I have done several previous builds. This time I purchased a combo ASRock N68C-GS FX motherboard with the ADM Athlon II X2 270 (Part #ADX270OCGMBOX). On first boot Fans spin, no POST, No Beeps, No Video. The ASRock CPU support list does not show this Part#. The closest is ADX270OCK23GM. So does anyone know if the ADX270OCGMBOX is compatible? And yes, I checked the cabling. I even tried pulling the DDR. At bare minimum I expect POST beeps.
