The cause of the computer crash is

The crash is something that the operator is troubled with. The performance when the crash is mostly "blue screen", the system can not be started, the screen "freeze", no response, the mouse, keyboard can not be input, the software runs abnormally interrupted. Although there are many reasons for the crash, but the change is not separated from the situation, the reason can never be separated from both hardware and software.

Deadlock caused by hardware

[Poor heat dissipation]

The display, power supply and CPU generate a lot of heat during operation, so it is very important to maintain good ventilation. If the monitor overheats, it will cause color, image distortion or even shorten the life of the monitor. Too long working hours can also cause the computer or computer to freeze due to poor heat dissipation from the power supply or display. The heat dissipation of the CPU is an important issue related to the stability of the computer operation, and it is also the "hardest disaster area" in which the heat failure occurs.

[Improperly moved]

A large vibration during the movement of the computer often causes the internal components of the machine to loosen, resulting in poor contact and causing the computer to freeze, so avoid severe vibration when moving the computer. .

[Dust killer]

Too much dust in the machine can also cause a crash. If the floppy drive head or the optical drive laser head is contaminated with too much dust, it will cause reading and writing errors, which will cause the computer to crash.

[Device mismatch]

If the main frequency of the motherboard and the CPU frequency do not match, the old motherboard will set the FSB too high when overclocking, and may not guarantee the stability of the operation. Cause frequent crashes.

[Software and hardware are not compatible]

Three-dimensional software and some special software may not be able to start or even install properly on some microcomputers. There may be problems with software and hardware compatibility.

[Memory Bar Fault]

Mainly due to loose memory, virtual solder or memory chip itself. The memory module contact fault should be eliminated according to the specific situation. If there is a problem with the quality of the memory module, the memory needs to be replaced to solve the problem.

[Hard Disk Failure]

Mainly due to aging of the hard disk or bad sectors and bad sectors due to improper use. This makes it easy for the machine to crash when it is running. Special tool software can be used for troubleshooting. If the damage is serious, the hard disk can only be replaced. In addition, for motherboards that do not support UDMA 66/100, you should pay attention to the setting of the hard disk operation mode in CMOS.

[CPU overclocking]

Overclocking increases the operating frequency of the CPU and may also make its performance unstable. The reason is that the speed of CPU accessing data in memory is faster than the speed of data exchange between memory and hard disk. Overclocking makes this contradiction more prominent, which aggravates the situation where the required data cannot be found in memory or virtual memory. This will result in "Exception Error". The solution is of course simpler, that is, let the CPU return to the normal frequency.

[Hardware Resource Conflict]

An error occurred due to a conflict between the settings of the sound card or the display card. In addition, the interruption of other devices, DMA or port conflicts, may cause a few drivers to generate an exception, resulting in a crash. The solution is to start with "Safe Mode" and make appropriate adjustments in the "Control Panel" & rdquo; → & ldquo; System & rdquo; & Rar; & ldquo; Equipment Management & rdquo; For situations where an exception error is generated in the driver, the registry can be modified. Select “Run”, type “REGEDIT”, enter the Registry Editor, and find and delete all the “primary keys” associated with the driver prefix string through the “Find” function under the menu. Key value & rdquo;, restart.

[Insufficient memory capacity]

The larger the memory capacity, the better, it should be no less than 0.5~1% of the hard disk capacity. If there is such a problem, it should be replaced with the largest possible capacity. RAM.

[Inferior Parts]

A small number of unscrupulous traders use poor quality boards, memory, and even sell counterfeit motherboards and Remark CPUs and memory when assembling compatible machines to customers. Such a machine is very unstable at runtime, and it is inevitable that a crash will occur. Therefore, users should be vigilant when purchasing, and can use some newer tools to test the computer, continuous test (such as 72 hours), and strive for the longest warranty time.

Deadlock caused by software

[Virus infection]

Viruses can cause computer productivity to drop dramatically, causing frequent crashes. At this time, we need to use anti-virus software such as KV300, Kingsoft Internet Security, Rising, etc. to conduct comprehensive drug detection and anti-virus, and to regularly upgrade anti-virus software.

[Incorrect CMOS settings]

This fault phenomenon is very common, such as hard disk parameter settings, mode settings, improper memory parameter settings, resulting in the computer can not start. If the ECC-free memory is set to have the ECC function, it will crash due to a memory error.

[Error deletion of system files]

Because Windows 9x needs to have Command.com, Io.sys, Msdos.sys and other files, if these files are damaged or deleted accidentally, even The correct hardware settings in CMOS will not help. Solution: Start the computer with the boot disk of the same version of the operating system, and then type “SYS C:” to re-transmit the system file.

[Initialization file is corrupted]

Since Windows 9x needs to read System.ini, Win.ini and registry files, if there are Config.sys, Autoexec.bat files, The files will also be read. As long as there is an error message in these files, it may crash, especially the four files System.ini, Win.ini, User.dat, and System.dat are especially important.

[Dynamic Link Library File (DLL) Lost]

There is also a class of files in the Windows operating system that are also very important. This is the dynamic link library file with the extension DLL. In nature, it is a shared class file, that is, a DLL file may have multiple software that needs to be called at runtime. If we delete an application, the anti-installer of the software will record the files it has installed and prepare to delete them one by one. At this time, it is easy to delete the dynamic link library files and also be used by others. In the case of software, if the missing link library file is a more important core link file, then the system will crash or even crash. We can use tool software such as "Super Rabbit" to delete the useless DLL files, which will avoid accidental deletion.

[There is too little free space on the hard disk or too much fragmentation]

If there is too little free space on the hard disk, some applications need a lot of memory to run, so virtual memory is needed, and virtual memory is needed. It is provided by the hard disk, so the hard disk must have enough free space to meet the virtual memory needs. At the same time, the user has to develop a good habit of regularly arranging the hard disk and clearing the junk files in the hard disk.

[BIOS upgrade failed]

The BIOS should be backed up to prevent accidents, but if your system needs to upgrade the BIOS, it is best to determine if you are using the BIOS version before upgrading. Your PC matches. If the BIOS is not upgraded properly or there is an unexpected power outage during the upgrade, your system may not boot. So be sure to figure out the BIOS model before upgrading the BIOS. If the BIOS upgrade tool you are using can back up the current BIOS, please copy the previous BIOS to disk. Also see if the system supports BIOS recovery and know how to recover.
