If it's pulling down the power supply (I assume 5v for the micro) then you need to start diconnecting things one at a time until you find the component that's loading it down. You might as well start by lifting the Vcc pins to the micro since the show's over if it's bad.

How low do the voltages go? It's also possible that the power supply has failed and can't supply the micro with enough power, but it's fine with no load.
