Everything had been working fine but this morning when I got on, typed in my password I got a message that says "The user profile service service failed the logon. User profile cannot be loaded." This is an acer that is approximately 6-7 years old. I tried to do the fix that someone mentioned, re: removing the mother board battery, but cannot get to the mother board. If someone has a way to fix this I would really appreciate it. I am using my husband's computer.
