This post is part of the series Boot-up Troubleshooter.

If somethings wrong with your motherboard and/or graphics card, then your PC will make some unusual noises in the form of beeps, these beeps are known as beep codes. These beep codes are actually produced by the BIOS chip.

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

Depending on your BIOS manufacturer, the beep codes will vary, so you’ll need to know who your manufacturer is before you analyze whats wrong with your motherboard and/pr grpahics card.

Finding who your manufacturer is very easy. As soon as you re-boot your system, you’ll notice your BIOS manufacturers detains at the top of the screen. You should quickly make a not of it as it won’t be displayed for long.

If you are a Windows ME user, you can get your BIOS details by:

::> Start -> Programs -> Accessories -> System Tools

::> Click System Information and look under System Summary.

There you’ll find information about your BIOS Version.
