Thank you all for posting suggestions.
But I am still in the same position where I was. I’ve tried many time with fresh installation with new database name and new copy of WordPress latest version from http://wordpress.org/download/ and also replaced “localhost” to “127.0.0.1” in wp-config.php file too. Even I’ve uninstalled xampp and installed again.
What I found is that after installation no data is appended in the tables of whole database and this is why I can not do anything like I can not log into the dashboard and no post is displaying.
