Beep Codes
Your computer may emit a series of beeps during start-up if the monitor cannot display errors or problems. This series of
beeps, called a beep code, identifies a problem. For example, beep code 1-3-1 (one possible beep code) consists of one beep,
a burst of three beeps, and then one beep. This beep code tells you that the computer encountered a memory problem.
