I am trying to fix my dads computer it is running Windows XP Home. When I click on any of the login names (his or mine) at the Windows XP login screen, it looks like I am going to be logged in, then it says saving data and logs me out, taking me back to the original login screen. Has anyone seen this or know of a way to fix it. I really am in need of a fix. I have tried several things. My dad needs his computer back on for some business stuff.
