Just got home from Vietnam. It has been 5 weeks.
Walked in, tried to boot up my Mac Pro. It turns on for a second, I get the light above the power button, the fan starts to spin, I see the red lights on the memory daughter cards… Then it shuts off. I’ve tried swapping in different hard drives, what might the issue be here? I thought I’d ask y’all in case it’s something incredibly stupid-easy so I don’t need to tear everything out of the case and try component by component.
