OK. Breathe.... Now, you have to verify each component, one by one somehow, in another board, to be sure it is good. Once that is done, then put NO connecters on the motherboard (IDE LED, power led, etc..), except the power-on connecter (required, even if you manually jump it) to make sure no problems there. Also, NO HD, NO floppy, NOTHING except video, memory and CPU. THEN report back the results.
