Unable to logon to Windows 7

[maizenbluedoc]

When atempting to logon to Windows 7, the following appears: The User Profile Services services failed the logon. Subsequent logon attempts created the following: The user profile cannot be loaded. I attempted drpressing F8 repeatedly and the same message appears. I cannot log on, so there isn't any function that I can initiate to correct this. Any suggestions?
