Daily maintenance knowledge of computer systems (cleanup)

First, install anti-virus software. While the network brings convenience to you, it also brings you harm. When you download new software, new drivers or patches, or even download letters, the virus quietly lurks in a corner of your computer, making your system not run slower and slower, often inexplicably crashing, and more often To be serious, the CIH virus can invade the BIOS of the motherboard, causing various abnormalities in the computer, so anti-virus software is an indispensable tool for the computer system. At present, the most popular anti-virus software in the world are Dr Sdomon's Anti-Virus, McAfee's VirusScan, and Symant's Norton Antivirus. These softwares work in the same way, that is, after the system is started or after receiving the command, the whole process is scanned. The hard disk or part of the hard disk is found to be cleared immediately. They can also be automatically updated when you are online. This is very important, because the virus is constantly being updated. If the anti-virus software is not updated in time, how can you protect the computer?

Second, clean up the disk fragmentation. After the hard disk is used for a period of time, the storable space has become physically discontinuous. When you install an application, or save a large file, the data is usually divided into many pieces and stored in a discontinuous area of ​​the hard disk. The fragmentation of the hard disk is increasing, and the files are distributed more and more scattered. Then when you run a program and open a file, you will find the machine is unbearably slow. Therefore, regular disk defragmentation of the machine is required, that is, the file shards are continuously arranged in order on the disk space. After each cleanup, you will find that running large applications and opening large images or files is much faster. It is. Win9x comes with the Disk Defregment disk defragmenter, which you can find under "Start/Programs/Accessories/System Tools". It works just fine, but it's too slow. The Speed ​​Disk in Norton Suite is also a good disk defragmenter. It's not only fast (it takes only half of Disk Defagment to clean a 1GB hard drive), and it can take you Files that are often needed are placed on the front end of the disk (the speed can be greatly improved), and those frequently changing files are placed in a relatively empty position behind the hard disk to reduce fragmentation.

The third step is to remove redundant files. Whenever the hard disk space is in a hurry, you always have to delete some unwanted programs or files. When you press "Shifi+Delete', don't think that they have disappeared. In fact, there are some related connection files and unused registry keys that remain on the hard disk. You need to use anti-installation software to completely remove unwanted programs and files. Among the many anti-installers, Cyber ​​Media's Uninstaller and Quarterdeck's CleanSweep are the best. These two softwares are easy to use, fast, and completely erasable. They can check and remember where the application is stored on disk, as well as related connection files, duplicate files, and when the file is no longer in use, you can choose to delete some or all of the files, or you can delete the entire program, or Move the application completely into other systems. This feature is very useful when you upgrade your computer.

Checking

After cleaning up the drive, the next step is to check. By regularly scanning the hard disk, constantly upgrading the software, and constantly checking the status of the computer, you can prevent it from happening. The specific approach is as follows:

First, let the hard drive maintain a good state. Although the hard disk is not the heart of the computer, if it is damaged, the damage caused to you is also difficult to calculate. Especially in the BOOT area on the hard disk, the system may be awkward if it is slightly damaged. Therefore, the daily maintenance of the hard disk is indispensable, and these maintenance are mainly performed using the disk scanning tool software. The disk scan tool scans the physical surface of the disk, checks the directory structure of the file system, and tests the reliability of the disk. Usually, if it is abnormally shut down, the files on the hard disk are most likely to have cross-connect or cluster loss. If you don't fix it at this time, Windows will become unstable and the program execution will be wrong.

Second, keep updating the software. It is necessary to upgrade the software version from time to time. In general, software upgrades can fix bugs in older versions and reduce the error rate of applications or operating systems. Drivers that upgrade hardware can take full advantage of the hardware's performance to better communicate with the operating system. Through the manufacturer's website, you can always get the latest upgrade patches or drivers in time. In addition, some well-known personal homepages also provide software and driver downloads. If you upgrade your software frequently, you can use a special automatic upgrade tool, such as CyberMedia's Oil Change, which checks the entire hard drive, records the version number of the application (but can't be 100% accurate), and then works with the server. The database is compared and judged and automatically downloaded. Oil Change records changes in the version of more than 1,000 software and product changes from a number of hardware vendors in its database, such as Adobe, Diamond, HP and Microsoft. Other software, such as Catch-Upwww.manageable.com) and Versions www.versions.com, offer similar functionality to Oil Change.

Third, get an in-depth understanding of the internal structure of the PC. In the Start menu, select “Settings/Control Panel/System" to open the <quo;Device Management" tab. Here, you can view the details of each part of the hardware. For example, if you want to check the MODEM situation, if there is no question mark in front of the MODEM, it means that the device is in normal condition. Double-clicking on it will display more detailed information, including whether the configuration is appropriate. An easy way to configure the device or eliminate device conflicts is to use the Win 9x hardware conflict diagnostics. In addition, you can use special software to solve hardware problems, such as CyberMedia's First Aid 97, which is a pretty good hardware conflict resolution software. It can also improve the running speed and quality of Windows and freeze unstable programs. To prevent the entire system from crashing.

Fourth, improve the speed of the Internet. The slow Internet access is not the reason for the computer itself. It is mainly because the online people are narrow, unless you choose a faster connection method such as MODEM or ISDN. If there is no change in the connection method, it is still possible to improve the speed of the Internet by limiting the system. VitalSigns Software's Net.Medic is a dedicated software that improves Internet performance. It can diagnose all the status of network-related devices such as network connections, servers, MODEM, etc., and fully exploit the speed potential of network devices.
