So, I am not new at computer builds for starters. Second, sorry if this thread is in the wrong area.

Okay, so I installed all of the new components and turned on the power and a light to the left of the SATA connector surrounding the "AsRock" labeled block turned on white. It then proceeded to turn red and flash. I booted anyways and no screen came up (display connected to GPU) and the computer proceed to go into a cycle of turning off and back on.

I though it may be the RAM placement. I do not think so now. I tired slots 1 and 3 and 2 and 4. Neither cause anything different, expect when in slots 2 and 4 the RAM in DIMM 4 does not light up. I am now in slots 1 and 3. I also tried booting without a GPU, which changed nothing.

Thank you so much in advance.

Try starting the board outside the case. Check also the CPU socket for bent pins.

There maybe a list of fault codes in the motherboard manual.

It doesn't sound like RAM as it wouldn't usually loop. Try with one stick of RAM in slot 1 and disconnect everything...test adding each device one at a time and by process of elimination you'll find the problem...

Sounds like it's not seeing the CPU--that's what usually causes the on-runs a few seconds-off-wait a few seconds-on cycle. Do you have a speaker connected to the motherboard? A bad/badly seated CPU will give you 4 beeps between cycles (I think).

BTW, I assume you mean a AsRock Z370 Killer SLI/AC

Try entering the UEFI SETUP UTILITY by pressing <F2> or <Del> right after you power on the computer.

I think the red blinking may just be the RGB on the board. I looked at a thread on the AsRock website and that seemed to be the case. The powering on and off may be the main issue. I am currently trying more stuff.

Monitor shows no picture.

I have no speaker, but just checked the CPU. No bent pins and it is seated properly.

Okay guys! Great news! It posted. The problem was the silly cooling system. It was not actually pumping and was disrupting a contact point.
