So I moved a Dell xps 9100 out of its stock case and into a zalman z9u3. After hooking it all up the computer boots to a bios boot check which says FRONT USB NOT CONNECTED. If I press f1 it then boots windows and everything is fine but the front USB ports do not function. In the Device manager it shows that the USB hub is connected but it says it cannot start. If I plug a USB device into the ports it beeps in windows but nothing happens after that. Anyone have any ideas?
