of most of the posters on here and have AppleCare covering this MacBook Pro.
Even if you didn't, this machine should still be under warranty and you should immediately phone Apple and report this problem. Ask for a case number.
If they cannot fix it over the phone, or it gets fixed temporarily, and then fails again, you have documented evidence that the problem started BEFORE the warranty ran out.

Read this, log out and go phone Apple.
