Could be any number of things. First place to start looking is just all over the board for anything that doesn't look right. After that, I'd inject 3.3v into the 3.3v rail of the bottom board alone and see what gets hot first. Might just be a shorted Capacitor causing it, might be a fragged MCU or could be anything in between.
