Weird noise when starting...

My MY05 3.oRB wagon has a weird sound under start up, its not the engine itself, but it sounds like the starter motor or something..
Pretty much if you hold the key for too long it makes a screetching sound, and when its cold there is a nasty vibration sort of sound (as if the fan was hitting something)
any ideas??
