After waiting a while to get a tri-wing screw, i was finally able to open up my Wii to fix the "loudness" problem". Lightly lifting the bit you get told too in the tutorials, the vibration did get quieter. I accidently touched the eject mechanism though and now the round-disk thing is setting far too low, too low to even accept disks. I tried spinning that wheel of the mechanism but all of the cogs were spinning. I've been fiddling about for a bit to no avail and i think now it's the time i just stop and ask the experts before i do any real damage.

Thanks in advance for any advice.
