Vista - Clicking noise from speakers

Every two or three or four seconds I get a clicking sound from my speakers, sort of like would come from a relay. Random spacing, but all of the time. This has not always been the case. I probably turned something 'on' by mistake. Any clues where I might look and turn it 'off'? Vista SP2

One way to narrow it down is to see if it does that in safe mode. reboot in safe mode (F8) and check

In checking around I opened my sound Icon and went to the Volume Mixer. Muting Windows Sounds eliminates it, as does reducing the Windows volume control, of course. Would that indicate that the sounds are from Windows? All other sound levels are as before.

What is around your speakers. You might be getting interference or your speakers are nearly dead.

The speakers are alive and well and play audio perfectly. Location of them hasn't changed nor is anything new around them. Puzzled. Thanks to all for your interest!

Do you have a microphone or something that could possibly pick something up. I think ive had a similar problem but I forgot how I fixed it...

I do have a mic that I use only with Skype and it is off. Scratching on it makes no noise. This other noise sounds like a very small relay. I had a similar on my laptop and found a way to turn it off, as it was a sound generated by Windows. Turning of Windows Sounds eliminates it. I have not been able to find where such can be turned on or off.

Is there an option in the Sound control panel?

Control Panel/Sounds offers: a. Default b. Default Modified c. No sound. To change from those there is a drop down with lots of choices i.e. startup, error, etc. I just select No sounds, and now there are none, and no clicking sound either. Speakers are on and the only sounds I can get now are music or audio, but nothing from Windows related actions.

From this I would have to guess that the clicking is Windows related. Beats me? Thanks for the input.

My setting was Default Modified when I checked it earlier. I found what No Sound meant, so now changed it to just plain Default to see what happens.

Yes, for each of the options, startup etc you can choose what you want. Look for a mic related option.
