Well I took a deep breath and plugged in the 12v 4pin connector and fired it up.  I didn't see smoke this time but the thing still wont boot.  Not even into BIOS.  The fans come on but I get no beep and of course, no video etc.  When I initially turn on power to the board the keyboard flashes but that's it.  This is essentially the same problem I've have with this thing from the get go.  By the way, I performed this out of the chassis just to be sure there were no shorts.  I tried clearing cmos again and that didn't help either.

Any more suggestions?  I'm open to all!

Thanks
