SQL Server Management Studio problem with connect - sql-server

I've got problem with connecting SQL Server by SQL Server Management Studio. I installed the latest version. I want to connect by windows authentication. I tried server name like:
computer_name\SQLEXPRESS
localhost\SQLEXPRESS
127.0.0.1\SQLEXPRESS
But it still doesn't work. I'll be glad for any help with this.
error message:
A network-related or instance-specific error occurred while
establishing a connection to SQL Server. The server was not found or
was not accessible. Verify that the instance name is correct and that
SQL Server is configured to allow remote connections. (provider: SQL
Network Interfaces, error: 26 - Error Locating Server/Instance
Specified) (Microsoft SQL Server, Error: -1)
