The computer has a lot of dust, can I clean it up by myself?

In this way, bacteria will not grow, and computer knowledge will not be sick.

One: Simple cleanup.

1。Open the chassis. For the sake of "just in case", wear latex gloves as much as possible (don't learn from me: "use your hand to ground discharge" instead of "latex glove insulation") to avoid static electricity in your hands from breaking down the components (in case, it's troublesome).

2。In the face of "seeing is believing" motherboards, power supplies, CPUs, memory, discrete graphics cards, hard disks, optical drives (old hosts also have floppy drives), as well as data cables and power cables, remember the connection parts and cable characteristics by drawing.

3。Use "tweezers" to remove the "dust mass" from each part. Blow the power supply, CPU, and discrete graphics card "exhaust vents" to the ground (if it is reversed, blow it in), and use special tools (such as "rubber blowing balls", "leather tigers") to blow away the accumulated dust in each part.

First, there is no need to disassemble the hardware and plug and unplug the power and data cables. Main solutions:1.

Achieve a breakthrough of "0" (dare to open the chassis). 2。Strengthen the perceptual understanding of hardware.

3。Perform a preliminary clean-up of the accumulated dust. Computer literacy.

2. Comprehensive maintenance.

1。In addition to the motherboard, the power supply, CPU, memory, discrete graphics card, hard disk, and optical drive are "unmounted" and "cleaned and maintained". Replug the power cable and data cable to ensure that there is no false connection problem (because for the first time, do not "disassemble eight pieces" at the same time, so as not to mess up).

2。Because the memory and discrete graphics card "gold finger" are easy to oxidize, they need to be wiped with a high-grade eraser. Correspondingly, the slots need to be cleaned with a special brush.

3。As for whether you need to apply "thermal grease" to the CPU, because the CPU brand is different, please refer to the manual or ask the dealer (if you have already applied "thermal grease", you must not mistake it for "dirty" to scrape it off).

4。It is not advisable to oil the "cooling exhaust fan" of the hardware in question. If you don't get it right, it will cause: 1) "oil" to seep into the hardware and then damage the hardware; 2) The "oil" is aged and solidified, which affects the rotational speed.

5。Strengthen the bracket bolts in each part to prevent damage to components caused by loosening (even hard disks are high-speed equipment). Note:

Do not "screw" a bolt all at once. Should: four bolts, diagonally and gradually tightened; Two bolts, take turns to tighten step by step, until "tightened" firmly.

The second time, in fact, is the more formal host hardware "cleaning and maintenance". Speaking of which, hearing is not as good as seeing, and empty talk is not as good as doing (notebooks are similar to desktops, and the specific methods are bypassed). It is recommended that netizens who have not carried out any "cleaning and maintenance" on the host hardware should make up their minds to achieve a breakthrough of "0":

Try it and you'll succeed.

You need to go to the computer *** to hand over to the after-sales cleaning, and there will be some trouble in cleaning it yourself

1. Open the main chassis: first unplug all the wires of the main chassis. There is no need for a screwdriver here, and the general main chassis can be unscrewed directly by hand, here are four large screws, use your hand to unscrew it to the left (loose left and tighten it right), and then remove the main cover on one side by hand.

Just go to the side piece.

2. I have a piece on the right side (a piece with heat dissipation holes).

3. Remove the radiator: After opening the main chassis, you can see the radiator, which is a small electric fan, and you need to remove it. Rotate a few knobs around the radiator in the same direction (generally loose left and tight right), and then hold the radiator with your hand, and you can take it out with a little force (it is easier to swing left and right).

4. Remove the metal sheet of the radiator: After removing the radiator, there is a sheet of metal on the radiator, which has a lot of dust in it, and it only takes a little effort to remove this radiator, rotate it left and right, and rotate it outward to take it out.

5. Clean up the dust of the radiator: after the heat sink is removed, you will see that there is a lot of dust inside, which affects the operation of the radiator, thereby affecting the heat dissipation effect. Use a brush to clean up, and then use a hair dryer to blow it until the dust is cleaned.

6. The radiator dust is cleaned up: it will be cleaned up soon, it is better to use a combination of a brush and a hair dryer, the brush will brush down the dust or the brush is loose, and then the hair dryer will hang down, and it is best to use a hot gear to use the hair dryer, but not too hot (medium heat).

7. Clean up the CPU and motherboard dust: The dust is mainly concentrated on the radiator, but there is still a lot of dust on the motherboard and CPU, use a brush to brush off most of the dust or loosen the brush, and then use a hair dryer to blow (medium heat is better) until the motherboard and CPU are cleaned up.

8. Clean up the CPU and motherboard: After cleaning, the CPU should be bright and the dust on the motherboard should be less, so that it is completed, and after the cleaning is completed, you can install the radiator. Apply thermal grease to the CPU.

9. Install the radiator: This is the key, when installing, it is not as easy to get as when you take it off, here is a little trick. Turn several fixed knobs to install the radiator in the same direction (generally loose left and tight right), loosen, and then align the radiator with a few empty inside, insert a few holes into it first, use a screwdriver to press and hold a tubular thing at the bottom of the fixed foot, and then press and hold the remaining fixed foot into it.
