Inspect your home for signs of carbon monoxide exposure or other gases from cooking appliances or heating systems. Such exposure can lead to symptoms like paranoia or hallucinations. The sensation of being addressed and responding to your voice feels similar to this experience. Do others in your household notice these sounds when you do? Invite a neighbor over to listen and verify. Unless it's actual neighbors deliberately targeting you because they dislike you, consider other possibilities.
A faulty audio cable between speakers and a computer might act like an antenna, picking up radio signals if you're tuned to the right frequency. You might hear static or radio noise, but it's unlikely someone would intentionally broadcast on your frequency. The motherboard only has a beeper, which produces limited sound and can usually be turned off.
Components like inductors and capacitors on the motherboard aren't powerful enough to generate audible sounds. A computer virus could alter BIOS settings, but updating from a reliable source is a safer approach. Modifying processor power consumption to create noticeable coil whine is not feasible with current technology.
While a virus might affect the BIOS, you can obtain updated BIOS files from reputable sites and install them on a USB drive or CD. Capacitors are simple energy storage devices, not capable of producing sound or altering hardware functions.
VGA cables are typically shielded to prevent external interference with display quality. The wiring is designed to block unwanted signals, ensuring the image remains clear. Even if an external signal were picked up, it would only travel in one direction—from the monitor to the VGA card—and wouldn't corrupt data effectively.
Monitor-to-VGA communication is limited to retrieving resolution information and doesn’t allow for malicious infection or modification. The new computer has been purchased, but fan noise can sometimes produce unintelligible sounds. More probable causes include carbon monoxide exposure or other environmental factors.
