    So my computer regularly has this annoying vibration sound, like a mosquito, and I was wondering if anyone has any suggestions on how to stop it.

    When I press a finger against the side of the case the buzzing goes away, when I remove the finger the buzzing sound is back, so I just take off the side of the case and that takes the noise away, but after about 10 minutes the sound is back again. If I put a light weight on top of the case (a backpack) the noise will again go away but will come back after 10 minutes.

    Any ideas or suggestions to make it go away permanently?

    Thanks

    decoupling moving parts and dynamat on the inside of the case. i would go for decoupling first.

    figure out what part(s) are causing the case to vibrate. for fans, rubber screws are great. for hard drives, either mount in a 5 1/4 bay, or get a new, quiet hard drive. also, some cases are just cursed with loudness.

    Locate the exact source of the noise, determine if it is electrical or mechanical noise, apply the appropriate solution for each.

    Butyl rubber mass dampening - you can get sheets of it at McMaster-Carr with adhesive backs, or you can buy stuff like Dynamat, or you can get the rubber they use in cars from a car shop. Another option is to get a composite sound dampening foam made for PCs, like Acoustipack, which will both dampen vibrations and reduce other noise.

    Don't get sheets of butyl thicker than about 1/8"... it's VERY dense, and if you used 1/4" of it on the entire interior of your case you'd probably have to have someone help you move your case two feet.
