Hi Guys,

My machine has 4 usb ports on the back and 2 on the front connected to the motherboard by one of those connector blocks.

Anyway.
Ive reinstalled windows twice.
The drivers are installed as windows sayas it has 4 usb controllers and 4 root hubs, all showing NOTHING connected but working ok.

No hardware in the device manager with a fault.

This is where it gets odd.
If i plug a mouse, memory stick , anything into ANY port on the pc .
It gets power but the pc does nothing with it ( tried 2 mice neither work )

Does anyone have any ideas what could be causing this?

I downloaded the Intel USB checker and it says the PC's USB is working correctly.
 
leave it plugged in long enough for the system to detect it.

or

run the add new hardware wizard
