Pay attention to computer dust removal. As many people know, computers are very easy to produce dust. If the computer is not dusted for a long time, it will affect the service life of the computer and affect people's skin. Here are some points for attention in computer dust removal!
Precautions for computer dust removal 1 Precautions for computer dust removal.
For most ordinary users, the chassis will not be opened once for a long time, let alone clean the computer. Now the weather is hot, and many users begin to find that their computers crash and restart frequently.
The accumulated dust has finally begun to play the role of "heat insulation", and it is strange that the computer is not dead. Pick up the brush and tiger quickly, and let's clean up the equipment in the computer case.
Radiator component
The radiator on the CPU and graphics card is simply a vacuum cleaner, so we should clean it up first.
Remove the CPU radiator, then remove the fan of the radiator (usually fixed with plastic fasteners or screws), and clean the dust on the fan blades with a brush, both sides should be cleaned.
Next, radiator. If the dust has accumulated into a ball, it is suggested to buckle the radiator on the ground in the opposite direction, shake off the big dust ball, and then remove the rest with a brush.
If the dust in some gaps can't be brushed off, you can consider washing with water, as long as it is completely dry after washing.
The radiator of the graphics card can also do the same thing, but it is difficult to remove the radiator of the graphics card, which requires a certain degree of hands-on ability. Ordinary players can do what they can. If they can't get it off, they can clean the fan and dust with a brush.
Important note: the heat sink can be washed, but the fan should not be washed-because it is difficult to dry water when it enters the motor. In addition, some silicone grease must be added to the bottom of the radiator before reinstallation to ensure good contact effect.
Cardboard parts
In addition to the radiator with cracks everywhere, boards full of components are also big eaters. You can see that the CPU power supply circuit part of the motherboard and the part where the radiator airflow passes on the graphics card are covered with dust. It is recommended to take the whole motherboard out of the chassis and clean it.
In addition, the PCI-E slot and SATA interface should also be cleaned, which is easy to accumulate dust, resulting in poor contact when the graphics card or SATA cable is plugged in again.
Important: Do not wash with water!
The radiator can be washed, but the board should not be washed. Although it can be washed in theory, the difficulty lies in how ordinary users dry it ... the water droplets in the gap between those components and solder feet are difficult to deal with, and some metal contacts will rust.
Therefore, it is safer to treat the dust on these parts with brushes and leather tigers.
Chassis parts
It's best to take all the accessories out of the box and do a thorough cleaning. The bottom of the chassis, the front air inlet and the rear air outlet are dusty places that need to be cleaned. Just use a brush and a leather tiger here. If some places are really dirty, you can use a semi-wet rag dipped in detergent to clean them.
Important note: Be careful that your hand is scratched by the inner edge of the chassis, especially some low-grade chassis, the edge is very sharp, so be careful when using the rag.
Other parts
Dust accumulated on the shell of hard disk, optical drive and other equipment should be wiped off with a slightly wet rag first, and then wiped with a dry rag. It is not allowed to wipe the exposed circuit board with a wet rag.
Besides these precautions, you should be more careful when cleaning the computer. Remember the location and sequence of installing and disassembling accessories, and don't lose screws and fixing fasteners.
Of course, please wear a mask when cleaning, the dust flying everywhere is really not covered ... After cleaning, you will find that the working temperature of your computer is greatly reduced and the noise of the fan is also reduced a lot.
Precautions for computer dust removal II. Precautions for computer dust removal:
1. Many friends like to clean the dust with brushes. In fact, this method is not the best, because the hair on the brush will contact the hardware, which is easy to cause damage to the hardware. The best way is to use a skin blower or a hair dryer, which is really not good. Otherwise, the hair on the brush must be soft.
2, for the stubborn dust in the computer, you don't need to be too entangled, you can completely ignore it, because they often don't have much impact on the computer.
Please don't unplug the hardware in the computer when it is unnecessary, which is more likely to cause hardware problems.
Some Suggestions on Cleaning Computer Keyboard
1, hit the keyboard
Turn off the computer and remove the keyboard from the host. Put a newspaper on the table, put the keyboard down, about 10 cm away from the desktop, pat and shake it. You will find a lot of "inventory" falling out of the keyboard: besides dust, there are biscuit crumbs, coffee powder, rubber crumbs, hair and so on.
Step 2 blow off debris
Use a hair dryer to blow away the debris attached to the keyboard keys, and then turn the keyboard upside down and shake it.
Step 3: scrub the surface.
Some people are used to scrubbing the keyboard with a wet rag, which is quite clean. It seems unnecessary to use special computer cleaner.
However, although wet rags can remove some stains and viruses from the keyboard, most viruses will still remain on the keyboard, which will continue to endanger the health of computer users. At the same time, the moisture in the wet rag is likely to penetrate into the gap of the keyboard under the pressure of the scrubber, resulting in oxidation or rust of the keyboard parts.
The advantage of using special cleaner for computer is that its foam cleaning method will not scratch the computer surface, nor will it penetrate into the keyboard to destroy the protective layer, and it can completely kill viruses and bacteria and protect human health.
Step 4 disinfect the keyboard
After the keyboard is scrubbed clean, soak it in alcohol, disinfectant or medical hydrogen peroxide for disinfection, and finally dry the keyboard surface with a dry cloth. In addition, if alcohol is used to "care" the computer, it is likely to corrode the protective layer on the surface of the keyboard and reduce its sensitivity while sterilizing.
5, thorough cleaning
If you want to clean the keyboard thoroughly, you must remove the cover of each key.
The key cap of ordinary keyboard is detachable. You can pry them off with a small screwdriver or ear spoon, one by one from the corner of the keyboard area to the middle. Space bar, enter key and other large keycaps are difficult to return to their original positions, so try not to remove them.
In order to avoid forgetting the location of these keycaps, it is best to take a picture of the keyboard layout with a camera or draw a sketch. After the keycap is removed, it can be soaked with detergent or disinfectant, and the keyboard base can be carefully scrubbed with flannel or disinfectant paper towels.
How to avoid keyboard poisoning
First of all, to develop good personal hygiene habits, wash your hands before and after using the computer; After using someone else's computer, it is best not to rub your eyes and pick your nostrils before washing your hands;
Don't eat while operating the computer. Secondly, it is best to buy the plastic cover of the keyboard, cover it with the front of the computer and replace it regularly to reduce the chance of keyboard pollution and spread diseases.
