I found the reference I was looking for to solve the annoying clicking in Windows XP/2000. It was from Micro2000 Tech Tips. Here it is:
Stop The Clicking
A couple of versions ago, Microsoft added a clicking noise to Internet Explorer so that each time you click on a link, you hear an audible click, which many of us have found annoying after a while. In the Windows XP control panel, open Sounds > Speech and Audio Devices > Sounds and Audio Devices > Sounds tab. For Windows 2000 it's just Sounds & Multimedia. Scroll down to the Windows Explorer section. Click the event called Start Navigation, and change the setting to none from the dropdown box. Click OK to apply the change. You are now free from the annoying clicking.
