Many years ago, when I took a day job as a CATV field engineer, we burned everything on a test desk for 48 hours or more if we had the time.

Occasionally, components would fail in the burn-in period. If they made it through the burn in, they would go out in the field and be installed on a utility pole or ground level locker.

It just seems that every once in a while a resistor, capacitor, coil, or IC would fail during the break in period. If it made it through that, it was probably reliable.

Much easier to replace something before it hangs on a utility pole 18 feet in the air.

So when building your own PC, I suspect there will be an occasional failure of components. It just comes with the territory.
