It would have helped a lot if you had given useful hardware & software answers in this thread
http://www.legendsworld.net/webroot/phpBB3/viewtopic.php?f=3&t=18111&view=unread#unread. Your CPU cooler has nothing to do with the game, nor does the monitor you are using. Software means which Operating System are you using (and video card driver version), and hardware is what cpu (Intel or AMD & stock clocks or not), how much ram you have, video card, etc. This is not a one way street, we cannot read your mind, i.e; you want help but do not provide useful information from your end.
The answers you are getting are "unserious" because those who want to help have almost nothing to work with. So be more descriptive with the problems you are having.
I know that English is not your first language and that you are not so great at it, but please try your best.
