New build turns on then after about 10 seconds turns off, then after two seconds turns itself back on, repeat.

I have been searching online for an answer. I went through the forum's won't post, turns off and on sticky, problem persists. I've also been on reddit for weeks trying to figure out a solid answer to this question.

So I decided to build my first PC, easy enough right?

I've had this issue for the last two weeks. My computer turns on for about 10 seconds, doesn't POST, and turns itself back off. Then boots itself back up again after two seconds and repeat. I've tried damn near everything.

Here are my two most recent reddit threads:
https://www.reddit.com/r/buildapc/comments/41585f/troubleshooting_build_turns_off_and_on_endlessly/

https://www.reddit.com/r/techsupport/comments/414pto/new_build_turns_off_and_on/

I'm seriously stumped as to what the problem may be! Any advice would be welcomed.

I have an EVGA 600W in there now. Old PSU is now a cat toy. Problem is still persisting, I've changed out my Motherboard and I'm on my way to pick up a new cpu to try out. crossing my fingers this works.

Update: didn't work

Have you by chance tried to POST your build outside of your case? Reading your posts on reddit, it looks like you have replaced everything. Maybe, just maybe it's your power button on your case. I have seen this happen before, just not with 10 second intervals.
