First , login as an admin user-  then try executing this script.

USE master;

EXECUTE sp_addsrvrolemember @loginame = N'MyWindowsDomain\MyUserName', @rolename = N'dbcreator';

If this doesn’t do it, find this LOGIN under the SECURITY\Logins tab (in Management Studio).  Right Click ‘Properties’. See Server Roles – and check SYSADMIN. That should give you all the roles of a sysadmin.
