Question Yellow light w/ RAM on asus z370-a prime tried different RAM sticks. How fix?

[sunken_swimmer]

Setup:
CPU: i5 8500
MOBO: ASUS z370-a prime
GPU: MSI 980ti
RAM: HyperX predator DDR4 2666MHz 2x8gb
PSU: 750W

I recently upgraded my CPU, RAM, and Motherboard, and after putting them in, without changing anything in terms of wiring, the yellow RAM light is lit, and the computer does not boot on. (the LEDs and fans do turn on)

Extra: the power button does not turn it back off


Thank you in advance for help.

You need to refer to the motherboard's User Guide/Manual to find out what that yellow RAM light means.

Do verify that I found the applicable User Guide.

Double check the RAM installation per Pages 1-5 and 1-6.

You should also visit the ASUS website to ensure that the RAM modules that you are using are indeed supported by the motherboard.

Turns out that the two DIMM slots furthest to the right do not work, thank you for all responses. Really happy to be back gaming!!
