  MacPro Non Responsive (LED: CPU A and B FAIL)

  Posted by Ryan Turner on July 14, 2010 at 10:18 pm

  I have a MacPro (intel based) roughly 2+ years old. Two days ago I attempted to start it up and every sounded normal (fans running disk movement) but no tone, no monitor activity and no mouse activity (no light). Since this I have zapped PRAM, removed all other devices, and hit the reset button inside the CPU. And still nothing, just sound of a working computer and the light white light (not blinking, as if everything was normal).

  This morning I was looking at the LED diag. inside and noticed it read CPU A and CPU B had red lights on FAIL. Is there anything else I can try or is my computer a giant paper weight now? One of my friends said it was most likely a fired motherboard (if so can it be replaced?)

  Thanks for any direction or advice!!!!!
