This is not an isolated incident. The "badBIOS" incident reported by Dragos Ruiu a few years ago ([1]) had many of the same characteristics as what you are reporting:
• Vague symptoms, affecting all computers (and, often, even non-computer devices) owned by the individual
• Inability to isolate the agent involved
• Belief that widely publicized exploits or discoveries are involved, often in the absence of any evidence (e.g, DirtyCOW here, ultrasonic networking in Dragos' case)
Please seek psychiatric help.
