my motherboard is an asus prime b450m-k, so i turn the pc off properly nothing really there the fans are down everything is turned off, then there are these cool lightings on the board that light yellow they stay lightened until i unplug the power cable from the outlet a few seconds later the lightings completely turn off and make a weird sound its like a sound that u hear when u remove the psu cable without turning off the pc it just clicks, and it got me confused
