When your computer beeps, it means that an error has occurred in the hardware . BIOS recognizes internal errors and sends signals in the form of beep sounds, indicating the location of the problem in the hardware. When you start your computer and hear strange beeps in the boot up process, it means trouble. It would be good to understand what the beeps mean. When your computer starts-up to perform a power-on self test or 'POST', then the booting problems are diagnosed with error codes displayed on the monitor. The computer architecture uses beeps to indicate an error in a number of patterns and timings of beeps when nothing is displayed on the monitor. Every BIOS has a unique code of beep. BIOS manufactures AMI and Award (now Phoenix) signal different codes for similar errors.
It is not uncommon to get some beep sounds while starting your computer, and they correspond to different errors that can occur with your hardware. Below you will find a list of the most common errors and what they refer to.
