I'm having a strange and bizarre issue with my mid '07 MacBook. For some reason, when I press the 'U' key on the keyboard, it makes a buzzing noise. It's not very loud but it's loud enough to get annoying when I'm using my MacBook in a quiet surroundings. This problem literally just started as I was using it today. When I press surrounding keys it doesn't make the noise, only when I'm pressing the U key. More interestingly, when the fans get louder, so does the buzz. There seems to be a correlation between the loudness of the fan and the loudness of the buzz. I've uploaded a video to further illustrate my problem:

Does anyone know why this is? Also, do you think my MacBook is slowly on it's way out? Besides this issue, It's started giving me slight shocks when I touch a metal part (e.g. a screw) when it's plugged in via mag safe charger.
