One reason of 'component' failure can be high temperature. When your 'pc' is mostly in the office it may not get too hot, but do you run the airco 24 hours a day? Do you sometimes 'clean' the box on the inside? Note 'box' can be 'desktop pc', 'server', 'notebook', etc.

I'm not saying your 'box' looks like this, but if it did you're asking for troubles building up.
