Microwave oven's effect on a computer

Long before electromagnetic fields affected a computer, instead, nearby CRT type monitors would be significantly and obviously distorted; require degaussing. Some have suffered such problems even because a high current wire (ie to electric stove or central air conditioner) was inside the adjacent wall. But the problem is a distorted CRT display; computer still works just fine.

In one case, a direct lightning strike travels down a lightning rod wire only four feet away from a computer. Computer worked just fine; not even interrupted. Again, electromagnetic field did not cause computer damage.

Solution starts with some basic information such as what are and are not on same circuits. What/who is the source of power supplies (ie clone assembler or major computer manufacturer)?

Clearly there is a problem since normal power supplies operate over a decade without failure and since all computers must work just fine, without even a UPS, when AC electric voltage drops so low that room lamps are dimmed to less than 50%. Multiple failures in one location is far from normal. For example, AC power source is maybe one reason for failure. So is source of that power supply, source of the diagnosis (maybe none of those power supplies have really failed), etc.

As with all investigations, best evidence is in the dead body. Notice another essential feature exampled here. Reasons 'why' - reasons for what is required to get a useful answer and what could not create that failure - are also provided.
