I know transformers can cause speakers to buzz or distort if the transformers electrical field is large enough.

I'm thinking it may be a frequency your computer is giving off which is affecting your radio. I had a similar problem when my Furness would turn on. While the igniter in the Furness was igniting my speakers would make a humming/buzzing noise then would stop when the ignition was complete.

In this case moving the radio will not work unless you move it on the corner of your street but that’s not to helpful. I'm not to sure how to stop it since my problem went away when I got new speakers.

So to test this try moving the radio closer to the computer if the noise of the radio is greater then this theory is true if not then it probably is to do with something similar to what CookieRevised said.
