Return to Introduction

When a computer starts up, the very first thing that happens is that a small program in the on-board BIOS gets control and starts executing.

This start-up program is called the “bootstrap”; it is called this because of the image of a man bending down and holding onto the straps of his own boots, pulling them on, and standing up.

Because this is the first thing the computer does, the bootstrap program is also called the "Power On Self Test" (POST).

The first thing the bootstrap does is calculate a checksum of its own BIOS chip; if the checksum matches what was programmed into the chip, it continues with other tests. If it does not match, the bootstrap program knows there is a problem; it could be a defective addressing chip, a bad bit in the BIOS chip, a faulty or overheating CPU, whatever, but it now has to communicate with the outside world (you) that something is not kosher.

It can’t use the monitor, as the graphics hardware has not been initialised yet. It has no physical means of attracting your attention, other that the built-in speaker. So it generates one or more beeps.

Since there are various kinds of errors that can be detected; it generates different beeps. For example, a BIOS error might be a single long continuous beep. Bad RAM might be a series of short beeps. A missing graphics board or unaddressable graphics memory might be a long beep followed by two short beeps.

The actual beep codes vary by manufacturer; there is no universal standard. What you need to do is open the case, inspect the motherboard and determine the manufacturer. Then do a Google search on the manufacturer name and “beep codes” (in quotations).

You can’t do this on the defective machine, of course; you have to use another machine.

You can also use these tables, which show the standard beep codes by BIOS manufacturer. Be warned that these codes could vary with the motherboard manufacturer. But they will give you a starting point.
