BBBOOOONNNNGG!!!!

My notebook just died on me....I was working on photoshop 7 when I heard a rather loud tone from it then about 2 hours later the loading beachball kept spinning forever and the finder is not responding so restarted the computer only to find a picture of a folder with a question mark on it.....GAH!! oh ell I gues I'll just turn it off and check again in an hour or so, I'm going to do a systems check once I get back home
