When i click on connect button it gives me this error msg "Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) "

         I searched on google i find some suggestion but its not working , then i check in
configuration tool -> sql server configuration manager ->  sql server (sqlexpress)
here services of sql has stopped  when i try to start services of sql server it gives me another error ....  "Request failed and service did not start in timely fashion. Consult the event log or applicable error logs for details."

Please help me ..... Because i didnt take any backup of my database.
