Interesting noise coming from the computer??

I just built a new computer system. All the hardware finally came today :D!! I installed all the hardware then the operating system without any issues. It's been AWESOME so far, but I noticed one little thing!!! It's very quiet system.. So I was sitting there listening to it while I was downloading some stuff from the internet, and all i could hear was the CPU or something working, and its the only noise too!!!

The pc is dead silent then as soon as I start opening a program, surfing on the net, or downloading something is when it makes that weird sound??? It's not a fan, and it doesn't sound bad it's just I weird....! The HardDrive has a slight vibration right (when you hear the noise).. Is this bad or is that just how HD's are.. If it is the HD is there a way to dampen the sound?

  1. Hard drive.

    And what are the specs? Hopefully you have some fans spinning.
  2. ok...!! I moved the hard-drive and stuck it on the bottom of the case on top of 2 - 1sq inch foam strips i cut.... WORKS great... no noise at all.... its temps are the same!! now i have to stick my ear up to a vent on the case to make sure the fans are still on.. :)


    Loving it..!!

    Some cases resonate hard drive noise bad. Oddly enough a quiet case like the Antec Sonata has that very problem

    You should check out hard drive suspension as well. its quiet too.

    Enjoy you quieter system.
  4. Yes, and think about replacing the PSU soon. Get a quality one from Seasonic or Corsair or Antec, or even OCZ. Never trust your equipment and stability to a Rosewill.
