How to clean computer hardware?

With frequent computer use, a large amount of dust will accumulate on the hardware, affecting the computer's heat dissipation and performance. PHP editor Zimo brings you a detailed guide to cleaning computer hardware, from preparing tools to specific steps, to solve dust problems step by step. If you want to keep your computer running efficiently, don't miss the following content.

1. How to clean computer hardware?

Remove the screws and open the host panel. We can use a hair dryer or vacuum cleaner to blow away most of the dust on the edge of the chassis. The remaining dead corners can be wiped carefully with an electric toothbrush.

I don’t recommend using a hair dryer in the position of the fan, because there is a lot of dust inside the fan. If you use a hair dryer rashly, it is likely to fly dust all over the place, so using a vacuum cleaner is the most appropriate choice. Then use an electric toothbrush to polish it to clean out some strongly attached dirt, and continue to use a vacuum cleaner to clean it. This kind of cleaning effect is completely better than air blowing. 2. Computer hardware upgrade sequence?

I have a Lenovo B450, the basic configuration: CPU is Celeron T3100, memory 2G, integrated display 512m.

I should have bought this phone six or seven years ago. It is already very old. It often freezes after about a minute of being turned on.

For the win7 system, I tried my best to protect it, even reinstalling it was useless.

Considering that the mechanical hard drive is aging and other hardware cannot keep up, we finally upgraded with the attitude of treating a dead horse as a living horse.

First use CPU-Z to query the motherboard information. I decided to use P8800 for the CPU. I originally wanted to use T9300 or T9500, but I was afraid that the notebook’s cooling system would not be able to keep up and the temperature would be too high. Add one more 2G memory, for a total of 4G. Buy a 30G solid state drive to install the system. Except for the solid-state drive, all the above are new and cost about 120 yuan (plus optical drive bracket).

The CPU and memory are both in stock, and the price for both items on TB does not exceed 100 yuan.

Disassemble the machine, clean it, re-apply heat dissipation silicone grease, install the machine, and install the system. Now it only takes 13 or 14 seconds to boot up, surfing the Internet, watching movies, office software, CAD, etc. run smoothly. The total cost of the above is about 220 yuan. The above is for reference only. If you want to mess with it, you must know the knowledge of hardware installation and system installation.

3. Haier computer hardware upgrade?

You can directly buy a 2GB memory. After installation, the memory will be expanded to 4G. Upgrading the graphics card is much more troublesome. Your machine's graphics card is directly welded to the motherboard. If you want to replace the graphics card, you can only replace the motherboard together. Memory can be bought for tens of dollars.

You can clean the heat dissipation yourself, or you can choose a professional store. There are detailed graphic and textual explanations for cleaning laptops online. When I disassembled the machine in a professional store, the price was 50, and it won’t be much different elsewhere.

4. Upgrade the computer hardware configuration?

There are many factors to consider, including budget, performance requirements, personal preferences, etc. The following are some common upgrade methods:

Memory upgrade: Memory is an important part of computer performance. Upgrading memory can improve the computer's running speed and multi-tasking capabilities. It is recommended to choose memory modules with the same frequency and capacity to ensure compatibility and stability.

Hard drive upgrade: The hard drive is an important part of the computer for storing data. Upgrading the hard drive can improve the computer's storage capacity and reading and writing speed. It is recommended to choose a hard drive with the same or larger capacity to ensure compatibility and stability.

Graphics card upgrade: The graphics card is an important part of the computer's graphics processing capabilities. Upgrading the graphics card can improve the computer's graphics processing capabilities and game performance. It is recommended to choose a graphics card with the same or stronger performance to ensure compatibility and stability.

CPU upgrade: The CPU is the core component of the computer. Upgrading the CPU can improve the computer's running speed and multi-tasking capabilities. It is recommended to choose a CPU with the same or stronger performance to ensure compatibility and stability.

It should be noted that upgrading hardware requires consideration of multiple factors, including budget, performance requirements, personal preferences, etc. It is recommended to conduct sufficient research and comparison before upgrading to choose an upgrade plan that suits you.

5. Where can I wholesale computer hardware?

If you want to wholesale computer hardware, you can consider the following ways:

1. Electronic product wholesale markets: These markets usually gather many electronic product wholesalers to provide wholesale services for various computer hardware. For example, Huaqiangbei Electronics Market in Shenzhen, China, Zhongguancun Electronics Market in Beijing, etc. In these markets, you can find many hardware wholesalers with more varieties and prices, but you need to pay attention to product quality, after-sales service and other issues.

2. Online e-commerce platforms: Such as Taobao, JD.com and other e-commerce platforms. There are many sellers on these platforms providing wholesale services of various computer hardware. You can use these platforms to find corresponding sellers and contact them to compare prices and quality, and choose the wholesaler that suits you best. It should be noted that you need to pay attention to the authenticity of the product and after-sales service issues.

3. Contact the manufacturer directly: If you want to customize hardware with special specifications, or purchase hardware of a certain brand in large quantities, you can contact the manufacturer directly for wholesale. This way you can get better prices and after-sales services, but you need to pay attention to the credibility and strength of the manufacturer.

It should be noted that no matter which way you wholesale computer hardware, you need to pay attention to product quality, after-sales service and other issues. Only by choosing a regular and reliable wholesaler can you ensure product quality and after-sales service.

6. How to detect computer hardware?

Commonly used methods are as follows:

1) Direct observation method: Inspection by touching with hands, seeing with eyes, hearing with ears, etc. Hand touch: The normal temperature of the shell of general components is between 40°C and 50°C. Except for the CPU that requires a fan to cool down when the temperature is high, other components should not be hot under normal circumstances. Visual inspection: Check whether the connectors and jumper pins on each control board and card are inserted upside down, loose or short-circuited, whether the data cable is plugged in place or correctly, and whether the function selection switch is set correctly. Listen: Listen for any abnormal sounds when turning on or running. For example, if you hear a long "beep-beep" sound when you turn on the computer, it means that the memory module is not inserted properly, or there is a problem with the memory module. For example, if you hear a "beep-beep" sound when you power on, "One is long and the other is short, that is because the graphics card is not inserted properly. If a problem is found, it should be shut down immediately for maintenance.

2) Plugging and unplugging method: This is a method of identifying faulty components by unplugging and plugging in some plug-in boards in the machine. After each piece is pulled out, turn on the machine and check the status of the machine to find out the fault. If there is no fault display during startup, you can also unplug all plug-ins and peripherals first, leaving only the motherboard and graphics card. If the startup is normal, then plug in various boards and peripherals one by one to check until the crux of the problem is found. .

7. Computer hardware detection software?

1. CPU test software, it is recommended to use SUPERpi, or the chess master test program, and the detection software is recommended to use CPU-Z

2. Memory test: memTest, this is currently recognized as a better test software

3. Power supply test: OCCT, this is of course also recognized

4. Graphics card: Of course it is 3DMARK software. The most recognized testing software in the industry is this software

8. How to install computer hardware?

1. Install the chassis. This step is mainly about unpacking the chassis and installing the power supply in the chassis.

2. The motherboard is an important part of the installation. Install the motherboard properly in the motherboard position of the chassis, then insert the CPU to be installed into the motherboard processor socket, and also install the cooling fan.

3. The next step is to install the memory module, which is mainly to insert the memory module into the memory module slot on the motherboard.

4. The graphics card is an important component of a computer. During installation, we need to select the appropriate slot according to the bus of the graphics card in order to select the appropriate graphics card.

5. Next, install the sound card and driver. The sound card is relatively simple. Just choose a sound card with a PCI slot that is generally popular on the market. As for the driver, the installation of the hardware, optical drive and floppy drive is relatively cumbersome.

6. Start connecting the data cables between the chassis and the motherboard, including the installation of various cables such as indicator light power switch cables.

7. After completing these, you can consider closing the chassis cover, but because we still need to check the chassis problems, it is best not to cover it, and you can do the final work after the work is completed.

8. In this step, connect the output device and display device, including mouse, keyboard and monitor. And check the entire process on the side to see if there is any flaw in any link. If not start testing.

9. Power on the machine, and the display screen will start to work normally, which also proves that the initial installation of our computer has ended. Precautions for computer hardware installation: 1. The principle of static electricity cannot be violated during the entire process.

2. Pay attention and direction, use moderate force when assembling, and change the direction when inserting the board. 3. Don’t miss some components, all screws must be installed, not one is missing.

4. Do not touch the motherboard circuit board with your hands. 5. When inserting cards and connecting hardware, do not touch small components on the motherboard. 6. Anti-static. The gaskets of the screws on the motherboard should be put on to prevent static electricity.
