SQL Server Agent (MSSQLSERVER) service is failing to start

Hi All,

I am using SQL Server 2008 R2 Express edition. When i start SQL Server Agent (MSSQLSERVER) service it is failing to start and gives the below error.

On analyzing the Event logs i found the below event.

The SQL Server Agent (MSSQLSERVER) service terminated unexpectedly.  It has done this 14 time(s).

Event id 7034
Event source: Service Control Manager.

I opened the SQL server configuration manager to change the service account and start the service, But that is also failing and it is giving the below error.

Can any one help in this issue ?
