PHP Configuration : PDO extension is enabled but not loading - php

Question

I'm using Windows 7, wamp server version 2.2, PHP version 5.2.9. When I try to run my magento websites on a localhost it gives me the following error:
"The PDO extension is required for this adapter but the extension is not loaded"
I have double check that PDO extensions are enabled in the php.ini file.
;extension=php_bz2.dll
extension=php_curl.dll
;extension=php_dba.dll
;extension=php_dbase.dll
;extension=php_exif.dll
;extension=php_fdf.dll

;extension=php_zip.dll
Also the phpinfo loading the right php.ini file. It was working earlier but suddenly start to give the error. I also checked the Apche error log but didn't find any clue.
Please suggest.

First move the extension directory to \Windows\System32\inetsrv{php}\extension
Change the path from php.ini file
I think you have a security problem to loading .dll! Try this and let me know the result.
To find out which php.ini file has been loaded, try the following ( run in commandline and webserver to make sure which edition loading different environment).
Checking the php.ini file path :
<?php
$path = php_ini_loaded_file();
echo 'The loaded file path is :' . $path;
?>
