It could mean your PSU isn't supplying sufficient power too.

The click sound is likely coming from the head mechanism, driven by a magneto type process. It hasn't got power to operate so it's springing back to its base rest ..."click" ....


Try disconecting all other hardware and see if it works then. If so ... PSU upgrade.

As above ... Backup data.

Also, does it only happen at initial startup. Cold starts can be problematic as well. Stiff mechanisms that is.
