Windows could not connct to the user profile service.

Whenever I attempt to log onto my computer, it gives me an error message:

"Failed to connect to a windows service. Windows could not connect to the user profile service service. This problem prevents standard users from logging on to the system. As an administrative user, you can review the system event log for details about why the service didn't respond."

I have no idea what is causing this and I have searched online to no avail, my computer has been out for about three months now. The problem prevents me from connecting to the internet, my personal profile has been removed and the settings are back at default. Please help me :(?

## Symptoms ##

--------------------

When you log on to a Windows 7-based or a Windows Vista-based computer by using a temporary profile, you receive the following error message:

The User Profile Service failed the logon. User profile cannot be loaded.

## Resolution ##

--------------------

Occasionally, Windows might not read your user profile correctly, such as if your antivirus software is scanning your computer while you try to log on. Before you follow the methods here, try restarting your computer and logging on with your user account again to resolve the issue. If you restart your computer and it does not resolve this issue, use the following methods to resolve this issue.  
  
  
Note You must be able to log on to an administrator account to fix your user profile or copy your data to a new account. Before you resolve the issue, log on to Windows by using another account that has administrative permissions, or restart in safe mode to log on with the built-in administrator account.
