I am so lucky that I have so many donor boards, but that is because I only work on two Dell motherboard models. If I needed parts for random faulty motherboards, I would be in trouble.

(15:22 exactly) DDR DIMM connector (empty, where you don't have the RAM module) the corrosion is seen very close to the black plastic although the terminals seem to be well soldered to the PCB. If the other DIMM Connector is in the same condition, that would explain the zero (0) volts you indicate on the body of the inductor. Furthermore, a damaged DIMM connector and/or RAM module causes no image on the screen. Just to the right and also above the CPU (which has the exact shape of a square) there are two QUAD type ICs, I would extract them to properly clean the pads and then return them back to the board, that is, an attempt to see if the 0 (zero) volts indicated on nearby inductors change. (16:23) Totally agree. Put me in your place: “the fluctuation is killing me” (it has already exhausted my little patience)... damn. Okay, I can't take it anymore, I'll order new ones to change them. Thank you very much for the measurements shared (reference when you face another similar board). Don't put pressure on yourself when the content you show us doesn't have a solution when you present it because we always learn something. All the best.

I'm not sure if the RAM memory voltage is meant to be on before pressing the power button - I will check the datasheet and see if it gives any indication. I took the photos before cleaning with alcohol, however when I looked closer there is some sort of gunge on almost all of the pins of both DIMM sockets even after cleaning - like the sticky remnants of a sticker that has been half pulled off. I have no idea what this could be. I will get out the toothbrush and see if I can remove it somehow. Thank you for your comment.
