The former setup (XP pro SP1) caused the very same problems, but apparently a *new board* and replacing the video card didn't solve this. I was able to drill down the "heart beat" problem to the onboard LAN card: as soon as I disable the device (BIOS or device manager) the beats are gone. The PC is supposed to be used as a DAW (digital audio workstation) for video editing, music recordings, and (serious) 3D graphics (not games) Both speaker sets buzz along with my mouse and any windows actions on the desktop.
Speakers are Tannoy monitors for the front channels, Heco for the rear, a Canton subwoofer, and a 2nd set for audition recordings with a cheap vanilla 5.1 PC desktop set. If I turn up volume to 60-70%+, a crackling sound adds to the "heart beat" in the subwoofer which makes it sound like a turntable reaching the end grooves of a vinyl record (turntable and vinyl records = hardware/media used in the pre-CD area -> ) If I raise the sound volume (and I mean "medium") I can hearĪ) a deep sonic "heart beat" through the subwooferī) some Star Wars Jedi sword fight like "buzzing" sound when moving the mouse or a window is being resized, dragged or scrolls Here are the symptoms which are driving me nuts, and which is the MAIN problem I need to solve:
I'm about to re-install my DAW (see profile) hoping to solve the phenomenon.
