My MacBook froze while watching this retarded Youtube video: http://www.youtube.com/watch?search=&mode=related&v=VqwcesixkQg It's a couple of kids fighting in a parking lot. hehe! amusing. Anyways... that was a first. Never happened on my iMac before. Never even knew it happened. All I ever had before was Finder hangups (beachballs) and a kernal panic or two. The MacBook's only about three weeks old. What causes random Windows-style freezes, where everything just completley locks up and you hear the audio repeating over and over? Should I be worried? Is this common? thanks.
