so sloved the problem it was with the database load
($this->ci->load->database();)
no error were showen only thing in log of CI was (Database Driver Class Initialized)
problem was that php 5.5 doesnt come enable , need to enable it.
locate the php.ini (cmd->run c:\php\php.exe --ini for location)
edit the next stuff in file:
extension=php_mysql.dll
extension=php_mysqli.dll
extension_dir = "C:\PHP\ext"
then make sure that in apachee httd.conf u have it ponted to the location of the right php.ini
PHPIniDir "C:\php\PHP.ini"
hopes this help some one in the future :)
