My Server/Website [URGENT]

I've got this problem were these noob script kiddies are making 2000bots + visit my website cousing httpd to totaly lag like hell

I have looked into this but its not the httpd coursing the problem as I replaced the php with a simple index.php blank

It seems it only lags when it querys the db 1000's of times
Is there a way I can stop the db from trying to process this amount of requests IE making it to stop at 50requests at a time

The server has cpanel/whm installed so if You do give me info on how to fix this, Mysql might be located some where else

If You can help thanks so much
