24" monitor and noise

[glockmail]

I recently upgraded to a new LCD 24" wide screen. I had to put in a video card to support it, actually one that I salvaged out of my parts pile, originally bought for my son's game machine. Something odd happens now: When I scroll in certain applications, the computer makes a corresponding noise. Its kind of a faint, high pitched buzz, almost a ring, that comes from the box. It mostly happens in AutoCad when I drag large text blocks but in other apps less pronounced.

Any ideas what it is?

Does the monitor have built-in speakers? If it does, it may have something to do with your cell phone. If you're cell phone is close enough to the monitor for its electronic field to affect the monitor's electronic field, the phone's signal will produce "static" that can be heard through the speakers. Try putting your cell phone up close to the speakers and listen for the noise. If it's the same one you've been hearing, then I've solved the problem.

The monitor does not have speakers. The sound occurs regardless of the phone being on or off, or in the same room. the volume control on my old speakers also has no effect.

The reason why I am curious about this is that I wonder if the video card is strained and starting to malfunction. When I turned on my computer this morning the monitor was switched on, the stoopid windoze music came on, but there was no picture. I tried several manual restarts but did not correct the problem until I switched the monitor off, then on again. Of course, that could be an unrelated problem.

Did you remove the old video card? Does the card you install have audio on the same card? Just a couple thoughts..one more, check 'system information' for conflicts.

The old video "card" remains on the motherboard.

I just checked the Device Manager: there are "No conflicts", and a better driver match could not be found using "update Driver". Also, "The device is working properly."

The card is a NVIDIA GeForce4 MX 440.

Did you disable the onboard card? To me it sounds like a bad card. If your looking for a cheap card go here www.computergeeks.com you can even email one of their techs with this problem and they would probably help you. I usually get all my computer parts from them.

Can you tell if the old card is operating or is it disabled? Can you remove the old card?
