I went over to a friend's house with pc everything was fine until we got home now my peripheralspecialty rent detected by pc and I get no video output tried two monitors with two cables so I though maybe graphics but then my keyboard has no lights and neither does my mouse, yet when I plugged my phone in i still got power is my Northbridge/Southbridge fried? Because this makes no sense to me for it to be all of the sudden like this
