[Osbor]

wait, i think i found the issue

i tore it down to the mobo, and found one entire corner of it discolored white and green with residue on it (consistent with copper oxidation), the tray had some on it too. looked almost like battery acid.

the copper trim around the edge of the board is discolored black in that area, is this causing a lack of ground on the board, and thus a kind of short, preventing the system from distributing power?

should i grind off the damaged layer of copper with my trusty ultra-fine sandpaper?
