Computer Maintenance

Computer Maintenance Background Introduction

Computers have become an indispensable tool, and with the development of information technology, more and more system maintenance and management problems are faced in the use of computers, such as system hardware failures, software failures, virus prevention, system upgrades, etc. If handled effectively, it will have an impact on normal work and life. To this end, we provide comprehensive computer system maintenance services, so that you can exchange for a relatively stable system performance at a lower cost. A computer is made up of many parts, and only when these parts work together can it be called a computer. But its working principle has not changed, including motherboard, CPU, memory, hard disk, graphics card, sound card and so on. The following will briefly introduce the various components that make up the computer.

Types of computer maintenance

Computers vary in size and function. The number one computer in size and power is a supercomputer, a computer that is very large and contains thousands of connected microprocessors to perform extremely complex calculations. The last computer in terms of size and function is the microcomputer embedded in cars, televisions, stereo systems, computers and household appliances. These computers are computers built to perform a few jobs.

A personal computer or PC is a computer designed for use by one person at a time. This section will describe the different types of personal computers: desktops, laptops, minicomputers, PDAs, and Tablet PCs.

Computer Maintenance Desktop Computer

A desktop computer is a computer designed for use on a desk. They are generally larger and more powerful than other types of personal computers. A desktop computer is made up of several separate components. The main element is called the main unit, which is usually a rectangular box that sits on or under a table. Other components such as the screen, mouse and keyboard are connected to the host computer.

Computer Maintenance Laptop

A portable computer is a lightweight mobile computer with a built-in thin screen. Laptops run on batteries, so they're great for taking them around. Unlike desktop computers, notebook computers combine the CPU, screen, and keyboard into one machine. When not in use, you can also close the screen toward the keyboard.

Computer Maintenance Mini Computer

Mini Notebooks, also known as Small Notebooks, are small, affordable notebook computers designed to perform a limited amount of work. They are usually not as powerful as laptops, so they are mainly used for browsing the web and checking e-mail.

Computer Maintenance PDA

Handheld computers, also known as personal digital assistants (PDAs), are battery-operated, thin, and small enough to take almost anywhere. While not as powerful as a desktop or laptop computer, handhelds are great for scheduling appointments, storing addresses and phone calls, and playing games. Some even offer more advanced features like making phone calls or surfing the Internet. Palmtops don't have keyboards, but they have touchscreens that you can use with your fingers or a "stylus" (a pointer tool that looks like a pen).

Computer Maintenance Tablet/PC

A Tablet PC is a mobile PC that combines the functions of a notebook computer and a handheld computer. They have the same powerful features and built-in screens as laptops. Like a handheld computer, it lets you write or draw on the screen (usually with a tablet stylus, not a stylus). They also convert your handwriting into typed text. Some Tablet PCs have screens that swivel in and out, and can be flipped up to reveal the keyboard underneath.

Computer Maintenance and installation

Software Parts

• When the system is installed, the system disk partition should not be too large or too small. If it is too small, the C drive will often need to be cleaned up. In order to save trouble, I personally think that XP should be above 10G and below 20G, so that it can be used for a month or a few Clean up once a month. Except for necessary programs, try not to install other software on the system disk. The file format of the system disk should be NTFS as much as possible.

• Register your software. This is if you use the genuine version. If you use the D version, then you should try to download from some large and well-reputed green software stations, and try not to go to some small software stations. There are many people who like to try early adopters. When a new version comes out, they like to use it. Personally, if your old version can still meet your requirements and has been stable, you should not try it so quickly. Moreover, I personally feel that it is best to use only one software of the same kind. Many people's computer failures are due to software conflicts, especially anti-virus software and players. Some people think that the more anti-virus software installed, the better, but this is not the case. Two or more anti-virus software is installed in one system. It will cause the system to run slowly or even the blue screen of death, etc. After most players are installed, an acceleration process will be formed in the background. In fact, it will still download in the background when you do not use it. The old bird can be in the task manager. Seeing these processes, two or more players will rob each other for broadband, resulting in ultra-slow network speed. If the configuration is not good, it may crash.

• Customized automatic updates. Automatic updates can patch your computer's many vulnerabilities and can also protect you from some viruses that exploit system vulnerabilities. Of course, if your system is version D, please be careful to use a dozen patches, and your system will be games over.

• Read the section on maintenance in the manual. In fact, many common problems and maintenance may be in the manual. As a result, you have asked many people for help, but later found that the method is already by your side.

• Set up your email program to automatically archive old letters.

• Install antivirus software. Although antivirus software cannot be 100% antivirus, it is better than nothing. As I said before: cold medicine may not cure a cold, but unless you are in good health, you will not get better if you do not take cold medicine.

• Install anti-rogue software. There are also a lot of such software, and the use of different personal hobbies is different. I myself use the one that comes with the optimization master, and I feel that it can also prevent some rogue software. Speaking of which, I would like to remind some beginners that many shareware on the Internet are bundled with some plug-ins, and try not to choose to install them when installing

• Save any driver installation disks. The original one isn't the best, but it's generally the best. The latest driver may not be able to give full play to the performance of your old hardware. Don't pursue the latest version of the driver too much.

• Weekly maintenance. What to do Delete junk files, organize the files in your hard drive, and use antivirus software to thoroughly scan and kill viruses. Do a defragmentation once a month or so, and run a hard disk troubleshooting tool.

• Delete unnecessary files.

• Back up important files. Personally, if you have the habit of putting your files in "My Documents", then I suggest you transfer the storage path of "My Documents" to a non-system disk. Method: Right-click on "My Documents" on the desktop, select Properties, and you can change the storage path of "My Documents". The biggest advantage of this is that one day you need to reset the system disk and reinstall the system, and you will not be sad because your files are lost. Conditional can also use GHOST software to back up the entire disk to CD.

• Empty the recycle bin. It's a good habit to empty the Recycle Bin regularly. Or simply press shift+del to delete, so that it will not go to the recycle bin.

• Delete temporary Internet files.

• Don't put too many things on the desktop, and don't put too many shortcuts. The same goes for the quick launch bar.

• If you have other backup methods, disable System Restore as much as possible.

Hardware Parts

• Use a power outlet that is protected against current surges. Don't let your computer share an outlet with other high-power appliances in your home. And you must remember that your computer socket must use a real three-wire (that is, the one with a ground wire). Computer-specific sockets should be of good quality as much as possible, and don't save a few dollars. I have learned a lesson that the socket at home seems to be three-wire, but the ground wire is not connected at all. In less than half a year, my power supply was destroyed but not regenerated. At that time, I thought my computer was also scrapped at the same time.

• It is strictly forbidden to hot-plug various devices (except USB). If possible, speakers, headphones and USB devices should not be plugged or unplugged. Because the instantaneous current can easily burn out the motherboard, many motherboards using 801FB and 801DB South Bridge are burned out because of hot-plugged USB devices.

• Regularly clean the dust inside the case. It is recommended to do it once every six months to a year, because the dust will generate static electricity and some poor contact. Too much dust is also the main culprit for the poor air flow, especially the dust in the power supply.

• All behaviors of opening the case, please pay attention to electrostatic protection. You can discharge static electricity from your body by touching the contact metal first. Please bring electrostatic protection equipment if possible.

• Do not play with the computer while eating, especially food with juice.

• Don't put a lot of things on the case, especially putting too many things behind the case will affect the cooling of the computer.

• In general, do not move the case while the computer is working.

• Do not place the speakers too close to the monitor. Don't let the computer close to home appliances with electromagnetic radiation, try to keep the mobile phone away from the computer.

Computer Maintenance Content

In the process of fault phenomenon recurrence and maintenance judgment, the expansion of the fault range should be avoided;

During maintenance, check and check the packing list and configuration;

Communication with users must be adequate. Understand the user's operation process, the operations performed when the fault occurs, and the level of the user's use of the computer.

The first thing to pay attention to in maintenance is to observe, observe, observe again

Observation Content

1). Surroundings

Power supply environment, other high-power electrical appliances, electricity and magnetic field conditions, machine layout, network hardware environment, temperature and humidity, and cleanliness of the environment; whether the table on which the computer is placed is stable. Whether the peripheral equipment has abnormal phenomena such as deformation, discoloration, and odor;

2). Hardware environment

Cleanliness, temperature and humidity in the chassis, jumper setting, color, shape, smell, etc. on components, whether the connection between components or equipment is correct; whether there are errors or misconnections, missing/broken pins, etc.; user-installed All other hardware facilities that may be related to the operation of the machine, such as other equipment connected to the machine.

3). Software environment

• What kind of software is loaded in the system, and whether there is conflict or mismatch between them and other software and hardware.

• In addition to the standard software and settings, it is necessary to observe whether the drivers and patches of the device, motherboard and system are installed and suitable; whether the fault to be handled is a recognized bug or compatibility problem in the industry; other applications and configurations installed by the user is it suitable.

4). Observations during power-up

The temperature of the components, odor, whether there is smoke, etc.; whether the system time is correct.

5). Observation when disassembling parts

Have a good habit of recording the original installation status of components, and carefully observe the shape, color, and original installation status of components on the components. 

6). Observe user operations

Observe the user's operation process and habits, and whether they meet the requirements.

Before maintenance, if there is a lot of dust, or it is suspected to be caused by dust, dust should be removed first.

For applications or devices that you are not familiar with, you should carefully read the user manual or other related documents before you can operate them.

• Usually, pay more attention to accumulating your own experience and improving the maintenance level through technical data and the experience of other engineers.

• The maintenance engineer is prohibited from installing the ground wire for the user. If the user wants to install the ground wire, please contact the official electrician to install it.

• If you want to judge the fault through the comparison method and the replacement method, you should first obtain the consent of the user.

• In the process of making maintenance judgment, if it may affect the data stored by the user, it must be backed up or protected.
