I've been given a pc to look at and one of the problems with it is that it is coming up with this while the computer is idle or active seemingly randomly.
There is a usb keyboard and mouse, and a pda cradle connected. Since the pda cradle is not an active usb device I have ruled that out for now. Obviously I have to have a keyboard and mouse connected, so is my next step to disable usb ports in device manager one by one until the problem goes away or is there another fix to this problem?
