Computer components don't fail
Oh dear. I would recommend dialling back your blind trust in components. In general, if something electronic has been working for 6 months you're OK, at that point the expected point of failure tends to move to mechanical parts such as connectors, spinning parts (hard disks, fans) and power supplies.
There has been a real scandal with electrolytical capacitors which expired quite quickly (look up "Capacitor plague"), and stuff like that will happen again as long as people are in search of short term profit.
Also, electronic components themselves are not free of latent issues - poor welds and internal wiring can also create a ticking clock as thermal movement eventually causes a disconnect.
So no, they DO fail. Not as often as before, but they do fail.
