I fell asleep and when I woke up I had a second board go dead on me. It doesn't power up anymore. Not sure what to do.

I guess the only thing that you can do now is to completely disconnect that board, let it cool down (edit: letting the polyswitches reset themselves, if they exist, sounds like a good idea), then try it again (ideally in an isolated environment with its own supply, pc etc.). Do you have reasonable cooling?
Good luck
