Lights on motheboard? What are they?

[mAAns]

I have a "Asus ROG Strix B350-F Gaming" and on the top left corner there are four lights (Green, yellow, red, and white)

When I start my computer they sometimes lit up. In some order that I forgot now. And then they stop and nothing else happens, the system works as normal.

Also somtimes my computer crashes and then these light light up and I get realy confused. 

 

pls explain what they mean.

It's called ''ASUS Q-LED''

(CPU, DRAM, VGA, Boot Device LED)

There you go. 

 

Post LED.

When a hardware error occurs, one of those lights will stay lit.

They indicate errors for GPU / RAM / CPU / Storage. Not sure what they exactly mean but this is the only things I can find. Sometimes they have text next to the light telling what it is.

Maybe this will shed some light on what it is and how it works.
I checked in the manual but only 1 mention of Q-led and nothing else. Bit weak of Asus if you ask me.
