conditional insert using exists (AGAIN!)

This statement returns an "Incorrect syntax near the keyword WHERE" error, and I don't understand why ...

INSERT INTO atable VALUES (list of column values) WHERE NOT EXISTS
      (SELECT * FROM thesametable WHERE col_1 = 'something' And col_2 = 'somethingelse')

I know it has something to do with EXISTS; I confirmed that by removing the WHERE clause from the SELECT statement.

Or you can do this:

INSERT INTO atable
SELECT (list of column values)
WHERE NOT EXISTS(SELECT * FROM thesametable WHERE col_1 = 'something' And col_2 = 'somethingelse')
