Guest Melissa Posted August 24, 2008 Posted August 24, 2008 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!!
Guest db.·.. > Posted August 24, 2008 Posted August 24, 2008 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. -- db·´¯`·...¸><)))º> "Melissa" <Melissa@discussions.microsoft.com> wrote in message news:04881C69-A0FC-4018-8197-F57A1F3AD680@microsoft.com... > every time I boot up my computer this background radio noise plays and I > cannot get rid of it.

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. http://www.radioshack.com/product/index.jsp?productId=2103222 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. http://www.uska.ch/emv/fr/snap_fs.htm Paul
