Personally, I never found ferrites on the mouse/keyboard cable to make any difference.  Although your experiences may be different.

I mean, you could completely sever the electrical connection between your PC and mouse/keyboard by getting a fiber optic USB extender.  Expensive, and would require an extra wall wart to power the USB on the mouse/keyboard end.  I tried this once, but didn't like it as a solution.

Again, my solution was to use old PS/2 keyboards & mice, with the mice having a roller ball instead of an LED.  And having a PC that doesn't dump a lot of noise onto the PS/2 connectors is good also.  :-)  Or having a non-noisy USB to PS/2 adapter works too.
