It's difficult to diagnose this without more information.  Like your whole set-up.

For some reason, it sounds like your board is not responding.  Have you tried another USB cable?
Facts just don't care if you ignore them.

I have had that message after unplugging and re-plugging the Arduino while the IDE serial monitor is open. Try un-plugging &restarting the IDE. Seems the OS assigns a new COM port for the board and the IDE sticks with the old one ( can't reselect in menu either ).

I'm running windows 7 so this may be irrelevant to you.

Are you using the Arduino Software 1.0?
Try it with an older one.
There is a bug see
