4. South bridge and peripheral issues. Southbridge mainly manages the external device.  Southbridge failure will cause a blue screen. In addition, this will also affect the peripheral fault. In our usual maintenance, we can first enter the safe mode to see if there are blue screen and crash without loading any drivers.
