Computer Crash reason Daquan

The crash is something that makes the operator rather annoying. When the performance of the crash is "blue screen", unable to start the system, the screen "freeze" no response, the mouse, keyboard can not be entered, the software operation abnormal interruption. Although the cause of the crash is a lot, but same, the reason is never out of hardware and software two aspects.

Panic caused by a hardware cause

"Bad Heat"
Monitors, power supplies, and CPUs are extremely calorific at work, so it is important to maintain a good ventilation condition, and if the display is overheating, it will result in color, image distortion, and even a shortened 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 process of computer movement 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."
Too much dust in the machine can cause a crash. 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.

"Hardware and software is incompatible"
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.

"Memory Stripe 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.

"Hard Drive Failure"
Mainly hard disk aging or due to 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 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." Of course, the solution is also simpler, is to let the CPU back to the normal frequency.

"Hardware resource conflict"
is due to a conflict in the sound card or display card settings, causing an exception 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.

"Insufficient memory capacity"
The larger the memory capacity, the better, should not be less than the hard disk capacity of the 0.5~1%, such as the problem, it should be replaced as large as possible memory.

"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, 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.

Crashes caused by software causes

"Viral 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 failure phenomenon is very common, such as hard disk parameter settings, mode settings, memory parameters are set incorrectly, causing the computer to 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 so on, 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.

"Dynamic link library file (DLL) is missing"
It is also important to have a type of file in the Windows operating system, which is the DLL-extension dynamic-link library file, which is, in nature, a shared class 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 it 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.

"Hard drive left space too little or too much fragmentation"
If there is too little space left on the hard disk, because some applications need a lot of memory to run, which requires virtual memory, and virtual memory is provided by the hard disk, the hard disk will have 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.

"BIOS upgrade Failed"
You should back up your BIOS safekeeping, but if your system needs to upgrade your BIOS, it's a good idea to determine if the BIOS version you are using is compatible with your PC before upgrading. If the BIOS upgrade is incorrect or an unexpected power outage occurs during the upgrade process, your system may not boot. So be sure to figure out the BIOS model before you upgrade the BIOS. If you are using the BIOS upgrade tool to back up the current BIOS, please copy the previous BIOS to the disk. Also see if the system supports BIOS recovery and how to recover.

"Improper software Upgrades"
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.

"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.

"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.

"Use pirated Software"
Because the software may hide the virus, once executed, will automatically modify your system, so that the system in the operation of the panic.

"Flaw in application Software"
This situation is common, such as running those in Win 98 in DOS or Windows 3. 1 running good 16-bit application software. Win 98 is 32-bit, although it is known to be compatible, but there are many places that cannot be reconciled with 16-bit applications. There are also cases, such as the normal use of the peripheral driver under Win 95, when the operating system upgrade, there may be problems, so that the system crashes or does not start properly. In this case, you should find a new driver for your peripherals.

"Too many programs started"
This causes the system resources to be exhausted, so that the data required by the individual program can not be found in memory or virtual memory, there will also be an exception error.

"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.

"Unhealthy shutdown computer"
Do not directly use the power button in the chassis, otherwise the system files will be damaged or lost, causing automatic startup or running panic. For systems such as Windows 98/2000/NT, this is very important and serious, and can cause system crashes.

"Conflict in Memory"
Sometimes running a variety of software are normal, but suddenly inexplicably panic, restart after the operation of these applications is very normal, this is a false panic phenomenon. Many of the reasons for this are the conflict of memory resources for win 98. As you know, applications run in memory, and when you turn off the application, you can free up memory space. But some applications because of the design, even after the shutdown can not completely release the memory, the next software needs to use this memory address, there will be conflicts.
