Is a "buzzing" ecu indicative of imminent ecu death?

Hi all.
Had the regulator/rectifier fail recently on my '99 SRAD, replaced it with a Mosfet one but now there is a distinct buzzing coming from the ECU although the bike appears to be running fine. Anyone else experienced the buzzing and if so what happened after that?
