Title:

Mac Pro won't boot

Text:

Everytime I press the power button, the white power LED comes on for a few seconds, and I hear fan noise then the machine just "clicks" off, almost as if someone removed the power cord abruptly. Needless to say, I didn't remove the power nor was the supply interrupted. I've tried diagnosing the problem by removing external devices one by one, but that made no difference. Also I did all the resets you can think of etc.

I've made a video so you can see the problem yourself. The ASP was unable to locate the problem.
