Question New Build, Cpu light on, no display

[shoutsnj]

CPU - Intel I9 12900K
MB - MSI MEG Z690 ACE
GC - EVGA GeForce RTX 3090 Ti
Mem - G.Skill Trident Z5 RGB Series 32GB (2 x 16GB) 288-Pin SDRAM DDR5 6400 (PC5-51200) CL32-39-39-102 1.40V Dual Channel Desktop Memory Model F5-6400J3239G16GA2-TZ5RK (Matte Black)

When I turn get CPU warning light. MSI tech said Cpu problem, so I got a new I9 and have the exact same problem! Red CPU warning light immediately, doesn't turn off.

Have tried removing ram, resetting cmos, disconnecting graphics card, multiple restarts. No display.

Any ideas?

Welcome to the forums, newcomer!

Make and model of your PSU? Did you try powering the system breadboarded with at least 1 stick of ram and no discrete GPU? How are you cooling that processor? Also, might want to inspect the CPU socket for any bent or broken pins.

GSKILL 4x8 GB DDR5
Please add a link to the ram kit you're using.

Edited to add, I will check pins, thanks.

Don't see anything, guess I should just return the motherboard?
