not sure what to do

took the mobo out and the case intrusion jumper was off

replaced that and still no boot

took mobo out

GPU powered, Ram installed 24pin powered , 4 pin powered = no boot

replaced 8400 with e6700 no boot

has to be something simple Iam missing or its bad out of the box

Iam going to try my P5W mobo with the 8400 and see if that will boot
