Does anyone have any on removing vibration from an exteral source

I'll explain, my father in-law is a professional musician. He has large external speakers witch is connected to the PC and his other equipment. Sometimes the music he plays must be very loud, now here is the computer problem. Occasionally he has issues with the Power supply where some connections come slightly loose and cause the PC to not turn on. just a week or so the CPU fan even rattled loose.

So my question is does anyone have any ideas on how to dampen the vibrations to the PC?

If you need more information let me know.

Thanks in advance.

Put your hand on one of the speakers when in use, feel the vibration. That vibration transfers through the air and causes vibration of anything it hits. Not much can be done when the sound is loud but to turn the volume down, move/redirect the speakers or move whatever it's causing the problem with. You can get a simple visualization of the sound waves action by looking at the volume icon in the Notification Area on the computer, gives an idea of how the sound waves spread out over distance. Sound does diminish over distance away from the source but it is not enough in smaller rooms. Rock concerts take advantage of what can be done [which is why I avoid them].
