A friend of mine asked me to take a look at her computer. She said the computer was unusually "quiet" and would reboot itself on occasion. I surmised correctly that the fan on her power supply was faulty. She was a chain smoker and apparently smoked a lot while working on the computer; not only was the power supply fan gummed up with revolting tar and nicotine, but the CPU's cooling fan was clogged beyond use, and the cdrom drive drawer would not open. This is the only computer I have ever worked on that died from smoking.
In reply to the above anecdote of stupidity, a reader sent in the following:
I've seen a computer die from smoking, too.
A customer came in with a dead computer, claimed it was under warranty, and asked if we could fix it. We had look at it, and before we even laid eyes on it, we could smell it. Imagine the stench of an overused ashtray times ten.
We looked at the yellow case (it was supposed to be beige) and the date of purchase (3-4 months previous) and goggled in disbelief that she actually had any lungs left.
"What are you doing with this computer?" I asked in total disbelief.
It was at a taxi service. She smoked, the cabbies smoked, and the room was apparently only about eight by twelve. Smoking took place 24/7 in this place, and her fingers and the computer bore witness. We opened the case, and there were visible deposits of brown tar everywhere. The whole thing was gummy and slimy inside.
We had to tell her she was on her own. Naturally, she countered with the "it's under warranty" argument, but the computer was well beyond that. She left quite mad. We insisted she take her computer with her when she left.
