If you've not done so, go back to the very basics of system POST debugging, starting with visual inspections, the bare minimum of components, etc

Follow ALL power disconnection and ESD handling protocols when handling or configuring devices and the motherboard. For example, just "turning-off" a system by pushing the front-panel on/off button does NOT remove all power from the motherboard and some peripheral devices. And disconnecting devices/mobo when ALL the power is not removed can cause catastrophic damage and make what would have been a simple problem much worse. Similarly, improper ESD handling protocols can cause undetectable catastrophic damage. How you handle parts is at least as important as making sure you are using known "good" (individually tested) parts.
