Thanks.
Most likely (usually) this is noise from the motherboard and other
system internals, so a hardware design fault. Although manufacturers
might disagree about what is an acceptable level of noise. If that's
true then your best bet would be to get a USB microphone, which
separates the mic electronics from the noisy internals of the computer.
