So I bought a new motherboard because I thought my old one went bad, the new one MSI MPG Z390 GAMING PLUS the old one is Gigabyte Z370 AORUS Gaming 7
and hooked my G.SKILL TridentZ RGB Series 16GB (2 x 8GB) 288-Pin DDR4 3000MHz (PC4 24000) Desktop Memory Model F4-3000C16D-16GTZR to it but when I turn it on there is no signal to monitor and CPU EZ Debug LED is on?

the MSI website (https://us.msi.com/Motherboard/support/MPG-Z390-GAMING-PLUS#support-mem-6) says the ram is not compatible but the G.SKILL and pcpartpicker says it is.

My question is, was my CPU dead all along or is the RAM the issue? I wanna know if I should buy new RAMs to fit the motherboard or replace the CPU?

CPU: Intel Core i7-8700K
Cooler: NZXT Kraken X62 Liquid CPU Cooler
Motherboard: MSI MPG Z390 Gaming Plus LGA1151
Ram: G.Skill Trident Z RGB 32 GB
SSD/HDD: 1TB Samsung 970 Evo
GPU: GTX 1080ti
PSU: EVGA supernova g3 850 OS: W10

Per the manual, if the CPU EZ Debug LED is on " indicates CPU is not detected or fail"
https://download.msi.com/archive/mnu_exe/mb/E7B51v11.pdf
Tour RAM is clearly indicated as compatible on the GSkill configurator; it is not on the mobo's QVL simply because MSI did not tested this exact reference, not because it is incompatible.
I see no reason to implicate your RAM in the problem
