"BONG"

-Edited to make more precise-

So Here's the process in which the "Bong" sound occurs.
-I double click my cracked minecraft client.
-I press run
-"BONG" Then I start raging.

I would love if someone could figure out this problem or what is leading to this.
Please & Thank you for your assistance.

It "Bong"'s and dies my friend..

This is really stressful considering I am making a Bukkit server..
