Hey guys, i've been running vista home premium for a few months now without any problems. However recently i have tried to add a few new user accounts and i have run into a little problem. It allows me to create the user, but when i try to login it just sits at a pretty blank blue screen with the mouse cursor..i've had it sit overnight thinking it was just loading settings/preparing the desktop, but nope nothing! not sure what i should do. Anyone have any similar problems?
