Strange noises

Does anyone know why actions such as scrolling down a webpage or clicking icons etc is making a sound through the speakers? Its as if you can hear the cpu's actions. I tried searching the forums but its a hard one to search for.

Is it sort of a hissing noise? I used to get it a lot on my old PC, no idea why.

Turn the speakers off and see if it still occurs.

I had a friends machine do this, i think eventually we discovered it was some voltage regulators on the board. Plugging in a usb hub fixed it, it was being caused by any usb device drawing power from the usb.
This is not a disguised pimp, but folding also fixed it by putting the cpu under load, which presumably also put the buzzing power circuitry under load and stopped it buzzing.
We changed everything including the psu, harddisks etc and came to the conclusion it must be something on the board.

Its possible that your speakers are amplifying it, on my friends machine it was so loud it didn't need the speakers to amplify it for it to be annoying.

I get this, but only through my crappy Zalman surround-sound headphones, not my Senns or speakers. It happens when I'm moving the cursor around the screen and is so quiet that I can only hear it if there is no other sound whatsoever, but since I only ever use those phones when my Senns run out of battery it's no big deal for me.

Just for info: I'm using an X-Fi out to a Cambridge Audio AV receiver.

It's a little bit more like grinding on mine, although it's pretty hard to describe.

thanks for the replies. This problem is with the pc downstairs with an audigy zs. I have managed to stop the noise by muting "cd audio" in the sound card options.

My dad who put this together always plus those cables in that come with cd drives that connect to sound cards, maybe it is to do with that? I never plug those cables in, do they even do anything.

Try unplugging them. I've yet to work out if they do anything or not, i did think they were for the front headphone port on cd drives but mine don't have a front headphone port but still have a connector for those cables and seem to work the same with or without them.

I have to connect my X-Fi to my TV card using one of those cables to get the TV audio - spent ages trying to get the audio through the TV card software before I realised that the TV card actually had an internal audio socket. I think this is the only time I've used it though

Incidentally I do remember having the weird sound both before and after plugging the cable into the sound card ...
