My Powered PC speakers get louder/softer on their own!!??!!

I just purchased a powered set of PC speakers and plugged them into the green outlet and even though I have my PC and speaker volume set at a particular level, the music coming out of the speakers seems to become louder/softer almost randomly.

What gives?

Could be a problem with the speakers or even the sound card. Yes I know you just bought the speakers but I have seen computer systems DOA, I guess that is what the warranty is for. Try another known setup of speakers to see if the same thing happens.

Can you test the speakers with another audio source (mp3 player, headphone output of your stereo, etc), and see if the problem persists?

Here are the answers to your questions:
1.  The O/S I'm using is Windows 7.
2.  I'm watching a YOUTUBE concert.
3.  The problem is intermittent.  
4.  When I plug my speaker cable into my regular TV, sometimes this happens too.

I think item 4 proves your speakers are not functioning properly. You should return them.
i agree; it looks like you have a problem in the speakers - warranty replacement is what you need
