Question ASUS X570 TuF Gaming WiFI and random VGA light & no POST?

[LiveLongVoyager]

Most of the time booting up is no issue, but sometimes when i boot i'll get a VGA light on mobo, but no display. Usually restarting PC once does the trick to fix it and no problems from there, but the recent time it happened, i had to hit restart twice and now i'm worried. I'll know i'll get a VGA light/no post when i first boot on PC and MOBO LED light is on yellow (RAM) and the light on the GPU itself wont turn on past that point. When it doesnt turn on, it goes past red (CPU) and gets stuck on white (VGA). SOMETIMES if i wait a little bit, it seems to to go back to yellow (RAM) and GPU light will turn on and everything will post normally.

Is this a BIOS issue? Im on version 1405
