How to increase volume of a laptop/ PC more than its default

I tried pretty much everything such as increasing system volume and that enabling "loudness equalization" which actually decreased the volume. Anyway figured out that VLC media player gives more volume than the Windows Media Player.

All you have to do is get VLC Media Player from here. (http://www.videolan.org/vlc/)

You will notice that it shows the volume as 200% . But when you keep hitting ctrl + up arrow, it keeps increasing volume. Google search results say it increases the volume upto 400% but i dunno, i dont feel that much, anyway its way louder than the default volume

If its still not loud enough u can try pulling the bar on graphic equalizer it has as its shown in this video below (which is gives u no clue if it increases the volume or not because it has no sounds. pretty dumb but some people like to know where to click)
