That reminds me, the dog is just reaching the end of her month long, twice a year shedding... Need to vacuum the fridge, freezer, and check the vent holes on the computer.
I used to admin a unix server that was in a very dusty environment.. under a desk in a carpeted office that was in the middle of a redwood forest. Not long after I took over the machine, I had to shut it off for a couple of hours. When I turned it back on, it would only run for about five minutes before it would crash hard. Having learned long before to check the obvious first, I popped open the cover. Sure enough, all the vents were practically blocked, the case was full of dust mice, and one of the cpu fans was not turning at all. Vacuumed out all the dust, popped off the heat sinks from the cpus, took them outside, and blew into them. A huge mushroom cloud of dust resulted. After I cleaned it all up and buttoned it back together, the thing ran just fine.
