Annoying beeep noise when moving mouse cursor?

Not sure which sub forum to put this in as I don't know what the cause it.

I just noticed recently and I'm pretty sure it wasn't doing it before, but whenever I move my mouse cursor on the screen there is this really faint beeeeeeeep beeeeeeeeeep coming out of my speakers. It also produces the same sound when I disconnect my speakers and use headphones, so I'm thinking it's likely a software problem and not interference in cables or something like that.

Anyone else experienced this and know how to fix it?

Well it makes the same sound through speaker as it does through headphones so I don't think it's EMI. I rearranged my set up recently and have two laptops running together, I'm plugged into some ACS495 Altec Lansing speakers but they are not that near my laptop, nor has their general relative position changed much. My laptop is on a moveable surface and it does it when i place it at various positions. I'm using a logitech USB mouse plugged in via a 4 way splitter, and it still does it when it's plugged directly into the laptop. Although, when I plug it in via the two USB 3.0 ports on the other side it doesn't do it. I'd like to get to the bottom of this and fix the problem with the USB 2.0 port rather than change ports.

I read somewhere it could be a sign of a failing motherboard? Hope not, only had this thing two years and it's a good machine.

I just ran CCleaner, emptied a few caches and blocked KnowHow Cloud and Nikon Chat something to do with the software for new camera probably from running at start up. Also there was yet another windows 7 update! Seems to have been a lot of them lately. Anyway, things are running a bit more smoothly and the annoying beep sound has gone. So no idea what was causing it but thankfully it looks likely to have been a software bug from somewhere. But of tidying up and a defrag and things should be running even faster soon.

Aaaaarrrrrgh it's no stopped it at all, it's still daein it!

Tried turning my speakers off and it still persists, so basically I've just re-arranged my USB ports and it's gone away. Maybe just one of these things I'll never get to the bottom of. Just hope it's not a faulty motherboard.

Some places are suggesting updating the BIOS but I don't really know what that means or how to do it.

So I swapped over the usb cables and now the 2.0 port on the right is my SD card input. I'm now uploading some photos via there and just noticed a faint noise like the noise old computers from 80s made when loading things from tape, the noise the tape made but quieter. I can deal with that,

but would it be suffice to say at this point that perhaps the circuitry around this USB port in particular might be failing?

and if so does this necessarily represent or indicate that there might be further issues with the motherboard, or just the USB port, or is it just a piece of hardware that might die on me one day soon and my computer will otherwise still be fully functional?

Hi STU9000. I'm not an expert by any means, but I would say it's almost definitely something strange with that port, perhaps it's not properly isolated electrically from the other circuits on the board. I would not say it necessarily means there's any impending hardware failure anywhere. I'd still probably avoid using that port to be on the safe side of things. Not a motherboard circuitry expert, but that's my 2 cents. Hopefully somebody else has a more definitive answer.

Well it is near the output and input sockets for the sound so that's probably something to do with it. Sounds like there is some cross coupling going on. probably could be easily fixed with a strip of metal and some glue.

Definitely don't go at your motherboard with a strip of metal and glue, that can only end badly.
