    As with many such faults, you need to start somewhere.

    The power supply is often the best place.

    Does it have the correct voltages? Is the current drawn excessive on any rail? Is the power supply shutting down (and is thus the reason for the major symptom (if not the actual cause)

    Beware that power supplies can kill.
