Sqeaky noise sounds like plates grinding???

[DSM BoosT]

Ok So I have two videos here to show what I hear..... Anyway I did alot of research on threads on here similiar to this but all the things ive tried dont work and nothing that has been said already i believe is working. So I thought if people heard what I heard they might be able to tell easier then trying to explain.

This is what I know already, i tried to see if there was any play or that the HB is coming apart but the rubber is all intacked and doesnt looked like it is trying to split, or is it??? I tighten that as much as I could but when trying to tighten it was already really tight so i dont beleive that its loose, the alt pulley might be loose but i dont know how to tighten it, also the belt that hooks around the alt and crank and the pulley above the crank (what is that one) there is alot of slack (HOW DO I TIGHTEN that belt). So please help me out i sprayed some stuff on it to see if the squeakin went away but still there, Im more concerned about the metal grinding sound. Also how do I tighten the bolts to the pulley above the HB do i need to remove the motor mount because I cant reach it no room to turn the bolts. thank you bear with me i know I have alot to learn but really enjoy working on these cars and learning more about them everyday so please help me!

Tighten up the alt belt. The adjustment is on the alternator. You loosen the bottom bolt of the alt then the bolt on the front and turn the adjustment screw on the top. The other pulley is the water pump.
