Pagination doesn't work

Hi There,

I’ve tried to add a pagination to my query but can’t make it work.
When I click to get to my second page of posts I just get same list of post as the first page. Nothing change.

I can’t see from where is the issu. I have $paged and a link at the bottom to get the second page.
If I move $paged before $wp_query = new WP_Query(); I don’t get any result??

Thanks for helping me.

<?php
//Create a new filtering function that will add our where clause to the query
function filter_where($where = '') {
  //posts in the last 30 days
  $where .= " AND post_date < '" . date('Y-m-d') . "'";
  return $where;
}
// Register the filtering function
add_filter('posts_where', 'filter_where');
// Perform the query, the filter will be applied automatically
$temp = $wp_query;
$wp_query= null;

$wp_query = new WP_Query();

$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
query_posts('category_name=events&posts_per_page=10&order=DSC&orderby=date&post_date='.date('Y-m-d', strtotime('-300 days')).'&paged='.$paged.'');?>
            <?php while (have_posts()) : the_post(); ?>
                   <div id="post-<?php the_ID(); ?>" <?php post_class(); ?>>

					<?php
                    $custom_fields = get_post_custom();
                    $my_custom_field = $custom_fields['eventdate'];
                    foreach ( $my_custom_field as $key => $value )
						{
						echo "<div class='eventdate'><p>$value</p></div>";
						}

                    ?>

            	<h2 class="entry-title"><?php the_title(); ?></h2>
                <div class="entry-content">
                <?php the_post_thumbnail('large'); ?>
                <?php the_content(); ?>
                </div><!-- .entry-content -->

            </div><!-- #post-## -->
        	<?php endwhile; ?>

		<div class="pagination-events">
        	<?php previous_posts_link('Upcoming Events'); ?><?php next_posts_link('Past Events'); ?>

        </div>

        <?php wp_reset_query(); ?>
