I have a computer here which was passed onto me because the keyboard was not working and the mouse was intermittent. It is running Windows Xp Pro. I booted it into windows and checked the driver seemed ok, which it was. I have since changed the drivers but now neither keyboard or mouse work. I know both are OK as they are from another machine I have here. I have tried going into safe mode but still no success. I think it is a problem with windows because the keyboard works for me to access the bios and also if I run my Micro 2000 Microscope software both keyboard and mouse work OK, hence my thoughts that it may be a windows problem. I have since tried to do a repair install of windows but of course I have a problem when it asks me for the cd-key which is as far as I can go. At this moment I suspect my only course of action is to reload windows completely unles any of you guys have any other suggestion.
