[iJawn108]

and i quote:

within the last week my macbook pro has been freezing for unknown reasons
it will start to make clicking sounds (which scare the poo out of me) then everything will freeze...i ..don't ...understand
the sound seems to come from inside the computer
I can't find a solution through google :/
any help at all would be lovely

Hard drive problems. Just get if fixed under warranty.
