I have chipboard floors across the upstairs of my house - with the
chipboard
screwed into the joists.

These are pretty squeaky and, given we're likely to be soon replacing the
dodgy old thread-bare carpets with decent ones I figure I should fix the
squeaking now before the new carpets go down.

Does anyone know the cause and the fix for this squeaking? Is it simply a
matter of lifting the boards and re-screwing them down firmly, or is
something more involved recommended?

How about dusting talc down the T&G joints?
