Why does stuff get dust on it when you leave it around?

Since you asked, I'm going to tell you (and please confirm this with a second or third source if you think I'm just trying to disgust you!);  Most of that dust in your house is little tiny bits of skin that have dried and flaked off of you and your fellow dwellers, plust the carcasses of dust mites!\n\nYou asked!\n\n(There is actually a whole book written about dust, and called, imaginitively enough, "The Secret Life of Dust" by Hannah Holmes.  Enjoy!)

It may be from dust build up.  A lot of cheap laptops have internal setups that hold a lot of dust in. You may want to try and buy one of those compressed air cans and spray thru the vents in your laptop every once in a while.

1) Sand grains are too heavy compared to bits of dust. Gravity overcomes cohesion and adhesion in their case. Dust, on the other hand, is light enough to get blown around by the breeze your legs create when you walk through the room. As the bits are blown around, they collide with each other and get hung up on each other. As sand gets blown around, it just falls down again.\n\n2) Also, unlike the building blocks of dust bunnies, sand is not dead cells shed from humans and other animals. Most of the dust your body produces probably has enough skin oils to create a little bit of stickiness.

Two reasons: dis-similar materials and it is an insulator.\n\nHere's how: When you drag a plastic comb through your hair, or rub a ballon against your hair or take a nylon coat off while wearing a polyester sweater, you are rubbing two different materials together.\n\nOne material has a slightly greater affinity for electrons and picks up some from the surface of the other material.  So one item ends up being negatively charged and the other ends up being positively charged.  This enables you to stick the charged ballon to the ceiling, but it also gives you a static spark when you touch something grounded like a light switch.\n\nJust like rubbing your feet (while wearing shoes) on the carpet to zap another kid back in school.  You can build up 1,000-2,000 volts of static electricity (at a very, very low amperage!).\n\nIf the material were a conductor, the charge would be carried away.  So it does not happen with metals.\n\nIt only happens on dry days because humid air bleeds off the charge.  So we mostly notice the effect inside during winter when our heating systems create dry indoor air.\n\nThere are anti-static sprays sold for computer users for carpets and clothes that make them a little bit conductive.  "Anti-cling" sheets to add to the clothes dryer do the same thing.

If your processor is making loud noises, you would need to open the case and air blow the dust that's cluttered in your processor.  Dust gets collected in there, and it's good to dust it out often.

Dust is bad for you computer. The fan could in the long run stop working and would cause the cpu to ovderheat which could cause the cpu to stop working or worse.\nPurchase a can of compressed air. \nShut down you computer.\nUnplug your computer from the outlet.\nOpen the computer case and spray the dust off. Keep the nozle of the can 20 inches away from the cpu.\nAlso you might want spray the fan of the power supply and inside the case in general.

I think its bcoz of some lyophobic particles present... im not sure..... jus guessin...

Check to make sure the air vents on your PC are free of dust.  It could be over heating or your power supply could be checking out.

use a cotton bud and when not in use push it through all the buttons and down the sides, a cheap and easy way to get rid of dust etc.

Huh?  Dust does not affect charge coupled device operation.\n\nPlease clarify your question

I call it proper punishment.\nIf you touch something and get grounded, you probably shouldn't have touched it. Didn't momma teach you not to touch things that don't belong to you?\n\nYou're discharging a static electricity charge from your body to ground. \nAs you walk around your shoes build a static charge on your skin. If the humidity is low your body doesn't discharge the static as readily as it would if it were more humid.\nWhen you touch something metal your body is discharging the energy back to earth.

Equipment you use, materials you throw out.  Think of a bulldozer (equipment) pushing dirt (material).  You keep the bulldozer and get rid of the dirt.\n\nGood luck.

Yes, the random movement causes the particles to move away from each other.  It is a random process, but over time it will happen.  Think of letting gas out of a balloon.  Within a few minutes the gas will be evenly distributed around the room by the random vibrations of the particles.

You should find the source of the dust; most likely it's from within the house such as carpeting or even dust that has built up in the ducts of your HVAC system.  \n\n1) Replace old carpeting or vacum it thoroughly and regularly with a high quality air-purifying vacum.  \n2) Replace the filters in your HVAC blowers/fans with high-quality air purifying filters.\n3) Have your HVAC system cleaned.

When it is cold and dry outside, the friction of your car going through the air creates static on your car. When you get out, you provide the shortest path to ground and the static electricity goes through you. If you hold onto the metal on your door while you are getting out, you will not be shocked.

your computer hard drive is about totally filled up.\ntry running your clean up programs.\nAnother thing, some anti virus soft wares, have extras for .the puropse of privacy and other stuff.\nIf they are starting to detect stuff harm full to yourPC,they will get in the way of things, and even stop it cold.
