As the days get warmer, the house has been getting warmer [I am in that sweet period of no heat and no A/C and low utilities bills that happens every Spring and Fall], and I have been having video anomalies and messed up screens when the room gets warmer. Yesterday in fact I had several occurrences before the card failed. And then looking at how much dust was clogging the ducts and heat sink on the video card, and that it was basically occluded so that very little cooling air from the fan was blowing over the heatsink; based on experience, electronics get hot, and if they get too hot, they fail, and one way to get them too hot is to restrict or minimize the flow of cooling air over them. It is not a scientific explanation with lab analysis and component level analysis, but it fits the circumstances better than other possibilities. _______________________________________________ MacOSX-talk mailing list [email protected] http://www.omnigroup.com/mailman/listinfo/macosx-talk
