What other major PC component actually fails on a regular basis?

Batteries and fans, I guess.

Everything else doesn't really fail unless the user does something silly (toasting it via overclocking/overvolting) or a capacitor leaks.

Spinning-rust HDDs used to fail a lot because they were well, moving parts with incredibly small tolerances and computers get banged around sometimes.

It's kind of funny that SSDs carried on the tradition of failure despite not having moving parts.
