Hello, I am new to this forum, but i do follow linustechtips on YouTube whatsoever. so I recently chose some parts to build a PC for my friend. I built a lot of computers in my life but this one seems to give me a headache since i can't find the solution for it.
The specs are listed below:
CPU - Intel Core i5-7600K 3.8 GHz QuadCore 6 MB Cache CPU
GPU - MSI GTX 1070 GAMING X 8G GeForce 8 GB GDDR5
MOBO - MSI Z270 SLI PLUS
HDD - WD Blue 1TB Desktop Hard Disk Drive
SSD - No money yet
PSU - Corsair 550 W RM550x Series 80 PLUS Gold Full Modular ATX Power Supply Unit
CPU Cooler - Cooler Master Seidon 240V CPU AIO
RAM - Corsair CMK8GX4M2A2400C14 8 GB (2 x 4 GB) Vengeance LPX DDR4 Memory Kit (Questionable, IS IT COMPATIBLE?) - Probably that's why is not even posting?
The error i am getting is the EZ Debug CPU Light is always WHITE ON. Constantly; not flashing, not blinking but WHITE. The connected monitor does not have ani signal "NO INPUT SIGNAL". Can't see BIOS, computer not POST-ing. I can't seem to find WHY. Things that i have already tried but they did not work!
- Tested the monitor to my macbook and pc. Monitor works fine via HDMI 2.0 and DisplayPort
- Tried different cables such as VGA, DVI-D, HDMI 2.0 and DisplayPort (same result, no input signal)
- Replaced previous gigabyte motherboard with this one, computer not posting
- Replaced CPU with another one, I RMA'd the previous one I thought its DOA. Welp,
- Tested the power supply. All cables are supplying the correct amount of voltages
- Changed 4x4 CPU cable and reconnected
- Re-attached all motherboard cables
- Breadboarding starting with one stick of ram, for each dimm slot, only cpu and 24 pin ATX cable connected / also with CPU fan connected in case motherboard has some kind of safety lock to prevent cpu overheating which could probably stop the POST process or even booting.
- Pushed all the RAM memory to the specified slots, i have read the manual and connected them on the required dimm slots for a dual channel config
- Tried it with GPU and without GPU. Connected the video cables straight to mobo.
- Motherboard PINS are NOT bent. I checked and rechecked and rechecked. It's new. i got it today.
- CPU sits very nicely and everything is pushed properly
- Tried different power sockets
- Tried to turn on outside and inside the PC case.
- Tried it to boot without the HDD connected
- Tried to boot with and without the AIO cpu cooler installed (AFAIK for a few seconds CPU wont overheat, just wanted to see if it POST-s so i could check the BIOS)
- Checked carefully the P+|P-|PWR SW to be connected to corresponding motherboard PINS
- While computer unplugged from PSU, disconnected from power socket, cleared the CMOS
- Reseated the BIOS battery
- I can't update BIOS in case it came with an outdated one because unfortunately I do not have any spare CPU's....
I am actually haunted by this darn error. All i could think is the bloody RAM not being compatible with my MOBO? Any suggestions? Thanks.

EDIT:
- Tried to swap RAM
- Also checked if the PSU is turned ON by the switch.
