Win 7 login problem

[kelak]

Hi friends, today I got a bad problem from Windows 7 login process. when I want to login with my password, it shows an error message like below;
"The user profile service failed the login. user profile cannot be loaded."
As my known, my laptop have the two main problem. First, I installed too many softwares in my laptop. Second, I have no antivirus. So what you think, what is the main problem behind this?

Try this

Error message: "The User Profile Service failed the logon. User profile cannot be loaded”, when logging on to Windows 7 or Windows Vista

Try to login via safe mode then do system restore to a date before the problem occured.
Also try to boot from Dvd and use Repair Windows option.
