Vista - The User Profile Service service failed the logon. User Profile cannot be loaded

I have a very bad problem with my PC. It started yesterday and the vista system repair came up and scanned my computer. When it finished I clicked finish and my PC restarted then it did it again..and again...and again.
Then I went into safe mode and virus scanned everything but came up with nothing. So I restarted my PC and it said The user profile service failed the logon. User profile cannot be loaded. So I clicked ok then my user account came up somehow. I clicked it and it took me to desktop except that half of my programs were gone and like nothing worked, all my documents, downloads, pictures were all gone. I can't do anything on that computer, can anyone help please??(I have googled it but none of the solutions work so I want to find an answer specific to my problem)

Do you have a backup to restore from? have you run system file checker (sfc /scannow)? could you tell us about your system by putting your system specs (lower left corner) so that we know what kind of hardware you have

Hello, and welcome to Vista Forms.

Have you already tried everything in this tutorial below including the yellow TIP box at the top?
