820-3476-a That Freezes

I have a 2013 820-3476-a that is in great condition with no sings of liquid that turns on but freezes within 10 seconds to 1 minute. I have tried minimum system configuration, different flash drives, different os's. It also freezes on an os install/setup screen and even before loading into the os (apple logo with mouse) . Basically to it seems to me I have narrowed it down to the logic board, Is there anything I can do?

it just freezes, no video distortion, does not restart, external mouse does not work either.
