Strange noise...coming from INSIDE my PC?

[feo]

OK everytime i'm in photoshop or microsoft word and I do any type of scrolling theres a strange noise that sounds like it's coming from inside my pc..maybe from the pc speaker? anyone have any idea why? it's been like this since i had my machine and it's getting irritating now.

could you say the sound in text?

 

[feo]

The best way to describe it would be a kinda like a 'crackle'...

 

[Flippit]

Open up your case, find a little speaker that's attached to the chassis. This is your PC speaker. Follow its wires to the motherboard and unplug it. Start up and see if the sound is gone.

If not, plug it back in, turn off again, and unplug any extra fans, one at a time, and boot back up, check for noise. Don't unplug CPU/GFX fans

If that doesn't work, get back to us.

Will do...can I unplug the PC speaker wire from the mobo while the computer is still on?

I think unplugging it while the pc is on is a bit dof I say. lol

Don't touch your motherboard, you'll bust it. Hold on to some stainless steel taps before unplugging the speaker to remove all static electricity, then you can unplug ut, and don't walk around in your socks when discharging. rofl.

Are you sure theres no weird animals/monsters in there?

I have dealt with 1 or 2 such problems.

If theres something strange in ur PC's hood.....who you gonna call? (DRUMROLL!!!)

if the noise is very very very faint, then it's most likely capacitors making that noise, from my experience. If the noise is a bit louder, then ingnore the rest of this post.

do you have a tft screen? if so, it is more likely to be the electrolytic capacitors in the invertor making the noise. Replacing them with tantalum should solve the problem. Yes, I know, not exactly a DIY job.

If you dont have a tft screen then probably it is the mobo/gfx card...same thing...electrolytics vs tantalum.

BTW, the noise I am talking about is very very faint, much easier to hear on notebooks (at 2a.m. in the morning in the bushveld), but depending on how quiet your fans in your desktop are then you may be hearing them also. Just learn to live with it.

What can also happen with some brands of CD rom drives is with the little link that gives you digital playback it messes with your sound and you often hear phantom sounds such as typing, hard drive sounds and all sorts of nifty electronic pulses.

I know this crackling/whining noise, have experienced it on some of the computers I have built for myself, it can be irritating because you dont know why its there. Normally happens to me when you scroll the mouse. I think there somehow is signal interference and that interference gets carried to the sound circuits and then its audible. Happened with onboard sound and and Sound Blaster cards, my current PC is luckily quiet.

If all else fails Werner, try unplugging the little cord that goes from the back of your CD drive to the soundcard. Works beautifully every time for me.

To me sounds like loose speaker wires with the vibration of the machine...

Try this:

* disable Digital Playback in Windows Media Player
* ensure the sound card has no conflicts in Device Manager
* move the sound card to the last slot inside the computer
* replace the sound card or video card

Enable DMA (Direct Memory Access) mode for the sound card. In a nutshell, DMA allows soundcard data to be processed efficiently and reduces sound latency (stuttering).

I ripped a stick of RAM out of a 486 while it was on . Computer froze and had to reboot it, RAM seemed to still work after that, but I am guessin it might have some errors on it now. lol

 

[werner]

hey they dont call it plug and play for nothing.
ripped sound cards out of powered on pc's before and replaced with others..."windows has found new hardware" lol. A little speaker cable isnt going ot harm

@Antithesis: not my topic mate, but most cdroms dont need the little cable anymore either, so I cant rip mine out as it doesnt have one. Digital audio over the ide bus. ta.

 

[AntiThesis]

Aah well was worth a try Werner I know that was the problem with quite a few clients before it became all about the IDE bus.

you can mute your pc speaker with windows sound control, er... instead of opening your case.

Sometimes if you hear humming you can mute MIDI play back (especially on crappy sound cards)

also line-in should be muted to prevent any phantom noise.

But could also be something physical like wires etc... work outside-in not inside-out as over zelous wannabe techies often do.

What about Static...Faulty speaker or any electronic devices such as a radio,hair drier,near PC...Just ideas
