I assume you checked every single cable and all that. The next logical step would be power or motherboard. If all cables are good and there is power often it's motherboard at fault. This does sound like a motherboard issue i am afraid. Still could be something different. You need extra hardware to troubleshoot like another board to test the parts on.
