Hey guys I'm trying to get some help finding out what this orange led at the bottom right of my motherboard is. I have looked all through the manual for the mobo but it says nothing about them and the mobo doesn't have anything beside the led to indicatewhat it is. I built this system approximately 2 years ago and it consists of an i5 8400, asus rog strix h370-i motherboard, 16gb of xpg 2666 memory, gigabyte gtx 1060, and an evga 450w psu. The system has been running perfect since I built it until it randomly shut off a few days ago. The motherboard rgb still lights up but when I press the power button it does nothing. To troubleshoot i have swapped memory, cpu, gpu, and psu into another system I have to verify that they work and I have swapped the stuff from they other system into this one but it still does nothing when the power button is pressed. I have unhooked the header for the power button and jumped the pins and it does nothing. I have jumped the pins to reset bios settings but it didn't help. I'm thinking my motherboard is dead. I'm just trying to figure out if the orange led at the bottom of the mobo is trying to tell me anything. I can't recall ever noticing it before they system quit working. Any help would be greatly appreciated.
