The beeps are actually a fault code issued by your BIOS to alert you to the general area of the problem.
Who makes your BIOS? Is it Phoenix BIOS, AmiBIOS, etc.?
How many beeps is it and in what pattern are they? For example, in Phoenix BIOS, 3 beeps followed by 1 beep and the 1 more beep indicates a possible problem with your secondary drive.
Here's a link to a webpage that has tables for the beep codes used by the various manufacturers....
