Hard disk failure in the computer failure of the proportion is also relatively large, because the traditional hard disk is a mechanical hard disk, more susceptible to vibration or bad use caused by hard disk failure, the following editor for you to summarize some common computer hard disk failure caused by computer pro
The whole computer is divided into hardware and software two parts, when the computer fails, everyone will analyze the hardware or software, the software part of the system will be roughly solved by reloading, but the hardware contains a lot of content, computer chassis, main body, hard disk, built-in memory, CPU fan and so on are included in the hardware facilit

In daily computer operations, we can't do without passwords anytime, anywhere-we need to use the CMOS password when starting the system, use the user password when entering Windows 98, and set the document password when editing Word documents ......, All of these provide necessary security protection for user data security! However, as the application scope of passwords increases, the number of forgotten passwords is also increasing (no one can guaran
10 common computer problems to solve by yourself
Sometimes, seemingly complex things can be solved in the simplest way. So, if there are problems with the Windows system, we might as well be able to run the Windows Update System update first, fix all the patches, or try to download a new driver, and the problem is likely to be solved.

This file is a driver file for Windows XP multiuser management. A backup of this file is available under the X:windowssystem32dllcache directory. Just copy this backup to X:windowssystem32 to replace the file with the virus. Make a Windows 98 Startup disk and copy the Attrib.exe file to the floppy disk, which is in the X:windowscommand direc
Many companies devote all their time and energy to hardware, but cable problems often make all these efforts futile. Cabling systems are the cheapest part of the network, but people often overlook cables, although it is one of the most common causes of network failure. In fact, recent studies have shown that 70% of network failures are related to cabling systems. The wiring system in the computer room bec
negligence. Although this problem has no major impact on functions, it is very troublesome to click the maximize button every time. After two days of exploration, we finally found that we can drag the window size to maximize the memory of Windows. Do not click the maximize button, and then click the close button. However, in Windows 98, to maximize mail memory, you must first maximize an opened email and then click "reply" to maximize the interface, windows 98 also remembers its maximum state.Q

Common fault four: random panic
Such failures are generally due to the use of several different chips of the memory, due to the different speed of each memory to produce a time difference resulting in a panic, this can be in the CMOS settings to reduce memory speed to be resolved, otherwise, only the use of the same model of memory. There is also a possible memory is not compatible wi
