Why is my Computer Beeping?

When you turn on a computer, the computer’s first job is to perform a P.O.S.T. or power on self test. The computer checks itself to see if the vital hardware and systems needed to run the computer are functioning properly. If something fails in the middle of the night and your computer cannot properly complete a post after you turn it on, it will signal you something is wrong by beeping. The number of beeps you here will determine what kind of problem you have. You can find more information here:
