I bought a KT3 ultra2 and I have not been able to get it to power up ....I mean at all...so how do I decide it is DOA?? not not only that how do I decide if it was sent to me that way or if I screwed up??? ( the underside of one the corners of the board may may been touching the case)( Standoff not secure) but I am not sure...what do ya think??? It was the retail version but I bet I purchased it 2 months ago so...
