Im making this guide, because support asked me too so here it goes...

This guide gets rid of those annoying sounds you may get when using loot pick up ( Ctrl + A ) or
when sending chats, its a noise from windows here are the screen shots on how to do it

Ill assume you know how to get to control panel if not...you can get to it from the start menu


After double clicking the Sounds and Audio Devices then you should get this screen


Here you can turn off all the window sounds from under the sounds scheme.
Change it from Windows Default to No Sounds and then hit OK


That will get rid of those annoying sounds...Enjoy !!!
