certain SATA ports may become disabled due to shared bandwidth. Refer to the detailed motherboard manual for specific configurations and port limitations. Plan your storage setup accordingly.
