If the balloon is what I think it is, a file in windows has a typo that sets the notification window that pops up from the system tray to some location off screen and its throwing an error because the location doesn't exist on screen. My guess is windows is trying to alert you and it can't so it shows that instead. More than likely its just a downloadable update alert anyway so ignoring it wouldn't be a huge deal. But I'm one of the lesser techie types around here so take my opinion with a grain of salt. Someone more knowledgeable will come along sooner or later. But FYI we have a help forum for these things
