Beep Codes

By: Jesse Miller

The procedure for troubleshooting the mother board and the graphics card is essentially the same. Listen to the PC and see if it is telling anything in the form of any unusual noises. If it is, irregular patterns of beeps-known as beep codes. These are produced by the BIOS chip. These beeps are known to convey the message of the computer hardware to others.

If you are getting beep codes then you will need to know what the various codes mean. The different BIOS chip manufactures all use different codes so first you will need to find out who the maker of chip is.

Reboot (restart) the PC and after a few seconds BIOS details appear at the top of the screen. Windows ME users can also get their BIOS details by going to Start, Programs, Accessories, and System tools. By clicking system information and looking under system summary, information regarding the system appears.

The BIOS chip has an inbuilt diagnostic system whereby it alerts the user any problems it encounters during boot up. It does this in two ways a series of coded beeps if the problem occurs before the graphics system has initialized or a text error message if the fault comes after.

The motherboard is literally the heart of the computer system and as such is a complicated piece of circuitry. Every single part of your system is hooked up to this board. There are several different codes relating to the mother board, indicating specific problems with it such as the memory or CPU for example. These types of fault can often be repaired by replacing or reseating the associated chips and aren't necessarily too big a disaster.

However, there is also the possibility of not getting any beep codes at all and this almost means an outright failure of the motherboard. You will usually find that the keyboard lights are not working either. In these unhappy circumstances, then the motherboard should be replaced. Look on it as an opportunity to upgrade the PC; it might make you feel a bit better.
