help! ceiling "coming down"

Hello, I couldn't find a clear place to post my question, so I hope I posted in the right place(?) (The house was built in '99 by JM) In our living room, the ceiling is sagging in a few places. Above the living room ceiling is the upper floor's floor. The ceiling is a regular gypsum ceiling. It needs to be fixed because I want to be sure that the projector and other expensive items won't fall down... (it was sagging before the projector was installed) A bit worried about how this could happen, so I made a hole with the hole saw, and as I suspected, the beams have come loose in a few places (they are nailed to the cross beams, which in this case are the floor beams for the upper floor). It looks like it has only come loose in one place, and the weight has caused it to come loose along the same row along the beam, so to speak, meaning it's just one beam length that has come loose in a few places (maybe three beams). Lucky that there's no moisture at least... Now to my question. I've figured out a few options but still want to hear what you think I should do to fix it as quickly and smoothly as possible (with minimal intervention). I want to screw because I think it should be the most durable; am I wrong? Tearing up the floor on the upper floor is not on the table, and perhaps neither is tearing down the ceiling in the living room. To lift the ceiling back up to be able to screw it, I was thinking of bringing in a jack and a wide and long beam to spread the pressure over as large an area as possible. Option 1. My first idea was to remove a bit of the gypsum at the points where the beam is attached to the joist with the hole saw and maybe screw it instead of nailing. Then glue/screw the gypsum piece back again. Option 2. Screw through the gypsum and thus not make holes to access the beam. This feels like a slightly worse option since the gypsum gets a lot of pressure on a small point, and also, you would see the ugly screw heads. How would you do it? -Johan

Nice that it was resolved so smoothly!!!

cc60 and cc120 are common, but if the bjälklag has a floor on the top side, I think cc60 is what applies in most cases...or?
