CAnnot Open SEPM

Hello - for the past few days i have not been able to open my SEPM.  Im running ver 12 with a SQL database.  The services keep stopping. 

I log on to the server - try to open the SEPM and get the message that the server is not available contact your administrator.  I go check the services and all the services are started except the SEPM.  I start the service.  I waited a half a hour and tried to log back onto the server.  Got the same message.  Xhecked the servces again and the SEPM service has stopped.  I loked at the event viewer and there is a error that states "the java virtual machine has exited with a error code -1, the services are stopped".

How do i fix this problem?  Any help would be appreciated.

thanks
