New CPU not POSTing

[Holy Mike B]

Current(working) specs:

 

Motherboard: Z87-K

CPU: Intel i7 4770K @ 3.5 GHz

RAM: adata XPG V2 16GB DDr3 2400 PC3

GPU: EVGA Nvidia GTX 980ti 6GB

 

I recently purchased an Intel i7 4790K as I wanted to upgrade the CPU in my pc. I got it, installed it, aaaaaaand I had no signal going to my monitors or anything plugged into the USB ports. As I understand it, it is not POSTing. I've tried pretty much everything I can think of. I had the help of a friend who tried his hardest to help me get it working, but nothing worked. Here is a list of everything I've done so far:

 

I've cleaned out the case, I did the whole "hold the power button for 15+ seconds with the computer unplugged to get any excess power out" thing, I updated the BIOS for my motherboard, I tried booting without RAM, I tried booting with just one RAM stick, I tried using my old 8GB(2x4) RAM sticks, I've double checked to make sure that all the appropriate cables are plugged in, I've checked all the pins for the CPU to ensure they aren't bent. Nothing has worked so far.

 

What I really don't understand is that everything starts up when I turn the PC on. The GPU, fans, water cooler, hard drive, SSD, etc. But it just refuses to post. I just can't understand what is wrong. It doesn't seem that my motherboard is damaged or malfunctioning considering everything runs just fine with my 4770K installed. Does anyone have any other suggestions to get it to post, or am I just SoL?

I wasn't quite sure about this one, and forgive me if I am wrong, but, considering you just bought it, could it be a dead on arrival?

That was what we thought, too. So, I sent it back, got another one, but it too will not POST. Sorry, I meant to put that in the original post.

What power supply do you have? I'm not sure, but it could be a problem with the ports on the psu, or an issue of not enough wattage. Could it be the cables?

I have a OCZ 700 watt power supply. So, as far as I'm aware, I should have more than enough power to run it. And, from what I can see, none of the cables seem damaged or anything.

I'd check the slot on the mobo for the cpu, and test with different cables if possible.

Alright, I'll have to give that a try. Though, it just seems weird that my 4770K works without a problem and the 4790K doesn't.

How did you do the BIOS update? In my experience Asus Z87 boards are stupidly finicky when it comes to accepting a good BIOS flash. I fought with a Z87-A for several hours, finally had to flash it through the Asus Windows utility with my 4670k in place before it would accept a 4690k. And that was after flashing through the UEFI from a USB key many, many times.

Yeah, I updated it using EZ flash through the BIOS utility. I read an article from a guy who had the exact same problem with the same motherboard and used the same BIOS version that he used which was a somewhat older version. I had tried using the newest version as well, but that didn't work.

It definitely sounds like the update isn't quite sticking, which is the issue I had as well. The BIOS showed the right version, but certain things were off and a 4690k wouldn't post, but the older 4670k worked just fine.

 

Try a different flash method, and even a different USB stick.

Well, I've also tried using ASUS' BIOS updater tool to do it. It requires the Intel Management Engine Interface driver to be installed, which it is, but when I run the updater it won't detect it, and I have no idea why.
