Manage Engine Server desk plus is not starting...

I am using Version 10.0 with Windows 2012 R2 Standard and SQL Server. I suddenly stop working as everything was working fine from the last few months after upgrading.

I have tried to apply some solutions from other searches like

1- Changing config file entry from mssql entry to pgsql or mysql.
2- closing java process from service desk and restart the service
3- restart manage engine VM and starting services again.

Is there any log file I need to share or anyone who can help me in this .
