What about the computer crash?

The computer has entered our life, and our life is closely related to the feeling has been inseparable from the computer and the network, for some of the computer malfunctions, today small knitting here to recommend some computer crash-related articles, welcome everyone to watch the reference, want to learn more, please continue to pay attention to learning.

Computer crashes are something that bothers us. The performance of the crash is "blue screen", unable to start the system, the frame no response, the cursor can not be moved, the keyboard can not be entered, the software operation abnormal interruption. Although the cause of the crash is manifold, but same, the reason can never be separated from the hardware and software two aspects.

1. The crash caused by the hardware cause

(1) Bad heat dissipation

Monitors, power supplies, and CPUs are very hot at work, so it is important to maintain good ventilation, if the monitor overheating will result in color, image distortion and even shorten the display life.

Too long working hours can also cause power or monitor heat dissipation caused by computer crashes. The cooling of the CPU is related to the stability of the computer operation is an important problem, but also the heat failure occurred in the "hardest hit."

　(2) Improper movement

In the process of computer movement by a large vibration will often make the machine internal devices loose, resulting in poor contact, causing computer crashes, customers should avoid violent vibration when mobile computers.

(3) Dust

Too much dust in the machine can cause a crash. If the optical drive laser head contaminated with too much dust, will lead to read and write errors, serious will cause computer crashes.

(4) Device mismatch

such as motherboard frequency and CPU frequency mismatch, the old motherboard overclocking will FSB set too high, may not guarantee the stability of the operation, resulting in frequent panic.

(5) Incompatible hardware and software

Three-dimensional software and some special software, may be on some computers can not start or even install, which may have hardware and software compatibility problems.

(6) Memory bar failure

Mainly is the memory strip loose, the virtual welding or the memory chip itself quality is caused. should be in accordance with the circumstances of the memory strip contact failure, if there is a problem with the quality of memory, you need to replace the memory to solve the problem.

(7) Hard drive failure

Mainly hard disk aging or due to improper use caused bad, bad sector. This makes it easy to panic when the computer is running. You can use special tool software for troubleshooting, such as serious damage can only replace the hard drive. In addition to the motherboard that does not support udma66/100, attention should be paid to the setting of the operating mode of the hard disk in CMOS.

(8) CPU overclocking

Overclocking increases the CPU's working frequency, and may also make its performance unstable. The reason, the CPU in memory access to data faster than the speed of memory and hard disk exchange data, overclocking makes this contradiction more prominent, exacerbated in memory or virtual memory can not find the required data, this will appear "abnormal error." The solution is to get the CPU back on the normal frequency.

(9) Hardware resource conflict

An unexpected error has occurred due to a conflict in the sound card or video card settings. In addition, interruptions to other devices, DMA, or port conflicts may also cause a few drivers to cause an exception and panic. The workaround is to start in safe mode and make appropriate adjustments in Control Panel/system/Device Manager. You can modify the registry if the child generates an abnormal error in the driver. Select "Run", type "reged 丨 T", go to Registry Editor, and, through the "Find" function under the menu, locate and remove the "? Primary key" and "key values" for the driver prefix string. Reboot.

(10) Insufficient memory capacity

The larger the memory, the better, should not be hard disk capacity of 0.5 ~ 1%, if this problem arises, you should change the size of the memory as large as possible.

(11) Inferior parts

A small number of unscrupulous businessmen in the assembly of compatible machines to customers, the use of poor quality of the board, memory, and some even sell fake motherboards and remark CPU, memory, such a machine in operation is very unstable, the crash is inevitable. Therefore, we should be vigilant when purchasing, you can use some newer tools software testing computer, long time continuous test machine (such as 72 hours), as well as to strive for as long as possible warranty time.

　2. The crash caused by the software cause

(1) Virus infection

Viruses can cause a sharp drop in computer productivity, causing frequent crashes. At this time, we need anti-virus software such as KV, Jinshan poison PA, rising and so on to carry out comprehensive search, anti-virus, and do regularly upgrade anti-virus software virus library.

　(2) Improper CMOS setup

This fault phenomenon is very common, such as hard disk parameter settings, mode settings, memory parameters set incorrectly, which causes the computer can not start. If the ECC-free memory is set to have ECC capabilities, it can cause a panic due to memory errors.

(3) Error removal of system files because Windows startup needs to have Command.com, Lo.sys, Msdos.sys and other files, if these files are damaged or mistakenly deleted, even in the CMOS hardware settings are correct and no child. Workaround: Start the computer using the boot disk of the same version of the operating system, and then type "SYS C:" To transfer the system files again.

　(4) Initialization file corrupted

Because Windows startup requires reading System.ini, Win.ini, and registry files, these two files are also read if there are Config.sys, Autoexec.bat files. As long as there are error messages in these files there can be panic, especially System.ini, Win.ink User.dat, System.dat these four files are particularly important.

(5) The loss of dynamic link library files (DLLs) in the Windows operating system is also important for a class of files, this is the dynamic-link library file with the extension DLL, which in nature belongs to the shared file, that is, a DLL file may have multiple software that needs to be invoked at run time. If we delete an application, the software's anti-Setup program records the files he has installed and is prepared to delete them. At this time it is easy to delete the dynamic link library files will also be used by other software, if the missing link library files are more important core link files, Then the system will crash, or even crash. We can use tool software such as "Super Bunny" to delete useless DLL files, this will avoid accidental deletion.

(6) Too little space on the hard disk or too much fragmentation

If there is too little space left on the hard disk, and some applications require a large amount of memory, which requires virtual memory, virtual memory is provided by the hard disk, so the hard disk has enough space to meet the needs of virtual memory. At the same time, users have to develop a regular hard drive, cleaning up the garbage files in good habits.

(7) BIOS upgrade failed

BIOS safekeeping should be backed up, but if the system needs to

BIOS upgrade, it is best to determine if the BIOS version we are using is compatible with the computer version. If the BIOS upgrade is incorrect or an unexpected power outage occurs during the upgrade process, the system may not boot. So be sure to figure out the BIOS model before you upgrade the BIOS. If the BIOS upgrade tool you are using can be used for the current b| OS for backup, please copy the previous BIOS to the disk. Also see if the system supports BIOS recovery and how to recover.

(8) Improper software upgrade

Most people may think that software upgrades are not problematic,

In fact, some of the components that are shared during the upgrade are also upgraded, but other programs may not support upgraded components to cause various problems.

　　(9) Misuse of beta software

It is best to use the beta version of the software sparingly, because the test software usually comes with bugs or is not stable enough in some way, it will cause data loss due to the program error, panic or the system can not start.

(10) Illegal uninstall software

Do not delete the software installation directory directly, if deleted directly, the registry and Windows directory will have a lot of garbage, over time, the system will also become unstable and cause panic.

(11) Use of pirated software

Because these software may conceal the virus, once executes, will automatically modify our system, causes the system to appear freezes in the operation.

(12) Application software is not compatible this situation is common

(13) Too many programs to start

Causes the system resources to be exhausted, causes the data which the individual program needs to be unable to find in the memory or the virtual memory, also can appear the unusual error.

(14) Illegal operation

Illegally opening or releasing programs with illegal formatting or parameters can also cause the computer to crash. Be careful to keep the correct format and related parameters in mind, and not open and release unfamiliar programs at will.
