Have you tried the serial console? Also, what peripherals are attached? Right now it looks like the hardware is bad, but it might be something connected to it as well. For serial port you’ll need a null-modem cable, though I doubt a non-null-modem cable would harm anything…it just wouldn’t work. It really sounds like it is time for RMA.
