I'm having a very strange problem. I'm hearing a "choooooooooo kkkrrr" sound (Its not like the normal sound speakers make when powered on) all the time. When there is more Hard Disk r/w activity the sound increases and as HDD r/w activity slows down so the sound.

I have two other OS installed on my system. I have tested, it only happens when I'm on Windows 7. I have no clue what the hell is happening !? Any help would be greatly appreciated.

Here's the sample of noise:

attach an audio file if you can. – Moab Nov 11 '12 at 15:48
I would suspect interference your sound card picks up. Is this a Laptop? – TheUser1024 Nov 11 '12 at 16:02
Is this sound coming directly from the chassis, or from the speakers? If it's coming from the chassis, it may be from the HDD itself. Why when only using Windows? Because, some application in the Windows installation may be trying to access a file on a bad sector, leading to a sound from the HDD making several attempts to read that very sector. – TFM Nov 11 '12 at 16:19
There's a burst of noise at the end of that MP3 that might be honest file corruption, or worse (an exploit for some player that's not Google Chrome?) Also, Ziddu is very spammy, but then so is every file sharing site. – Hugh Allen Nov 18 '12 at 22:49
have you checked to make sure that your microphone isn't picking up noise from the system? Check all your recording devices in sound manager. Disable all of them and see if it still happens. – Thraka Nov 21 '12 at 22:12

  1. Detach your faulty headset (if any).
  2. Re-install/(Update) Realtek audio driver (if you were using it). ----------Thats all. My problem is gone now.

I suspect the problem is caused by corrupt audio driver. – Curious Apprentice Dec 4 '12 at 4:27

Backup all important data from your PC then open command prompt and type below command.

Chkdsk c: /f

Note:-C: is a drive letter and /f for fix errors, kindly run this command on all partitions one by one.

That’s a pretty generic answer and only barely relevant. Did you intend it as a diagnostic step? If so, you have enough rep to have posted it as the comment it is instead of as an answer. Either way, you should have specified the /r switch to chkdsk instead. – Synetech Nov 24 '12 at 1:27
I have done that, but the problem persists. – Curious Apprentice Nov 25 '12 at 6:39
