Seems pretty dead. I am not sure what else to try. I would like to repair
this machine, but I first must determine the problem.
I thought perhaps the motherboard might be dead, but I noted that when I

RAM, there is no noise, just fans running. (All LEDs turn on successfully)
This leads me to hypothesize that perhaps it is the CPU that is bad?
