Logged in as temp user each time I log back in. How do I prevent this?

Each time I try to log in to windows for the past few weeks I've gotten a message that I've been logged in to a temporary user, I've been able to recover from each of these (a total of five different times). The first few times I was able to use a system restore to bring by my desktop and full functionality. The most recent time I could not restore, the restore point itself was not working. I was able to bring back functionality by doing a regedit on the profile.

I'm interested in learning what is causing this problem, and how to prevent it from happening again. So far I have changed my current settings to update my restore point more often.

I have noticed something that may be related to this. I have a pop up notification text box that appears and disappears too fast to be able to read any text on it. I've tried to keep the notification area icons window open to see if anything appears there, but nothing does. All icons are marked as show Icons and Notifications to try and eliminate these as the culprits.
