The clicking noise and the folder/? icon is the "best" sign for a defective hdd.
there are not many options to handle that.
i use a external harddrive connector set and try to save as much data as possible from those failing drives - yes - in that case i first try to save the date and after that i try to boot the computer.
boot the from the setup disk and start the disk utility and try to check/repair the volume/permissions
if you don't have the possibility of getting a external usb hdd connector set - or simply have no important data on the drive - you can skip the backup part
