Analysis of the causes of computer frequent crash

A crash
caused by a hardware cause




"Bad heat" displays, power supplies, and CPUs are very hot in the 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."





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





"Dust Killer" machine in the dust too much can cause a panic failure. such as floppy disk head or optical drive laser head contaminated with too much dust, will lead to read and write errors, serious will cause computer crashes.





"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.





"Software and hardware is incompatible" three-dimensional software and some special software, may be in some microcomputers can not start or even install, which may have hardware and software compatibility problems.





"Memory stripe Failure" is mainly due to loose memory, virtual welding or the quality of the memory chip itself. 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.


"Hard disk failure" is mainly due to hard disk aging or improper use caused bad, bad sector. This makes it easy to panic when the machine is running. You can use special tool software for troubleshooting, such as serious damage can only replace the hard drive. In addition, for motherboards that do not support UDMA 66/100, you should pay attention to the setting of the operating mode of the CMOS hard disk.





"CPU overclocking" overclocking improves 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." Of course, the solution is also simpler, is to let the CPU back to the normal frequency.

a "Hardware resource conflict" is caused by a conflicting sound card or display card setting that causes an unexpected error. In addition, interruptions of other devices, DMA, or port conflicts may cause a few drivers to be abnormal and panic. The solution is to start in "Safe mode" and make appropriate adjustments in "control Panel" → "System" → "Equipment management". You can modify the registry for situations where an unexpected error occurs in the driver. Select "Run", type "REGEDIT", enter Registry Editor, and, through the "Find" function under the menu, locate and remove all "primary keys" and "key values" associated with the driver prefix string and reboot.





"Memory capacity is not enough" the larger the memory capacity, should not be less than the hard disk capacity of the 0.5~1%, such as the problem, it should be replaced with the largest size of the memory.





"inferior Parts" a small number of unscrupulous businessmen to the customer assembly compatible machine, 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, users should be vigilant when purchasing, and can use some newer tools software testing computer, long time continuous test machine (such as 72 hours), as well as to strive for the long warranty time.


the crash
caused by software cause




"Virus infection" virus can make the computer work efficiency drop dramatically, cause frequent panic. At this time, we need anti-virus software such as KV300, Jinshan poison PA, rising and so on to carry out a comprehensive search virus, anti-virus, and do regularly upgrade anti-virus software.





"CMOS set improperly" this fault phenomenon is very common, such as hard disk parameter settings, mode settings, memory parameters set incorrectly so that 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.





"Incorrect deletion of system files" because Windows 9x startup requires files such as Command.com, Io.sys, Msdos.sys, and if the files are corrupted or mistakenly deleted, even a variety of hardware settings in the CMOS will be ineffective. Workaround: Start the computer with the boot disk of the same version of the operating system, and then type "SYS C:" To transfer the system files again.





"Initialization file corrupted" because Windows 9x startup requires reading System.ini, Win.ini, and registry files, these two files are also read if there are Config.sys, Autoexec.bat files. The four files, especially System.ini, Win.ini, User.dat, System.dat, are particularly important as long as there are error messages in these files.
