"Yeah, my computer's been running a bit slow lately" โ meanwhile their CPU cooler has evolved its own ecosystem. That's not dust, that's a sentient being about to achieve consciousness. The CPU fan is basically a felt sculpture at this point. The RAM slots have their own insulation. There's enough biomass in there to start a compost pile. I'm genuinely impressed the motherboard still POSTs โ that thing deserves a medal for surviving what looks like a decade in a sawmill. Tech support rule #1: when someone says their PC is "a bit slow," prepare for archaeological discoveries. This is why we charge diagnostic fees, folks. Hazard pay.
