Not debating your diagnosis, speedster, nor down-playing your good advice, merely offering an alternative as well as adding an addendum to help firm up your diagnosis (run diags). There are 4 key points to the issue: “laptop” {(it’s nearly impossible to tell what component is making the noise and where the sound originates) (onboard speakers tend to sound “tinny” and lend a mechanical tone to .wav files)}; “random beep” (hard drives don’t beep); “a click” (of death generally isn’t a single click nor is it random); “beeps and makes a loud click” (the two sounds occur together).
Generally, BIOS doesn’t do single beeps after posting; any alarms or notifications from BIOS would be a series of beeps indicating this is a “software” beep. Many programs (XP, ms office, outlook, instant messenger, etc) use sound schemes that “play” .wav files. There are several dozen .wav files that are simple beeps and clicks that may occur for any number of reasons, ie: improper capitalization, a word being placed on the clipboard, autocorrect making a correction, etc. Yet another source is “accessibility options”. While this is a more elaborate example of sound schemes, try this: Turn up the volume, click start>all programs>accessories>accessibility options>narrator.
I could be wrong
