Re: still nothing!
I take it you're not even reaching post or able to access the bios? correct?
I'd strip everything back to basics, 1 stick of ram, hdd, video card and see if it will post.
Check that the m/board is not earthing out on the case anywhere and that the risers are properly positioned, if all is good in that department I'd be looking at RMA for the m/board. Sounds like the board is DOA to me.
ECS is not a well recognised brand, try a different board manufacturer if you can.
Asus if you can afford it.
