Broken macbook today - any ideas?
I took my macbook to work today in thinking that I would actually have to use it. i took care of it, set my bag down gently, made sure nobody stepped on it, etc. I ended up not having to use it, go figure. So I am getting home and I took it out to find quite a nice surprise 
Anytime I press the following keys down, a strange rattling/vibrating sound comes out of the computer. Basically G H J K T Y U I O 5 6 7 8 9 0 and the f-keys. That zone of the keyboard.
The strange thing is is that the harder I press down, the louder the rattling gets - almost as if a needle is spinning against the bottom when I press down. Anytime I press the macbook casing down in this area, the same rattling occurs, ruling out the possibility that it is in the keys. I can't seem to get a video, but all I can describe it as is something spinning against the bottom of the keys, and the harder I press them, the louder and more intense it gets. This has never happened before - any ideas?

My guess is that the fan is dislocated.
Is the computer completely dead?
