Why is my Computer Beeping?

Whenever you power on your computer, the system will first look for the Basic Input Output System – Read Only Memory (BIOS-ROM) chip on your motherboard. Inside this BIOS Chip is a small program of instruction telling the computer where and how to access the different slots, ports, drives attached to your motherboard. The programming code and instructions on the BIOS will be loaded in to memory and carries out the instruction in order. The computer then takes internal and external inventory of all equipment attached to the computer and performs several self-test or Power on Self-Test (POST). During the POST process if ever an error is detected the error may be delivered through visual that is shown on your Monitor and or audible known as beep codes through the motherboard speaker.

The pattern and number of beep codes has differing meaning telling you what is wrong on your computer hardware, error codes may differ from manufacturer to manufacturer so consult your motherboard manufacturer manual for more detail.
