Cursor movement making a noise

[Josh Weston]

Just wondering if anyone else experiences this;

When I move my mouse, and therefore the cursor on the screen, I can hear a noise coming from my monitor. A high pitched little drone, which stops as soon as the cursor does. I remember an old monitor of mine used to do the same thing on my old, old, old PC - it really can get distracting.

As much as I don't wish to inflict this upon anyone else, I hope that I am not alone!

Regards,

Josh.

Have you tried another mouse?

I have had this prob, it turned out to be the wire from my mouse was touching my spdif cable and was picking up interference from it. Check the cables at the back of your PC because one of them could be doing the same.

[sup]I have noticed this at times. I would agree with sieb that it could be physical interference with cables but Im quite sure my hardware is isolated adequtely. I'm very interested in regard to peoples exlanations of this phenomenon[/sup]

I'm currently away from my PC, but I'll certainly check my cables etc. and see if it makes any difference.

And as for trying another mouse - I don't actually have another mouse that would work with this PC!

I've realised that when I plug my headset, the noise starts coming out of my headset! Very strange indeed. It also seems to be more prominent when my cursor is going over darker areas of the screen. The incessant buzzing noise is slowly driving me insane

I'll make sure to post back tomorrow after I change some wires around, and maybe reinstall some audio drivers.

Hey Josh not sure if you have a Corsair AX850 but I get that sometimes to. I've heard that some AX850 have a electronic wine to them that the other models (750,650 etc) don't have. Sometimes I don't hear anything at all, sometimes it's just a wine you can hear coming from the power supply if you put your ear up to it (with your ear up to the power supply you can hear the tone change a bit also, and sometimes it is related to the mouse movements (not sure how though) but the pitch of it changes according to how I move the mouse. I am also not 100% sure that the mouse movement is coming from the power supply, that could possibly be something else, but with the other whine noise I did put my ear right up to the exhaust of the power supply and I can tell it is coming from there, I also googled it and read that that is a issue for some AX850s.

 

[Josh Weston]

Yup, AX850.
Well, that's an odd one.

Ah yes, that's what I was guessing. I grabbed a 850 to cover myself incase I ever wanted to do dual graphics cards--it is a bit annoying though, I may have picked a AX750 if I had of known about that.

I do also think that i'm hearing interference from the onboard audio. If I plug my headphones into my PC, the 'cursor noise' ceases to be audible until i put the headphones on.

Do you also find that you're hearing different tones etc. if your mouse is hovering over different things? For instance, you'll get a different noise from going around your desktop than a program window. Or the colour black over the colour white?
I'm finding some pretty strange correlations here!

Yes the audio may have something to do with it, not really sure. I don't notice the mouse thing all the time, I will have to look more into that (Planning on getting a Xonar essence STX soon anyway for better output quality during games etx. I guess you could try disabling the onboard online in the bios if you can do that? I imagine you can. Also try putting your ear up to the back of the power supply and moving your mouse around see if you can hear the changes directly from there.

This video shows that type of thing--different noises from the back during different things on screen http://youtu.be/Kjq3K7e7s1c

I don't know if you ever watched Toms video on the Radeon 6990 cards but it reminds me a bit of the whining noise those make. http://youtu.be/nKWbwjiR7h8

I dont know where the water cooled version went but you could hear it more in that video

 

[Josh Weston]

Hmm, well - I just put my ear up against my PSU whilst moving the mouse and heard nothing from the PSU.
I did however hear stuff coming from the speakers, and it's very dependant on what the cursor is over. Looks like I need to buy myself a soundcard, and see if it's simply because the audio circuitry is protected from the rest of the electronics on the motherboard.

 

[jamesriley94]

If you mute or disable the onboard soundcard, whether in windows or BIOS, what happens?

 

[Etlar]

Soundcard is funny, one of my friend have the same problem whit his Asus Xonar Phoebus. And he just RMA it and got a new one, there was a fail in the power linie on the card.

So try out the onboard first and see if that helps, or get the driver from the onboard out of the system.
