Sorry about the late reply.
@Tveblen - In the end we determined it hardware failure. I wish I could have checked the BIOS, its kind of hard when the computer is close to eight hours away via Plane :P.
@GregRocker - Yep we had tried a known working mouse and keyboard.
In the end I did something stupid and changed the permissions on the system32/drivers to our administrator account and it made one of the two unknown devices work, however it wouldnt install any of the attached devices.
In the end I determined it to either be Hardware failure or Os corruption since it wouldnt even install Windows updates without failure.
Given the pc has just been giving us issues and is relativity new were replacing it.
Thanks for all your help mates
