This strange thing is happening again today - can anyone here tell me why?
Every once in a while - with no pattern as to when - my computer starts up with a sound like a doorbell: a series of 4 musical tones. Sometimes the 4 beats repeat 3 or 4 times, sometimes only once.
I can't see a connection to what's on the screen - I've been doing research this morning so have been all over the place trying to learn more about a variety of cities in Nebraska. Sometimes it happens when I'm on one of those pages, sometimes when I'm looking at email, or reading an Active Rain post.
This happened before, a few weeks ago. When it stopped, I forgot all about it.
Now I'm really curious. What IS this?
Should I be worried?
