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've tried all possible resets etc. See my video for more details. Even paying for help at the local ASP didn't help me: http://www.youtube.com/watch?v=uq2LHDMFmHw Thank you for trying to help me out.
