I have a client running Windows XP on a machine that controls various cameras and a Sonos as well as gate controls. That's about all it does. I ran into an issue where at the Windows logon screen, the mouse pointer flies across the screen erratically and the keyboard cannot input the password because it flashes like there is a key stuck and pops me right out of the password field. This happens even if I boot without the mouse installed (the pointer is still going crazy) or without the keyboard (I thought there might be a stuck key). Safe mode works fine. Nothing had changed on the machine since the last time it was accessed a week ago and everything was fine. In safe mode the event log showed no errors. There was nothing suspicious in the msconfig either. The machine is only used to control the devices and is not directly accessed for anything but configuration. Has anyone seen this before?
