I think it might be the excessive voltage/power being dumped on the chasis by the PC's power supply since it's not grounded and entering the HDMI cable connectors/plugs.
Not "excessive voltage/power" but other noise sources inside the
computer finding their way to the chassis ground, being carried along by
the shield of the HDMI cable, and finding their way to your HDMI
equipment through a similar path to how the noise got there in the first
place. This is a manufacturing/design fault.
It's what, in audio, we call The Pin 1 Problem, named for Pin 1 of an
XLR connector being for the signal ground, which, often is "almost"
common with the cable shield.
