How about a slow, lingering death due to a wasting disease? Had an old floppy disk controller do that during the Great Flood of 1993.
Our local area power substation was flooded out sometime in July. After a long initial area-wide blackout and a couple of days of rolling blackouts, the power company decided to put a diesel generator in to replace the capacity until the flood waters receded and they could repair the original facility. They got the generator, plugged it into the local electric grid, set up a supply line for fuel and assigned National Guard troops to keep it running.
As far as I know, it only ran out of fuel once over the next two months, so the Guard certainly did their part in this. But you can imagine what kind of power we were getting through our wall outlets - "dirty" doesn't begin to describe it.
I would be typing away on my monochrome monitor (using WP 5 under DOS), and suddenly all of the characters on my screen would begin to dance (think HampsterDance in black and white...). This would continue for a couple of minutes and then things would settle down again for a few hours or so.
This went on for a couple of weeks, and then I noticed that my floppy drive was acting weird. I could still write things to disk, and I could read some of my disks, but some of them would fail, usually with "Bad Sector" messages. Eventually all reads began to fail, and that ended my write capability as well.
Husband pronounced it Dead (it was an ancient machine) and we finally got an updated system shortly after the floods receded and the power grid problems were resolved. It was then that I realized that every disk that I had written to during that period was unreadable and unuseable; they all were "Unknown" to DOS and couldn't even be reformatted.
It seems that the dirty power caused something to happen in the controller which made the boot sector read/write process "move" by some small amount. Every time I wrote something to the disk, it shifted the track0 info just enough to put it out of sync with a normal drive; eventually, it moved far enough to cause the drive to quit reading anything, even its own "reformatted" disks.
On a related note, the following two summers saw massive failures of central air conditioning units in the neighborhood, all involving units that were less than 5 years old (under warranty). When our neighbor's system failed, she contacted her HVAC people; to her surprise, they told her, "We've been expecting a call from you. We'll be out later today to replace the dead part." Seems that after the fourth or fifth call, all requiring the same fix, these people got smart and contacted their supplier to get an immediate shipment of components to keep on hand. They had to wait for a failure to meet warranty requirements, but they were very quick with the replacements.
The failing part? The little computer module that controls the energy-efficiency sensors that all modern systems use to cut down on electric usage. Yup, it didn't like dirty power any more than my computer did.
It took about two years to get all of the systems cleaned up. We were told at one point that the supplier had filed a lawsuit against the power company in an effort to recover what they could in costs for the replacement units, but I don't know if they ever got anything for it.
The flood was an "act of God", but the power substation failure was preventable; if you build a major substation in a flood plain and don't protect it from flooding, at some point it's gonna drown. (They built a 500-year levee around it once they got back out there, so I suspect that they had more than a few lawsuits filed against them.)
Makes me wonder what might happen on the left coast this summer after all of the rolling blackouts and brownouts they've had. If you have a fairly modern AC/heating system, you might want to get it checked.
