No boot / bios or beep... yet everything else seems fine?

[Lezenko]

Hi guys hope all is well. Got a bit of a strange one here if I'm honest.

Building a rig for a colleague who's just put a fair bit into it. Specs are as follows:
Intel i5 8600k
Aorus z370 Gaming 7
HyperX Predator 8gb 3000mhz (x2) (unsupported it seems but read below)
Nvidia 1080 by Gigabyte
Samsung Evo SSD.

So the rig was built, everything installed. Hit the power button and the motherboard lights up, the cpu and gpu fans are spinning, everything looks grand. Only thing is there is no visuals on the screen and the system reboots after i'd say 20 - 30 seconds and it's caught in a loop.

The ram in question isn't listed on the supported memory for the mobo, not usually a biggy however the manufacturers site claims that for it to be set to 3k mhz it needs to be O.C'd.

I didn't have a spare set of RAM on me to test it as we built it at his house but that was my number 1 culprit.

I'm just wondering if or what else it could be causing the issue?

Thanks guys!

Clear CMOS and remove the video card, plug the monitor into the motherboard.
Try one stick of memory at a time in each slot if no boot with the first stick in sny of the 4 slots try the other stick the same way.

Haven't tried the CMOS admitedly, did try without the video card and going direct. Also tried one memory stick by itself (tried this on both) on the first and second slot and still nada.
