not able to use mysql server

hi i am using windows vista and installed wamp server, initially i installed wamp and accessed phpmyadmin and while setting a password for the root i did a mistake and could not access phpmyadmin and also renamed some php files so i uninstalled wamp server and re installed now the problem i am facing is when i click on mysql.exe located at D:\wamp\bin\mysql\mysql5.1.36\bin i am getting the following error error 2003 cant connect to Mysql server on localhost 10061 in config.inc.php located at d:\wamp\apps\phpmyadmin3.2.0.1 i have the following $cfg['Servers'][$i]['host'] = 'localhost'; $cfg['Servers'][$i]['port'] = '3306'; $cfg['Servers'][$i]['auth_type'] = 'config'; $cfg['Servers'][$i]['user'] = 'root'; $cfg['Servers'][$i]['password'] = 'root'; $cfg['Servers'][$i]['AllowNoPassword'] = true; along with others. when i type http://localhost i am able to see the welcome screen of wamp and can click on phpinfo but when i click on phpmyadmin it takes a while to load and a blank screen appears also i have stopped all services and restarted all services from the wampserver icon in the system tray, normally the colors change from red to yellow to white, the color is at yellow and does not change to white how do i solve the error error 2003 cant connect to Mysql server on localhost 10061 so that i can use phpmyadmin please advice. thanks.
