so i just go done installing my new PSU, and i wanted to boot up and soo if everything is working properly. i left the sides of my case off because if something did go wrong its easier to get to. when i was booting up i noticed 3 red lights were on, but they went away and i was at my login screen. i looked to see if there is a title of what the lights are on my motherboard is, but i didnt see any. my pc works fine all my componets, but i am really curious what this is, i didnt find anything like this online. are the lights normal i just never noticed them bacause my case sides were on?
