Whistling noise from MB especially while scrolling
Hi!
Below is my basic configuration. It's a new machine: Window7-64 bit w/support for 32 bit apps. Logitech G5 Laser mouse (with tail) Intel 860 CPU GA-P55A-UD4P MB GV-NT98TSL Graphics (Geforce 9800GT, Silent-Cell, 1-GB) Corsair 750HX PSU Intel X25M SSD The machine is usually quiet until it plays audio (even if mute is on), say with Windows Media Center. Then there will often be some high-end organ like/whistling sounds in the background. Again, this is not audio, these sounds are coming out of the case. The offending noises can most easily demonstrated by scroll images, say at Google.com, and are also created while using the mouse with the Google SketchUp Program. I think the problem may be a little less offensive since I plugged my mouse into the front of the case instead of directly into the MB (back of the case), I'm not sure. Since the noises basically start following the use of audio, I thought that it might be an audio driver. I am using Realtek High Definition audio drivers that are dated 12/8/2009. According to Windows these drivers are up to date. I have tried several BIOS changes (disabling C1E, for instance), but am not having much success. I thought of buying a PCI USB card for my mouse, as, according to the schematic in the manual, the USB on the MB uses the PCI Express bus. But, if the GPU is causing the noises then this won't help. I'm running out of ideas...thank you for your thoughts or suggestions! Bill BTW, when something like this used to happen with an older system I had, I used to reduce the "recording volume" (or something along those lines). Audio adjustment seems to work different in Windows7. I am not using the "line in" or "record" inputs on the MB. |

Whistling noise from MB especially while scrolling
Here is some further info, I determined since I sent the following message: From Device Manager, I see -- USB controller, no driver found -- Marvell 91xx ATA device, no driver found Windows can't find drivers for the "devices" above (not sure exactly what they correspond to). I just have a USB, mouse, keyboard and printer--and they seem to work. The "whistling problem" seems to come and go... Bill wrote: Hi! Below is my basic configuration.

When you install, after Windows is finished installing, you can look at your motherboard CD for drivers. Adding chipset drivers, should allow resources in the chipset to be recognized. That might include, for example, announcing the USB ports to the system in such a way, that the built-in Windows USB drivers pick them up. The Marvell thing is probably on the motherboard CD as well. ******* Whistling could come from: 1) Vcore regulator coils. 2) GPU regulator circuits/coils. 3) Power supply coils. Any switching power converter might be a potential culprit. While placing silicon rubber on the coils, might be an attempt at a solution, there is no guarantee that would be sufficient to damp it out completely. I've heard similar sounds here, only it will be the "hissing" type, where there isn't a definite tone to the sound. And that can come and go, be sensitive to displaying images on the screen, and so on. In terms of directionality, I've had poor luck with picking out the exact item responsible for the sound. That to me, is the main problem, the uncertainty about which source it might be. In reading the reviews on Newegg for your power supply, a few people mentioned the purchase of that supply, was to improve the noise that was coming from a previous purchase. Something about their previous supply, causing the video card to make noise. Paul |

You were right! The USB device was for USB 3.0 (which I didn't think I needed yet) and the Marvell was for a driver I started to install and didn't finish. I finished installing it and the Device Manager is happy. ******* Whistling could come from: 1) Vcore regulator coils. 2) GPU regulator circuits/coils. 3) Power supply coils.

Something about their previous supply, causing the video card to make noise. I chose the PSU I did because of it's quality and especially because of "low noise" performance. I don't think the PSU is making the noise, but I can't say for sure yet. The problem seems to correspond more to the GPU. Thank you for your help! Paul |

Do you think that putting the mouse on a USB connection powered by a PCI slot might take care of the "whistling"? According to the schematic diagram in the manual, the PCI bus is separate from the PCIe Bus. I'll get someone to create the noise for me, and I'll put my head in the case and track down where it is coming from! Maybe I can literally put my finger on it! Thanks, Bill |

A PCI USB2 card won't be that expensive, even if bought locally. The reason I say that, is eventually, the +5V or +5VSB used as a source of power, is coming from the same place. Do you have another video card you could test with ? If the noise is coming from video, swapping cards might make a difference. I have a PCI video card, that I keep for emergencies (like debugging dead video), and maybe if you have something like that, you can test the theory that the video card is doing it. A PCI video card would do two things - it draws less power than a gamer card, it also has a different converter design (mine has a cheesy single phase converter). Paul |

There is a Gigabyte 7600GT (silent-cell) GPU in the computer I recently gave to my wife. Maybe she'll let me borrow it while she's asleep! : ) I'll report what I find after I do more analysis. Thanks for your help! Bill |

FWIW, I swapped my GPU with another fanless Gigabyte GPU (7600GT) I own, and the problem persists. It's really like a roller-coaster as far as the intensity or the noises created. It occurs whenever the computer has to do something that "challenges it" at all (such as start-up), scrolling, etc. I expect you are correct about the capacitors on the MB being the culprit. Thanks.

Thanks for your help! Bill Bill, stick it in your ear ol' chap! 'Tis one of the few times in polite society you can offer that exhortation in a friendly manner Get a long shafted screwdriver, stick the handle in your ear and probe various spots to track down the sound source. 1st wrap the shaft with electrical tape for safety. It often (not always) works pretty well in localizing a sound. You must have a teeny head or a whale of a case to execute your plan of putting your head inside the case. If you probe on an inductor or other mobo components, it would be a good idea to put a small piece of tape on the blade to avoid creating novel circuits in case the screwdriver slips. ---- Pete Gebel pfgebel(deletethis)@crisperiodcom Have the best day possible - all things considered |

I was wondering how to track the source better! I can't shrink my head or enlarge my case, but I have a pretty long screwdriver.
