What can fail due to the dustiness of components inside a computer, laptop, or monoblock? What preventive actions are necessary to prevent damage to computer equipment due to dust?

What can fail due to computer, laptop, or monoblock dust?
  1. The motherboard of a stationary computer or laptop may fail due to dust.
  2. The video card of a stationary PC or laptop (video card chip).
  3. Power supply unit. Most often, it is a stationary PC unit. The laptop power supply is hermetically sealed from dust and does not need maintenance.
  4. Chipset. The north and south bridges of the motherboard chipset are vulnerable to dust and subsequent overheating.
  5. Laptop battery. The laptop battery works much less during long-term operation in an overheated laptop.

What is the danger of dust inside the computer?

Household dust in its normal state is a dielectric, i.e., a substance that does not conduct an electric current. We often don’t notice it, accumulating peacefully in our system unit or laptop. Usually, this harmless process continues for the time being. Then the problems begin.
Oddly enough, house dust turns out to be the worst enemy of the desktop and has several other interesting qualities and properties that can affect electrical circuits and components. The laptop cooling system and open areas of the printed circuit board are particularly sensitive to it.
Therefore, the best option is to try to avoid dusting, and if this happens, clean the laptop from dust as soon as possible.

  • The first negative property is that dust mechanically clogs the cracks and channels to remove warm air generated when heating components of a computer or laptop. Most often, this becomes noticeable after a certain period of laptop operation. It makes a lot of noise, gets warm, and sometimes turns off after some time under load.
    • The second bad quality is that dust becomes a conductor of electricity under certain conditions. This happens if the room is not heated enough in winter, the computer is transported in the car at a negative temperature, or it has been damp and cold for a long time.
    Based on the knowledge of the basic properties of dust, which can negatively affect the operation of the computer. Anything can break down in a computer or laptop, starting from a power supply and ending with an expensive high-performance video card, because almost all components heat up and, at the same time, are sensitive to resistance in the circuit and short circuits.

Therefore, to prevent problems with the computer, dust must be periodically removed from its most sensitive areas.
To prevent the breakdown of the power supply, it is sometimes useful, even without thorough disassembly, to clean the surface from house dust with a brush with a long, stiff pile.
It is recommended to clean or blow the cracks near the cooler and inside the case. Once a year, a thorough cleaning with disassembly is desirable, including RAM slots and the back surface of the hard disk.
To prevent the motherboard from failing, it is advisable to clean the dust off the surface of the PWM processor on the motherboard. The PWM of the processor power supply is located inside the system unit and is very close to the CPU cooler on the left hand. For reliability, it is recommended to clean the entire surface of the site near the processor with a brush, as well as the cooler itself, to prevent overheating of the processor.

 

So, if you notice that your computer, laptop, or monoblock:
  • After switching it on, a strange smell appears;
  • Suddenly, it spontaneously began to turn off or reboot;
  •  It has become slower to work;
  • There was extraneous noise, or the noise level became higher;
  • Then, most likely, your equipment needs maintenance.
