hi guys,i have a problem with my mouse. after booting my pc up,(i have xp) when windows loads and it gives u the list of users,if my mouse(which is plugged into a usb port) is plugged in,the pc just freezes and wont load up. but if i unplug the mouse and plug it back in once the desktop has loaded then it works fine. what do you think the problem is and how do i sort it?
