You could try some short screws to tighten things back up, but only screw directly next to an existing nail to prevent hitting a pipe or electrics.

Quite likely chipboard in big sheets. You might have a joint between two boards that is not supported by a joist but hanging off the T&G. I've got these I hear if they're glued well they hold together but mine weren't You can detect these of you stand on the boards either side of the join and they move separately.

you could try playing loud music
