Fans Spin, No Beep, No Boot

Hey all,

So I've been working on this computer for a few days now and am about ready to pull my hair out. This is my first build so at first I thought I must be doing something wrong but now I'm not so sure. When I first did a test boot I did not have a mobo speaker, nor did I bother to plug in a monitor like a true noobie. My fans spun up then stopped when I shorted the pins and I assumed the fact that they moved meant that everything was working. When I finished getting it all together in the case, and finally plugged in my monitor, I realized it was not booting.

So I started troubleshooting. First issue I noticed was that my PSU was acting odd. I was using a 750W Fatal1ty PSU. For whatever reason every few times I turn it on the led's would flash on then off and the PSU would not start up. After that nothing would happen (not even LEDs) till I unhooked the larger (32 pin?) connector and did the paperclip test to get it to start again.

I did all of this and it didn't help. http://www.tomshardware.com/forum/261145-31-perform-steps-posting-post-boot-video-problems

The fans still just started then stopped.

So I purchased a mobo speaker. No beeps.

From there being no beeps I read that it's probably a PSU issue which did not surprise me. I don't currently have the tool to test it, but I picked up a Dynex 520 watt PSU hoping it would solve the issue. I plugged it in and now all the fans spin up just fine, but still no beeps and no boot.

And now I have no idea what to do. Any help would be hugely appreciated. I'm hoping it's not the motherboard or CPU so I don't have to wait for a new one to get here, but I'm worried that's the only possible solution.

Edit* I am using a asrock Z87 PRO4 mobo. My friend said some motherboards have a special plug called "OC power input" that's required to boot. I'm not seeing it on mine but that doesn't mean it's not there.
 
The first thing to check is that the cpu you bought is supported by the motherboard.

You can do this by going to the maker of the board, and entering it`s model number on there website.

It will list the cpu`s supported, and what version of the bios firmware must be present on the motherboard in order for it to work with the cpu model you have.

The plug your friend is talking about is an eight pin block from the PSU to the motherboard.

Your eight pin block is located on the board at the top edge
Above the cooling dissipation block, in black.

This must be plugged in as the board will only part power up and not post.

See the picture for the eight pin block in question.
It should work fine once connected if you have not. All the best for 2014.

I'm using an i5-4670. Looks like it's supported. Good idea though. I have the black 8 pin power connector plugged in also. It's two 4 pin connectors on the new PSU. I checked and left and right are on the correct side. Under the bios list on the chart it just says "all". I'm not sure what this means.
