I've checked the threads and can't find an issue exactly like mine. I have a corsair C70 case (awesome btw) and one of the USB ports on the front causes the computer to totally freeze when ANYTHING is plugged in. The USB port right next to it works just fine. When the freeze happens, the screen stays on but it is stuck and will not respond to anything but a hard shutdown. I assume it is a grounding issue but I do not know where to start. Please help me.
