problem at start screen

[Jose Fajis]

Hi, I just had a problem with my MBP.
When I turn it on, it sent me to the Login Screen (which can't happen because I never enabled that feature) so I wrote my password and the light-blue screen appears and after 3 seconds after it goes back to the login screen.
Happens the same if I click restart or shut down. The only way out I could think was to keep the power button pressed, it fixed it.
Any idea what could this be?

Thank You

There are a few possibilities, not all of which paint a pretty picture of your hard drive's continued reliability. Make or update a backup right away.

It's possible that you're looking at simple permissions issues, although why they'd fix themselves when you restarted I don't know. A permission repair is a good place to start, anyway.

Where can I make that permission repair? (I'm kind of new in the mac world)

Select your hard drive and hit 'Repair Permissions". Takes a few minutes.
