Question HELP! New build, CPU led lit on motherboard, no POST, no display ?

Apr 17, 2021
Hello, I need help.
I recently bought some new parts for my PC because my old stuff (mobo and cpu) were dying, the new parts are:
  1. Intel i5 10600KF 10th gen
  2. Corsair H100i RGB Cpu Cooler
  3. Asus ROG Strix B460-H Gaming Motherboard
  4. PSU Corsair RM650
I combined with some old stuff of mine:
  • Galax GTX 1660 6gb DDR5
  • RAM Corsair Vengeance Pro RGB 2x8
  • SSD Adata M2 500gb
  • Seagate Barracude 2TB SATA3
  • NZXT Phantom 530 case
However, after I installed everything and pressed the power button, it won't boot/load. No display on my monitor, all fans are spinning, GPU fans work normally (spins and then stopped, but I figured that it will only spin again under heavy load), no beep. I noticed that the CPU led on the board was lit red.

What I have done:
  • tried the cpu (without cooler), gpu, and ram on another board = working like a charm, get past bios, no issue.
  • tried on the new board (without cooler) = still not working, cpu lit red on motherboard.
  • tried one stick of RAM, tries different slot, still the same.
Please help

This is when I try on a diff board:

This is when I try on the new board:

As you can see, on the new board it there is no screen at all and red light from CPU on motherboard, the orange was RAM but only blinking
