I have an ATI VGA Wonder+ (the 1024 card) with 512k and a mouse plugged into a no name 386-33 (Hawk motherboard) and connected to a Loop multiscan monitor. There is a whistling sound emanating from the case. Ordinarily with the other sounds coming from the power supply and diskdrive (maxtor-200), I would ignore this sound as just normal machinery noise. However, I have found that the frequency of this sound changes as the screen changes, and even as the mouse is moved from one part of the screen into another. Is this normal? Or, do I have something configured incorrectly? Could this sound be caused by using the wrong software driver for a specific program? Or could the whistling sound be coming from some other device? Thanks for any and all help. -hd

When I was running my machine with the top off for awhile, I noticed as the monitor changed frequencies, the hard drive would vibrate differently and make different noises. If I put a touched the frame of the hard drive, the sound would stop. I suggest you take the top off of your machine and track down the sound. If you can stop it by putting pressure on something, then maybe there is something you can do to stop it. Charles
