my step dad has the same problem and i fixed it with no trouble. I clicked the windows button and then went to control panel and searched sound effect (sound should be the only result.) once that window comes up, double click your speakers, and choose enhancements. At the bottom you'll see setting. choose from the drop list. some have echoes. some don't. There you go. just click apply. :)
by the way , he has the same laptop. good luck
