Hi there.
I've just brought a new motherbaord amd athlon 3200,
Connected the PC together and was working fine.
Bean installing windows, all was working fine but now none of the usb drives are working.
Anything connected by usb does not work.
The on board usb don't work and the usb connected off the board don't work now either.
I've even added external usb slots, they don't even work?
Does anyone know what they problem is?

It is possible that the connectors from the usb port to the board are backwards, see if possible and if is, turn connectors around on the pins - pin 1 will be positve
