My name is Debbie.
You will have to know what software or processes are running on the background in order to find out what is causing the popping noise if it comes from the speakers. Many of the websites are nowadays using background processes (called AJAX technology) while we are browsing, that may cause an occasional clicking sound. It should not be harmful if it is the site's background activities are causing it.
But there are some things you can do to try and isolate its cause.
First of all, I would want to rule out the most obvious: sounds coming through the speaker. Turn the volume control all the way off or disable the audio system by going to the Sounds control that is part of the Control Panel. If the noise stops, then you would seem to have either a failing sound system, a problem with the connection to the speaker which is causing a click or a program that is generating a click. But none of these sounds will come through if the sound system is turned off.
Now, assuming the sound continues: I would think there are a few other possibilities.
1) The fan could be clicking/popping. This is one of the few moving parts of the computer (along with the hard disk drive and the CD or DVD drive). A failing fan could make noise. Put your ear to the output of the fan and try and determine if the sound comes from there.
2) And now the hard disks drive. In most laptops, the location of the hard disk drive is obvious. Find the hard disk drive and put your ear to it to try and determine if it is the source.
Now: if you think the sound is in fact coming from the hard disk drive, kindly run the Dell Diagnostics.

3) The last step I can recommend to you is that kindly go ahead and update the Audio driver of your computer by going to this URL:

4) If still nothing works out I would recommend you to back up your data and then restore your system back to the factory settings. In order to restore the system back to the factory settings, kindly go through the URL which would explain you the step by step process with the snapshots:
