Acer Aspire 5672 freezes when volume is too high?

I like to listen to music while I am working on things on my laptop, but the problem is that if I have the volume up a little past halfway my laptop freezes and the music starts skipping, it unfreezes after I press the play/pause button on the media bar (beside the keyboard) and press the volume down button repeatedly until my laptop unfreezes.

I am wondering why exactly its doing this, I have the proper audio drivers installed.

System Specs are:
-1.6GHz Intel Centrino Duo
-2Gb RAM
-WinXP Home Edition
-Windows Media Player 11
-Acer Audio drivers

Does anybody have any clues about whats going on here?
