Strange Noise At Startup

A friend give me his powerbook to see what happened: powering it, I ear a strong and strange noise ... I think 3 matters: optical drive is over, fans o HD ?

Another problem that I've see it's typical folder with question mark that means system/drive damaged.

I taped this noise with my iPhone.

Could I upload this record ?
