    Because they both come on, going to say that the front pc3 card is pooched. Does the fan come on? Dust will stop that fan from turning, Its a 24VDC fan if you wanted to check it.

        the fan

        The fan spins by hand but does not come on, it also appears to be clean I will remove fan and check it if needed.
        Thanks

          fan removed

          I removed the fan from the circuit, it powers up with no issues. also removed board for visiual inspection, no damage. other than a very light dust here and there

            Well, the PC3 is pooched, very seldom are you ever going to see damage on a board without a Microscope
