It's like you get dust in the connectors, the resulting resistance creates heat and it's all over.
Naah, what usually happens is the copper contacts get tarnish or corrosion on them over time and that causes the resistance. Heat causes more resistance, which causes more heat and eventually you have fire.
I've had hard drives go on fire because the motor and head stack contacts got the same problem, which is exacerbated by the foam insulation which usually holds moisture and accelerates the process.
Many of our customers are fast food restaurants. Some come back with a layer of grime that looks like it was too close to the deep fryer. More often though the CPU fan ceases and the CPU overheats.High humidity can cause copper to tarnish rather quickly, depends on the environment.

found a fried mouse in a pc at a pizza place yet? "we dont know what happened. we were taking ordered and it just turned off!"Yeah, been there. I do service calls for a local fast food restaurant chain and constantly have to repair things that have been sludged with grease. Wire runs above the ceilings are a nightmare because rodents eat the wire due to grease condensing on them.
Their back office PCs are a constant nightmare, have to be completely gutted and cleaned once a year.
