[QUOTE="Barabas"]\nDust can kill all hardware, why do engineers wair dust protection when\nthey are building a sattelite for example, same reason? Dust partikels are\nthat large that they can contain Iron (Fe) molecules. One dust partikel\nisn't probably going to hurt your hardware but once the dust deposites get\nbigger and bigger they will be able to make contact at some point,\nresulting in short cuts.\n\nThis is why you should clean all hardware!!\n\nEach year thousands of people get killed because there TV screen implodes,\nsame reason, hardware never gets cleaned and becomes a deadly bomb waiting\nto go off at some time.\n\nGreetz\n\nBarabas\n\n\nThe group's discussion of proper cleaning technique has been helpful,\nbut can anyone explain why dust can cause electrical problems with the\nsystem's components. As well, either by their nature or design are\nthere particular components in a typical computer that are more\nvulnerable to dust related electrical problems?\n[/QUOTE]\n\nDepends on what the 'dust' actually is. Most household dust is dead human\nskin cells, but in certain environments dust may be from a completely\ndifferent source and it's possible the dust could be from a conductive\nmaterial.
