Moms windows 2000 pro machine just beeps at her and me when we try and turn the computer on. Where do I start? or what is the problem Thanks apache2

Is this a new problem?

Just one beep?

What is the exact make and model?

Does it beep right away or does the BIOS try to load at all?

Beeps are error codes that depend on the BIOS version for translation.

Often constant beeping at power on is a RAM problem.

Are you familiar with working inside computers?
