Buzzing from my Yamaha monitors

Before I try to invest in better cables, i was wanting talk about an issue i'm having.  I have some Yamaha HS5 monitors.  They are right beside my monitors. Not something I can really help too much given my operating area.
 
I have noticed that when monitor is refreshing something like a web page, I get an annoying buzz from my monitor.  If I'm not doing anything on my computer, they are quiet as you would expect and want. I have everything plugged into a nice power conditioner/power strip.
 
At first I thought it could be some kind of interference between my computer, through the USB cable into my Roland Octa-Capture. However, if I turn my Octa-Capture off, I still hear that buzzing sound.  So, I'm wondering if anyone has ever had this problem and if so, did you find upgrading your XLR cables for the audio monitors, and the perhaps updating the HDMI cable for the computer screen/monitor removed that annoying buzz?
 
Thanks for any help.

I have noise in one of my Yamaha monitor speakers.  The other one is totally quiet.  Noise doesn't change with the volume on my sound card.  I've had a hard time fixing this issue.

What happens if you move the monitors away from your screens ?
 
I presume your monitors are active and can therefore amplify any stray signals picked up from nearby.
 
It may be a question of inadequate shielding of the electronics in either the screens, monitors or both.
 

 
I get a whine from my Dell monitor/screen when it's adjusted to certain settings.
 

This is a very common problem, and basic trouble-shooting, as described above, is the way to go.
 
Some additional ideas:
1) is it a hum or a whine? A hum suggests a 60 Hz problem, a whine suggests something a tad higher in the spectrum. Hum is magnetically coupled, whine is electrically coupled. Shields do nothing to reduce magnetic coupling, but a good twisted pair does. Shields do a lot to reduce RF interference. So you have to identify the problem.
 
2) There is a lot of chatter about ground loops. For the most part you need to forget about ground loops, they are not the problem, and in fact they make life safer. Instead think in terms of victim and aggressor. Once you have determined if the interference is power line or RF you can start looking for victims (the loudspeakers) and aggressors (maybe the monitors, maybe other noise impressed on either the audio or power lines.)
 
3) When these loudspeakers were originally released I believe they suffered from the dreaded "Pin 1" problem - that is, the shield was connected to the inside of the cabinet. I also believe that Yamaha resolved the problem. So depending on how old your loudspeakers are you may want to look into "Pin 1" problems.
 
That, and Bit's description above ought to get you started. Come back with more info and we'll figure this out!
 

 
Sounds like a cable.
 

I traced the noise in my speaker to a network switch.  Moved the switch under the desk and the noise is now gone.

Regardless of where the buzzing was coming from, you should use good balanced connection cables from your interface to your mons.

I just solved similar problem by using XLS balanced cables. If your interface does not have XLR outputs, use XLR to TRS extension.
