an audio beep or in the form of a code number flashed across the screen. With this audio code in hand, you can determine what part of http://www.pchell.com/hardware/beepcodes.shtml the system is having problems and find a solution. The pattern of beeps whether its the number of beeps or the length of those beeps will give you an indication of the actual problem. http://www.5starsupport.com/info/beep_codes.htm Its a distress signal from the computer in a morse code like pattern. Unless you have a diagnostic card to tell you more about the particular problem, you will have to use the beep codes charts below to decipher the computer error and get your machine back up and running.

is a short diagnostic procedure incorporated into the boot sequence by the BIOS manufacture for troubleshooting purposes. Many times when there is an error in your boot sequence you will receive an on-screen error message. This error was printed by the video card. But, in some cases, the error is detected early in the boot process and the error cannot be received by the video card. The problem may even be caused by the video card or the monitor. This is why the need for beep codes came to be. Below, you will find some common codes listed by manufacturer. Use the information below at your own risk.
