I'm running windows vista, and i believe it might of done it on xp along time ago, not sure. But anyways, every now and then, i used to hear a "cracking of a whip" sound like every minute or two, and it's very annoying. Then recently in the last week, the whipping sound is gone, but now it's been replaced with about a 1 second porn theme kind of sound. I believe the culprit to be ffdshow, but i cannot find out how to turn the noise off, or even if it is ffdshow for sure. Any help at all would be great, thanks in advanced.

Sounds like you have a Virus and/or spyware. You'll need to clean it.

yeah i've considered that, but for some reason i think it's just ffdshow mainly for the reason when the sound happens, ffdshow's tray icon appears for that brief moment, then disappear. I've disabled the tray icon in ffdshow since, and now the icon doesn't show, but the sound still plays.

OK - Go into the control panel, add/remove programs, and uninstall ffdshow. If the sound stops, you've definitively found and solved the problem. But if you need specific advice regarding ffdshow, I'm not going to be able to help you much as I've not used it. You'd probably be better off on a forum with users of that program.

I checked the site for this: http://sourceforge.net/projects/ffdshow and I don't see any reference to Vista. So one thing you might try before removing it: Right click the program icon, and select 'Properties' at the bottom of the drop down. On the menu that pops up, choose 'Compatibility'. Check the box to activate compatibility mode for the program and choose which mode (XP..) you would like that program to run in. See does that solve your issue.

alright thanks alot for your time, i'll go ahead and give it a shot and see what happens.

So were you able to find out why window has that whipping sound and what triggers it? I have that same problem too.

I'm running xp, and have exactly the same problem, ie weird random whip noise. Haven't been able to find any info on it anywhere, but am a little worried as have only yesterday formatted and reinstalled and already, after only a few hrs use, IE is crawling. Is it possible that one of the files I backed up was infected?

Am beginning to suspect it may have sth to do with Daemon tools as that's one of the few programs currently installed (Or maybe DC++ ?).

If anyone knows anyth about this rather odd problem, please post back... it's driving me mad.
