Daily maintenance of desktop computer
Turn the machine on and off normally.
When turning on the computer, first turn on the peripheral devices connected to the computer, such as printers, scanners, monitors, etc. , and then turn on the host.
When shutting down, close all applications, and then use the Windows shutdown program to shut down normally. Don't turn it off forcibly, and don't suddenly cut off the power. When the host computer is working normally, if it suddenly loses power, it is likely to damage the hardware, especially the hard disk, because the hardware is reading and writing.
Clean the inside of the cupboard every six months.
Because heat dissipation needs to suck air from the outside to the inside of the chassis, after half a year of use, the interior of the chassis will generally be covered with a layer of dust. If there is too much dust, it will affect the heat dissipation effect of heating devices, and more seriously, it will lead to short circuit of components and burn out devices.
Therefore, it is necessary for us to learn how to open the chassis correctly for computer dust removal. If you are not sure, you can ask a professional to clean it. If it is a brand-name machine, confirm whether opening the chassis will affect the warranty.
Pay attention to computer environment.
The environment where computers are used should not be too wet and dry, the temperature should not be too high or too low, and the air should be clean and not shaken.
The ideal working temperature of the computer is 10℃-30℃ and the humidity is 30%-80%. Too high or too low will affect the life, efficiency and even safety of the computer.
Dust in the air enters the computer, which will affect the heat dissipation of the chassis and damage the equipment for a long time.
When the computer is working, it is forbidden to shake it to avoid damaging the equipment. After the computer is turned off, try to avoid vibration and prevent virtual connection or short circuit at the connection.
In addition, pay attention to the correct direction of the chassis, and do not pile up heavy objects. There should be enough space around the chassis and monitor for heat dissipation, and the connecting wires should be arranged neatly and tied together.
When it is not used for a long time, it should be turned on regularly.
If you don't use the computer for a long time, it's best to turn it on for more than half an hour every 1 month to dispel the moisture inside the chassis.
Or wrap the box in a cardboard box and put a few bags of desiccant inside to prevent the inside from getting wet.
Slimming the system forever.
When the computer is used for a long time, a large number of temporary files will be generated in the system folder because of surfing the Internet or installing or uninstalling. If it is not cleaned in time, it may slow down the execution speed of the system and increase the consumption of memory and hard disk. Temporary files are also often favored by hackers. Therefore, we should always clean up junk files and delete some uncommon software.
It is recommended to use Baidu Guardian to clean the computer, because it is light, fast, intelligent and pure, and it is always free, and it does not harass users, intimidate users or peek at their privacy. As shown below, it is very convenient to use "one-click cleaning" and delete it with one click after scanning.
Install system update patches in time to keep the software and drivers up to date.
Vulnerabilities in the operating system are constantly exposed, and hackers are constantly helping to invade other people's computers, so Windows will release system patches from time to time to fix these vulnerabilities. If your computer does not install these patches in time, it is likely to be the target of hacker attacks. It is still recommended to use "Baidu Guardian" to fix the vulnerability, as shown below. Click "Repair Now" and wait for the repair to be completed before restarting, which is very convenient.
In addition, there may be loopholes in various software and drivers installed on the computer. It is best to keep the software updated to the latest version, on the one hand, it can fix the loopholes, on the other hand, it can experience a better experience brought by the latest version of the software.
Antivirus regularly and keep the virus database updated.
Frequently surfing the Internet and using USB will inevitably plant viruses, large and small, on the computer, so it is very important to develop the habit of regular antivirus. And keep the virus database updated to kill the latest virus or virus variant.
Baidu antivirus is recommended here, because it is light, free, clean, does not harass users, does not peep into privacy, has active defense, real-time monitoring, and independently kills three guarantees. The usage method is very simple, as shown below, just click "Lightning Antivirus".
Don't open suspicious files or visit suspicious websites.
Don't easily open files that strangers can send, which will make you unconsciously infected with the virus.
Never visit pornographic, violent and reactionary websites, most of which have Trojans.
Be especially careful when you receive e-mail. It's best not to open strangers' mail.
When Baidu searches web pages, it's best not to open the website marked "risk" at the back of the website.
Do not install incompatible software and drivers.
At present, there are many operating system versions on the market, and the compatibility of various software/drivers with different system versions is not satisfactory. The problems of computer blue screen, screen display and downtime are all related to Dachuan's installation of incompatible software and drivers. For example, WindowsXP drivers should not be used on Windows7. Before installation, you need to confirm the applicable operating system version.
Try to choose a driver that has been digitally certified by Microsoft and install the officially released genuine software.
