How good is the temp. control on your oven? I am not saying this is
imposable just unlikely.
More likely is that you added capacitance when you went from a bread
board to the PCB or that interference that was physically more spread
out got closer when you made the PCB layout.

I notice the CPU is socketed could you please try powering up the
board without it.
