Can't start SQL services
Go to Command Prompt and Try Start Service With This

NET START MSSQLServer /f /T3608


Then in Command Prompt Login With SQLcMD

SQLCMD -E  -S ServerName


Then run Following Command to move the model log to the F drive.  Make sure the path is correct.

ALTER DATABASE Model MODIFY FILE( NAME = modellog , FILENAME = 'F:Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\modellog.ldf' )
Go


Then stop and re-start your instance.

Repeat with other files if needed.  Except master.  That is a whole different problem.
