I fear you may be right Sir. I just tried a brand new CPU, perfectly installed, held my breath and pressed the power button, and it has exactly the same problem. Red light comes on the mobo power button, but no boot at all. I just don't know what I coould have damaged except perhaps the socket somehow. It's never happened before.The spontaneous power on definitely shouldn't happen. Hate to make things worse but I'd seriously look at the mobo as the culprit.
