That's true, but in many cases, it's not the integrated circuits (ICs) that fail, because they tend to be quite reliable. It's more often the capacitors, resistors, storage devices and power supply components that degrade over time. Capacitors, in particular, can fail due to heat, aging, or voltage surges, which can lead to failure in devices even if the ICs are still in good condition. Power sources can also fail due to wear on these exact components.

I've seen enough electronics repair videos that it seems the default for troubleshooting absent other conspicuous damage is to start checking the electrolytic capacitors.

There was a time when Gigabyte started selling more robust motherboards with quality capacitors that would last much longer. After seeing so many old motherboards dying from blown capacitors I was very happy to get one. Those motherboards so far held the full length of their meaningfull life until the CPU just got too slow to use for anything. Still try to look for that type of capacitors when I build new stuff for friends and family.

The Gigabyte line is called "Ultra Durable" and have solid capacitors instead of the electrolyte ones.

And the electrolyte can and will start to leak and foul the ICs around them, if not by ruining the traces/pads, then they can also foul the legs and/or find their way into the chip package itself, so the ICs will fail as a secondary issue.

So better to turn it on sometimes, without power cycling so much, to keep the electrolyte fluids wet, to extend the equipment life. Let it rot and dry and it will.
