I checked both cpu and gpu vcore just to make sure they were present and both are. Figured its a dead gpu so I did a reflow with some chipquik and yep it came back to life for a few minuets and then when i restarted it the board booted up to a bunch of multi colored flickering squares. Into the parts bin it goes.
