Mute the speakers and see if this is the usual IE navigation click.
Am having an annoying tapping sound whenever I navigate from one site to another. Sounds like a slight tap of a tin cup. Ran system diagnostics and all is fine. Does not occur when opening docs on word, excel. etc. Before going to Dell Software Support, thought I would run this by the forum. Only had the system for 4 months and agree with other owners; the fan runs more often then not. Thanks
