background noise

[Guest Melissa]

every time I boot up my computer this background radio noise plays and I

cannot get rid of it. I have tried looking for it running but cannot find

it. I seems like a radio station but I cannot get it to stop. I cannot

listen to anything else because this will not go away.

HELP!!

Re: background noise

 

what you can try is

to open the task

manager (ctrl alt del).

 

then one by one kill

each process your pc

will allow.

 

perhaps, the noise is

associated to one of them.

 

when you kill the process

explorer.exe, simply go

to the first tab and relaunch

it as a new task.

 

if one of the processes does

eliminate the noise then

you will now have an idea

of what is its cause.

 

if none of the processes

eliminates the sound, then

perhaps there is an active

webpage on the desktop

that is linked to a radio

website

 

"or"

 

maybe you will have to delete the

sound driver and hope to

get an error from whatever

is playing the radio needing

the sound driver.

Try the following tests.

 

When your computer speakers are connected to the green "Lineout" you hear

the radio station ?

 

Computer ----------- amplified_computer_speakers

 

Now, disconnect the speakers, so the amplified speakers are

no longer connected to the computer. Plug in some headphones.

Now, did the radio station disappear ?

 

Computer ----------- headphones

 

If the radio station can no longer be heard, what you're

experiencing is rectification of AM radio station signals

by the input transistors on the amplified speakers. I've had

this happen on my stereo, when an Apple Macintosh is connected

to it. If I connect my PC to the stereo, there is no such

effect. On the Macintosh, the radio station signal appears,

just after selecting "Shutdown" and ending a session. So

the symptoms don't quite match your symptoms, but it is a

similar effect.

 

If you are close to a powerful AM radio station, that could be

where the signal is coming from.

 

Being a form of interference, I don't know if I could guarantee

a solution for you. It might take some experimentation

to fix it - it might even require a different set of

computer speakers, if the issue is with the input stage

of the speakers.

 

Ferrite filters are one solution, but without specs, it is hard

to say what frequency range this device filters. Read the reviews

for the product, to see some successes and failures. If I had to

bet on what was going to provide the most relief from an RF

problem, this is what I'd try.

You could try shielded cables, but I would not hold my breath.

(They might not change anything.)

 

If your computer has TOSLink or SPDIF output on the back, and

the amplified speakers have that kind of input, that would likely

fix it. That is because such a link is digital and immune to

the problems that can affect an audio cable.

 

For the snap-on ferrite filter, if you wind the wire around the

ferrite core multiple times, that makes the filter more

effective. At least, until the opening in the center is

choked with wire. If you trapped five windings of audio wire

inside the ferrite, it makes the ferrite filter five times

more effective. On this French language web page, you can see

some examples of winding the wires so they go around

the ferrite filter multiple times.
