Just some wild guesses to think about or check.
This is just a wild stab and extremely unlikely, but did you get a new phone or some other wifi or bluetooth aware device in the last year or so?
Is there some electronic devices that you carry everywhere regularly?
Go stand by some audio equipment that has a long microphone cord with a turn up microphone and see if you notice some odd sounds that fade when you walk away from the cord.(hopefully it's constant.)
I doubt your a HAM or hobby radio operator, but if you are did install a radio in your car or start carrying around a radio?
This is supposed to be cured or much improved in modern(post 1990's) computers, but in the past static electricity could cause instabilities in a computer even when all you touch is the outer metal grounded case.(The large electrical current flowing into ground could cause bit errors in circuits or in data being written to the hard drive, since most windows computers used hard drive memory caches it could on very rare occasions corrupt programs and cause hard drive problems.)
Also in the past few years I"ve noticed USB ports sometimes suddenly failing when some device was plugged into them. Most of the time when I checked the conditions were right for static electricity when the USB device was plugged or pulled.
Do all the failed computers have a location in common? Such as your car or office or house?
The kicker is that the static shocks can create cumulative damage that won't show for some time and the Device your plugging in may itself never be damaged.
Did you have a habit of plugging in something into the ports of all these computers?
Something as simple as new shoes, car seats or even clothing(got a favorite pair of pants) have you notice yourself being shocked by static charge more than normal in the past few months.
How did the hard drives fail? Just corrupted files or head crash and/or surface defects?
Hope this gives you some ideas
