If There is a Beep Code During Boot
If an error occurs during the Power-On Self-Test (POST), which
prevents the PC from starting, the system issues a beep code before
attempting to display the error in the upper left corner of the screen.
Beep codes are useful for identifying the error when the system is
unable to display the error message.
