Actually, today's hardware problems are often caused by buggy firmware -- software has taken control of the developed world. Cables and connections were always a problem area for hardware; now we need to think about whether problems are due to RF "interference", which could be a too strong RF signal from some other device, or poorly designed hardware that is not rejecting spurious signals. USB3 interference with 2.4 GHz devices <https://www.intel.ca/content/www/ca/en/io/universal-serial-bus/usb3-frequency-interference-paper.html> is going to be more common as el cheapo USB3 devices and cables become more common. If you suspect interference, turn off all but essential devices and see if the errors go away. If so, add devices back one at a time until the errors resume. If you have things like external drives, it may help to run a grund wire to bond the cases together with the system case. -- George N.
