Hi,
Can you make sure that your localhost is working by typing http://localhost/ in your browser after running XAMPP.

Did you use manual installation? If yes then use these:

/** The name of the database for WordPress */
define('DB_NAME', 'dbname');

/** MySQL database username */
define('DB_USER', 'root');

/** MySQL database password */
define('DB_PASSWORD', '');

/** MySQL hostname */
define('DB_HOST', 'localhost');

Also check your table prefix:

$table_prefix  = 'wp_';
