It's not really clear (to me) what you are describing.

It is possible there multiple issues as you mention a log in loop, data loss, update problems and provide a snippet of information about a graphics device. We cannot see what is happening and need a clear description of the problem.

If there are multiple problems it is probably best to make a post for each one.
