Many thanks for your suggestion. I may give it a go, but I am a bit reluctant to try as I have not had any luck with other solutions, probably because I am doing them wrong...
Well you could look at device manager and let me know what is listed for your USB host controller. I am under the impression that you are using a USB keyboard and mouse.
I am using a wireless keyboard and mouse, but am having difficulty getting access to anything on the computer due to the password problem. I have a tech guy looking at it now and wil let you know what results.
