5. Troubleshooting
This section addresses common issues you might encounter with your ASUS Z170-DELUXE motherboard.
- No POST (Power-On Self-Test) / Error Code 55:
- Error code 55 typically indicates a memory issue.
- Ensure RAM modules are fully seated in their slots.
- Try booting with only one RAM stick, testing each slot and module individually to identify a faulty stick or slot.
- Verify RAM compatibility with the motherboard's QVL (Qualified Vendor List) on the ASUS website.
- Update the BIOS to the latest version, as this often includes memory compatibility improvements.
- No Video Output:
- Ensure your monitor is connected to the correct video output (integrated graphics or dedicated graphics card).
- If using integrated graphics with a 4K display at 60Hz via HDMI, you might experience a blank screen. The integrated HDMI port on the Z170 chipset may be limited to 30Hz at 4K resolution. Consider using a DisplayPort connection or a dedicated graphics card for 4K 60Hz output.
- Reseat your graphics card if applicable.
- Check monitor input selection.
- System Instability / Crashes:
- Ensure all power connectors are securely attached.
- Check CPU and GPU temperatures. Overheating can cause instability.
- Verify RAM stability using memory diagnostic tools.
- If using RAID, ensure Intel Rapid Storage Technology (IRST) drivers are compatible. Some IRST driver versions (e.g., 14.8.1.1042 or 15.2.0.1020) have been reported to cause issues with certain configurations. Try using an older stable version (e.g., 14.0.0.1143 or 14.5.0.1081) or uninstall IRST if not using RAID.
- Ensure your power supply is sufficient for your components.
- Peripheral Not Detected:
- Check physical connections.
- Install or update relevant drivers.
- Test the peripheral on another port or system.
