I recommend you get a good, clean backup of that thing right now, and
keep it backed up to within a couple days or the amount of work you can
afford to lose. Sounds to me like something is on its way out.

The fact that you upgraded just prior to this symptom's appearance
casts an accusing finger at the upgrade, and that certainly should be
investigated. But just in case it's a coincidence, you should do what
everyone else said about hardware diagnostics. And I'd like to add one
further diagnostic...

Remove the cover from the machine and start wiggling wires, hard. Does
it seem like you can trigger the click by moving the wires? If so, move
ever fewer wires til you get one wire or one cable that seems to
trigger it.

I had an intermittent click several years ago that turned out to be a
defective hard disk power connector.
