MSI Z890 GAMING PLUS will not POST

[aydamuch15e802e9]

My new build will not POST.
The CPU EZ Debug LED comes on red solid, goes off and the DRAM LED comes on steady.
I tested a single RAM stick in slot DIMMA2, loosen the CPU cooler mounting pressure, and inspect the LGA1851 socket pins.
I have flashed the BIOS and upgraded to the latest BIOS. I have cleared CMOS.


My build is:
Intel Core Ultra 7 270K Plus
Thermalright Peerless Assassin 120 SE
Crucial T500 W/Heatsink 1 TB M.2-2280 PCIe 4.0 X4 NVME Solid State Drive
Crucial Pro 64 GB (2 x 32 GB) DDR5-5600 CL46 Memory
MSI Z890 GAMING PLUS WIFI ATX LGA1851 Motherboard

WHAT TO DO?

Hi
Have you tried leaving it on for 10 minutes? Sometimes first POST, with memory training, may take a bit more time than 10 seconds.
Also try each stick in each RAM slot.

Have you connected all power cables for the CPU?
