SQL Server - Persiste problemas con Servicios Sql 2005

Hola sigo teniendo problemas con los servicios del SQL server 2005 en mi servidor ahora no arranca el servicio de manager de sql ni el servicio de sql server, tengo un Servidor con Windows 2003 Small Bussines, este sistema operativo trae algo de Sql server desktop engine (sharepoint) y Sql server desktop engine (sbsmonitoring) sera por esto que me esta dando problemas???si desintalo estos programas se me soluciona el problema???porque he investigado y me dicen que ese error es debido a que tengo varias instancias de MSSQL en el servidor como soluciono este problema es urgente...
Gracias por sus respuestas...

¿Cuantas instancias tienes en tu servidor instaladas?

Hola tengo una instacia ya creada por el sql server desktop engine...

Exactamente este es el mensaje que de error que me da al tratar de iniciar el servicio de Sql Server 2005: "The request failed or the service did not respond in a time fashion. Consult the event log or the other applicable error logs for the details"

¿Ya revisaste el LOG DE ERRORES?, ¿algun mensaje en este?

Esta es la informacion que arroja mi log de errores
