Ok I tried on stick of my new G Skill memory , same result no boot. Took MB out of case , put it on cardboard, with just GPU , jumped power switch, post fine.
So what did I miss when I put it in the case?? A short? What?? Could connecting the case, front panel connectors( HDD LED, etc) have kept it from posting? How do I tell when I hook up the front panel connectors like the PWR SW or HDD LED, which side it the POS and which is the NEG? One wires red , ones white.
OK feeling kinda stupid right now, I think my mistake was mixing keyboard mouse plugs in wrong DIN connectors. I didn't think that was possible, but I thinks that was the problem.
MB posting fine, finishing assembly, next up BIOS, then install windows 7 .
