Why do we keep talking about scripts. There is no need for one. Go to

Control-Panel -> Administrative tools -> Services...

Find the "SQL Server *" services. the one's with (MSSQLSERVER) or (SQLEXPRESS) or whatever your instance name is, are the ones specific to your instance.

Generally the Browser is disabled.

You can also use the SSMS and right click on your server. Using SQL Server Configuration Manager you can configure the services to start automatically.

Start -> Programs -> Microsoft SQL Server 2005 -> Configuration Tools -> SQL Server Configuration Manager

Something else worth looking at:

Start -> Programs -> Microsoft SQL Server 2005 -> Configuration Tools -> SQL Server Surface Area Configuration

I hate to state the obvious some times, but RTFM.
