Is My Motherboard Broken?

So I just had my friend bring his new parts over unopened and I built it for him, but I'm having an issue with the motherboard, or at least I'm pretty sure.

When I went to do the first test boot, it all turned on, and then shut off within about 7 seconds, and would repeat. The fans also looked like they were spinning at maybe 65% of normal speed. It also didn't run any display, not even a mobo splash screen. Before coming on here, I went through the usual RAM swapping and power supply swapping to troubleshoot it. No matter what, it would just shut off and restart, I even took it out of the case to keep it free of any shorting possibility and still no luck. I swapped wall sockets, I took the Hyper 212 off to see if maybe there was something causing a short, but still nothing.

So far I'm pretty convinced that something isn't working properly in the motherboard. I couldn't do a cpu swap because it's an i7 6800k and I don't have a 2011 motherboard.

But I think like it's unlikely that it's going to be the CPU considering that the fans weren't spinning at normal speed. If you have any suggestions, please let me know. I told him it was more than likely a mobo issue, and that he should return it through newegg for a replacement. But I'd rather be 100% right and not worry about it being something totally different. Thanks.
 
First of all do check that if the board has a bios jumper pins on it to reset the board to factory defaults that the two pins that should be bridged by the jumper cap are set to normal bios operation mode, and not left to constantly reset the bios.

That the 24 12v power block from the psu is connected to the board, and you have also connected to the motherboard the eight pin 12v Eps connector from your Psu.

If the board has on board video connect the monitor lead you have to the video output ports of it first of all.
Any Pci-e based graphics card used in the system, make sure it has the correct Pci-e power connectors from the Psu of the system fitted to it.

Check the manual for the correct population order of dimm slots that must be used if you have a matched pair of memory sticks, as placed in the wrong memory slots will result in the board not posting.

I said I tried booting without a gpu already and it still shuts it self off and restarts. Regardless of whether or not it has on-board video, the pc would still stay on. Like I said it's an i7 6800k, the board obviously has onboard video. You aren't looking at the context of the situation.

Do you actually think I haven't tried checking cable inputs a million times? There's obviously another issue here.
