CPU temperature, system temperature

CPU fan speed

Each voltage value (Vcore,+3.3V,+5V,+12V, etc.)

5.7 Exit (Exit menu)

Load Fail Safe Defaults: The default value for loading stability first

Load Optimized Defaults: Default values that prioritize loading performance

Save&Exit Setup: Save and exit

Exit Without Saving: Discard modifications and exit

Chapter 6: Quick Troubleshooting Table for Common Malfunctions

Troubleshooting steps for possible causes of fault phenomena

There is no response when powered on, and the fan is not running. ATX 12V (JPW1) is not connected. Check if JPW1 is securely plugged in; Check the power output

There is power but no display. The CPU/memory is not installed properly, and the Init Display First setting is incorrect. Reinstall the CPU and memory; Check Init Display First (Onboard/PCI)

The system repeatedly restarts or crashes, and the CPU has poor heat dissipation and high temperature. Check the contact of the heat sink and the thermal grease; Check the temperature reading of PC Health

COM1 communication failure JP1/JP2/JP3 jumper mode mismatch. Reconfigure three sets of jumpers based on device type (RS-232/422/485)

SATA hard drive does not recognize SATA cable with excessive bending or loose connection. Check SATA cable (cannot be bent 90 °); Check if SATA Port is enabled in BIOS

IDE device cannot recognize master/slave jumper setting error check IDE device master/slave jumper; Check IDE1 connection

The network card cannot connect to the LAN controller and is disabled, or the PXE ROM conflict check shows that Onboard LAN 1/2 is enabled; Check Boot ROM settings

USB device is invalid. USB Controller disabled or Legacy Mode not enabled. Use USB Controller and USB 2.0 Controller

BIOS settings cannot be saved (time lost). CMOS battery is depleted and replaced with CR2032 button battery; Reset date/time

BIOS update failed or unable to write BIOS Protect enabled. Disable BIOS Protect in Security before attempting to update

The system is unable to boot LAN Boot ROM from the network. LAN Boot ROM is not enabled or has been configured incorrectly to enable Onboard LAN Boot ROM; Check Boot sequence

Parallel Port Mode does not match the device and the parallel port printer is unresponsive. Attempt SPP/EPP/ECP mode; Check address settings

Chapter 7: Preventive Maintenance and Long term Stability Suggestions

Cooling maintenance: Regularly clean the CPU heat sink and fan (recommended every 6 months), ensure good ventilation of the chassis, and keep the ambient temperature below 50 ° C.

Battery replacement: The lifespan of RTC battery (CR2032) is about 3-5 years. If the system time is frequently lost, it needs to be replaced in a timely manner.

BIOS Update: Before updating, be sure to disable BIOS Protect in Security, and immediately re enable it after the update is complete.

SATA cable specification: Avoid 90 ° bending and use SATA II cables that meet the specifications (data rate 300MB/s).

ESD protection: All operations must be carried out with a grounded wristband on an anti-static workbench.
