Disconnect and reconnect?

@XOIIO
I did that and same noise?

hmm, do you have a seperate audio card? Could be failing.

I have an Intel CoreDuo 3.0 Gb, purchased in 2007.
The speakers were purchased then too.
It is a desktop PC

I’d say reinstall your audio drivers, first uninstall them my right clicking on computer and manage, go to device manager, and find them and uninstall, then run windows update and downloading them that way or going to the website of whoever made your pc (dell, hp, etc) and finding the drivers that way.

Thanks I will try and restart my computer now.

It sounds as thought the input wire to your speakers is bad. If you can unplug both ends, try replacing it with one that works somewhere else, and test the wire with another source and/or set of speakers. If you can’t unplug both ends of it, then try another set of speakers (one you’ve seen work on another source) with your computer and see if it works. Once you’ve ruled out everything downstream of your computer’s audio connector, then it’s time to try reinstalling drivers, etc.

My first guess is also a bad wire.

They are not grounded.

Bad connection somewhere. It could be the wires to the speakers or the plug or the jack on the sound card/motherboard that you plug the speakers into. If you have a sound card separate from your motherboard, try pulling that out and re-seating it.

With the bad connection the wiring is acting like an antenna picking up whatever electro-magnetic disturbances are in space around your machine (mostly 50/60-hz powerline radiation) The amplifier in the speakers doesn’t know that little signal on the wire is not your music.

The restless ghost of Steve Jobs is community to you. If you can filter the white noise you will hear him clearly say, “stop looking at German Midget Pornnnnn!”

Looks like I have to take the thing apart to searh inside in case the sound card “fell” or got loose?

If you’re not used to doing that, as you pull cables off the back and as you take the case off, take pictures of things that you might not be sure how you’ll remember how to put back together.
When you get inside, be sure to touch the case to dissipate any static from your hands, before you handle circuitry like a sound card.

One thing at a time. Have you tested enough to satisfy yourself that the cables and the speakers are not at fault? Until you have done that, it’s too early to open the case.

It’s unlikely that the sound card has come loose or that its connection has failed due to mechanical stress, because expansion cards are normally screwed into the case to prevent just that. Also the connectors are usually braced by the slot cover. It can happen, but problems external to the case are much more likely, and should be eliminated before proceeding.

I am sure there must be some problem with your speakers wiring. Get it checked.

Will purchase new speakers in the meantime. Thnaks.
Not too comfortable opening the case.
But will do that as a last resort since I don’t know what I am doing in this regards.

Heck, the sound circuits might be on the motherboard, that is pretty common, and in that case there is no “sound card” anyway.

Cord might be in wrong hole.
