So, I am hooking up all the cables to the back of my computer, when i went to plug in the last cable, I noticed this red glow coming from the motherboard! this might not be so alarming if i had plugged the computer in (the motherboard has a couple of LED light strips running across it), but the power supply is UNPLUGGED! I started unplugging cables one by one, to try to find out where the power was coming from. it turned out to be a 10 socket USB 2.0 hub. the power is back feeding from that hub (it has a small power supply of its own) into my motherboard. might this be a serious problem? i just replaced the motherboard because the original one died. might this back feed be the cause? or am I freaking out for no reason?
