my SQL server 2008 was running fine. About an hour ago, it suddenly stopped - the MSSQLSERVER service had stopped I right clicked, clicked start, and it said the service had started, and stopped

I looked in the event log and saw these two errors:

17207 : udopen: Operating system error 3(error not found) during the creation/opening of physical device C:\Program Files\Microsoft SQL Server\MSSQL\data\model.mdf.

17204 : FCB::Open failed: Could not open device C:\Program Files\Microsoft SQL Server\MSSQL\data\model.mdf for virtual device number (VDN) 1.

The model.mdf db has NEVER been in that location - i specified drive F: to use for data / log during install.

I checked the SQL Configuration Manager, to try and set startup params, but SQL Server is not listed as one of the services.....

EDIT:

I've now moved the db to where it was looking for: C:\Program Files\Microsoft SQL Server\MSSQL\data\ directory.

Now if I start the service, it still does not work - i get this error message in the log: Could not find row in sysindexes for database ID 3, object ID 1, index ID 1. Run DBCC CHECKTABLE on sysindexes.

Interestingly, i checked the error log - around the time users reported problems, there is this:
