I have downloaded Microsoft SQL Server Management Studio 2014 Express. I have set it up and I now need to connect to the server. I think my server name has something to do with my computer name but its not working. How do I get in?
Assuming you installed SQL Server, and not just SSMS please read this:

In all likelihood it was setup with the default instance name of \SQLExpress. So to connect, you would enter machinename\SQLExpress.
Ex: Office-PC1\SQLExpress
If you specify MSSQLServer for the instance name, a default instance will be created. For SQL Server Express, if you specify SQLExpress for the instance name, a default instance will be created.
NB: If you open the "Server Name" drop down in the SSMS "Connect To Server" window, there is a "Browse for more..." option which should help you find your installed server.
