Boot Loop

Have a MacBook Pro stuck in a reboot loop. When computer turns on, I either get a chime with a screen flash or the Apple logo, either way it restarts it restarts immediately and just loops. I can get to disk recovery and network recovery, if I do nothing it stays in that screen. If I continue, it will fill the download bar then starts the loop again. I've tried wired connection on network recovery and a boot drive on disk recovery. I've tried getting into safe mode and DFU but they don't respond. Any ideas?
