Open your theme.php and place $name inside your globals look for the following code:

blocks(left);

replace with

    /* Don't display it. */

    blocks(left);
    }

You can do the following for other modules.Note: Place $name in the global part of your theme :

if ($name=='Forums') {
    /* Don't display it. */
    }
    else
    if ($name=='Members_List') {
    /* Don't display it. */
    }
    else
          if ($name=='My_eGallery') {
    /* Don't display it. */
    }
       else
          if ($name=='Private_Messages') {
    /* Don't display it. */
    }
    else {
    blocks(left);
    }
