Since I went on broadband, why do I sometimes suddenly hear bird
chirps ... from different sites.  It's almost like someone does it as
a joke, to let me know they are in my system?! Thanks for answer.

Do you have the Google toolbar installed?  The popup blocking feature
makes a little sound, which surprised me the other day; usually I have
my speakers turned way down.

Thanks A for trying to solve my mystery but I don't hve a google
toolbar, and chirps dont happen when I google. V

Are you sure it's from the website?  I have HDD Health installed on my
system and it chirps sometime.

Do you use AOL?

I am on AOL, seebeem...do sometime chirps come from that connection?

Do you have WeatherBug installed? www.weatherbug.com   That's the
program that shows the current temperature down by the time on your
task bar.  Whenever a weather alert is issued, it will "chirp" to let
you know you should check it.

Thanks to sickpc...but I don't have weatherbug, so chirps don't come from them.
Yikes they just started up right now...maybe they're from google!
