Solved!
And this is some crazy ass shit too: I was friction fitting the core with the mainboard to see if removing the TVS fixed it (it didnt) so the plan was to try the temporary headers like andy suggested with the minimal setup but my trimmed down, solder coated ones were not fitting the sockets i had so I decided just to put new headers on the core, not a big deal, suck out the solder and pull the pins out one at a time. When I did the first row and pulled off the plastic header there was a fair amount of solder where the plastic was (like it puddled there). I just ignored it thinking it was from the desolder gun and cleaned it all up but after the clean up, and new headers, it fired right up. In hindsight, there was way more solder there than should have been, I was sucking out solder through one end and pulling the pin out through the other, what was left there after I removed the plastic was in the shape of the plastic header like a mold, there is no way that came from the desolder gun especially since it sucks solder out or from any other soldering I did since those were on the other side of the header. I checked all the IO pins for shorts to ground and +5 but NOT to each other which seems to be what was happening here, must have happened in the wave machine when those headers were soldered on at the factory. Just dumb luck i decided to replace those, I would have never found it otherwise, should have taken a picture
