Hello

I am an idiot who decided installing a new CPU (i9 9900K) and a new CPU cooler (iCue H100i RGB PRO XT) would be easy enough to do without needing a specialist to help me!

I was wrong. This thing is birked. As I moved recently I don't have the original PSU box with all the cables nor the motherboard with those cables either. Just the ones already in my PC. So I unhooked a USB header to put in the new CPU cooler, pulled a SATA Power off one my HDD's and placed as instructed the CPU cooler into the case, installed the new i9, and I didn't get fan-spin. In fact when I flicked the rear power switch, what normally happens is the RGB flashes on and I hit the power button and it all turns on. What happened this time was, I flicked the power on and nothing would happen, then off and everything would surge with power. fan-spin, lights, everything. For about half a second and then it cut out. Front Power button doing absolutely nothing

At this point I have tried every combination of the swapped items present. Including the original set-up with no cooler just Intel's stock cooler, as well as the original CPU (that's where I'm at now)

So here's the speclist as it stands last I turned it on and it worked:

Gigabyte Aeorus Z370 Ultra Gaming 7 (Bios F16b)
i7 8700K Intel CPU
4x DDR4 HyperX 4 GB RAM
2x Gigabyte GTX 1080 (no SLI as the cable didn't show up till today)
EVO 960 Samsung M.2 NVME SSD 500 GB (Boot disk)

And the new parts:
LINKUP SLI Cable
i9 9900K
iCue H100i RGB PRO XT

That's it. I can provide pictures of the inside of this thing as it stands. On the original i7, but it will not boot at all.

Did you determine if the Gigabyte Z370 Aorus Ultra Gaming 7 motherboard supports using the Intel Core i9-9900K CPU?

Did you determine if a BIOS update is needed BEFORE removing the Intel Core i7-8700K CPU and installing the Intel Core i9-9900K CPU?

Solved.

It was a loose motherboard power connector which created the exact loose connection to trigger the RGB and fan flash identical to power being turned on regularly, but would not allow it to turn on.
