The problem isn't continuous, and when it happens it shuts before POSTing, I'm not facing any boot-loop I don't know if you meant to "force" a boot-loop.. I hope mine magically disappears too ;-)
yeah, POST wouldnt "show" when it used to happen to me - lights on, fans spin a little, lights off - and the process repeats
try what Beej suggested - this board is VERY picky mobo, the slightest wrong contact somehwere will lead to this - i mean its more a less a safety feature -i think i indirectly fixed it with a little cable management - im pretty sure i had some contact issue somewhere.
Also if this helps , when i used to have this problem it would boot fine at first, but after a shutdown and then me trying to turn it on it would have that loop before POST that your having - as i said i fixed this at first by turning off the PSU and then back on.
