Interactive logon process initialization has failed on Windows 7

[coolswathi]

Hi,

I have a laptop which has stopped running since yesterday evening and gives me this error on a dialog box due to which I am not able to logon to the system. When I restart my machine, it gives me 4 options i.e.

Safe Mode
Safe Mode with Networks
Safe Mode using command prompt
Logon normally

I tried all 4 of them if atleast any of these allows me to login, but none worked. I referred to the solutions and fixes available on the internet, but all of them says that I need to press F8, enter into a safe mode and operate the issue from there. But even pressing F8 doesn't make any change.

Did anybody faced same issue? How do I resolve this?

Thanks.
