New computer not POSTing, DRAM LED

[Jay K.]

Specs:

Motherboard: MSI B760 GAMING PLUS WIFI

CPU: Intel Core i5-12600K 10C/16T 4.9GHz LGA1700 

GPU: MSI GeForce RTX 3060 VENTUS 2X 12G OC 

RAM: CORSAIR VENGEANCE DDR5 RAM 32GB (2x16GB) 6000MHz CL36 Intel XMP iCUE Compatible

PSU: MSI MAG A750GL PCIE5 Power Supply Unit, 750W, 80 Plus Gold

CPU Cooler: DeepCool AK500

M.2 SSD: Crucial P3 1TB M.2 PCIe Gen3

 

I have plugged in my motherboard 24 pin ATX, CPU PWR 1, and GPU PCIE into the PSU. 

 

When I turn on the system it goes between red CPU and orange DRAM LEDs before staying on a solid yellow DRAM EZ debug LED.

 

I have tried reseating the CPU, different RAM sticks, different RAM slots. I don't have a second DDR5-Compatible motherboard to test with, or a second modular PSU.

 

Any ideas?

How long are you waiting for it to boot?

Try using individual RAM sticks or try them in different channels.

Only other thing I'm aware of that can cause boot issues is a cooler mount that is uneven or too tight/too loose.

 

Did you try the onboard with the graphics card pulled? Preferably using HDMI.
