Postgresql x64 9.1 service error occurred

Hi DBA, when I am trying to install PostgreSQL 9.1 got a peculiar error message, which I never experienced before. During the procedure the system restarts, I didn’t see the Postgresql on startup. I got this error message. So I was trying to retype the password in the server properties, but the problem persists. Help DBA’s?

Windows could not start the postgresql-x64-9.1 – PostgreSQL Server 9.1 service on Local Computer.
Error 1069: The service did not start due to a logon failure.
