What constitutes "increasingly frequent"?

I've had keyboard that killed a system (wasn't intermittent in my case).
So I'd check the remaining pieces, especially if you've got spares handy.
Power cord included.

Do all of the machines use the same distribution/version OS?  Preferably
something newer than 14 years old?

Intermittents are such a pain!
