That's my computer plus a DVD burner. I got the parts in and put it together Monday evening after a couple hours of confusion. It booted, and I installed Windows, drivers, A/V software, Chrome and a game. They all work fine. So I turn it off, and press the power button... the fans spin for like a second and that's it. Power button again, nothing happens at all. So I unplug the cord from the wall socket, plug it back in, hit the power button and it boots just fine. Thinking that it was maybe a one time occurrence, I was proved wrong. Whenever I turn off the computer, in order for it to boot afterwards, I have to either flip the switch on the PSU a few times or unplug it from the wall. Does this makes sense to anyone? I've already seen the thread with the common fixes for fan spins but no boot, but I didn't think those would all apply seeing how removing electricity from the equation causes a quick fix. I do not want to have to flip the PSU switch every time I want to use my 2 day old computer.

Any insight is highly appreciated.

Ok. So that trick doesn't work anymore. What's the chances of irreversible damage had been done even though the computer booted 5-10 times? It couldn't have been a short or anything since it worked temporarily, right?

It's hard to rule out "a short or anything" because it's a new build. Go through this guide very thoroughly and completely to find the problem. http://www.tomshardware.com/forum/261145-31-perform-steps-posting-boot-video-problems

I have the same problem as you, sometime boot normaly, sometime i have to disconect from the wall and reconect to boot, and to make the story short, finally my psu (ocz modxtream 600w) fried and burn my dvd writer, thanks god it was just that.
i will recomend to use another psu to see if your having the same problem as me before is too late. btw the computer turn everything whit that old psu but didnt get a boot, i just buy a new power supply and everything works great.
