Static Discharge at USB ports results in PC crash
Posted on 2011-03-21
So, I built an AMD based machine for my client. Everything seemed fine at the shop. When I delivered the machine to the client everything seemed fine. The problem started to occur when the client attempted to inset a flash drive into the front USB port.
A small static discharge cause the machine to turn off. If the case is touched first, an audible and visable static shock is observed, then the USB can be inserted with no issues.
I have replaced the case, the power supply, the motherboard and the problem still exists. I even connected the ground wires from the USB ports directly to the case and it still crashed.
I am at my wits end here. Ideas?
