Everyone knows that the crash is one of the most common faults in the process of using your computer, and the cause of the crash is confusing and elusive. In the past dos era, the cause of the crash is usually based on viruses, of course, there are other reasons, such as the application software settings, so there is a certain mode to solve the crash, specifically the first anti-virus, check the hard disk space is not Enough, then check the autoexec.bat and config.sys files for error commands. If the problem is not resolved, you can check the hardware, so that's it. But now it is different, now is the Windows era, the cause of the crash is ever-changing, so it is quite tricky to deal with. Regardless of the case, the solution to the crash is first soft and hard, and the software aspect is of course the first anti-virus, then some application software, drivers, etc., you do not forget the registry editing and some settings of cmos哟Finally, the most effective way to teach you a trick is to drop the hard drive (just kidding). The hardware is mainly the heat problem. Now the machine runs fast, of course, the heat generated is more, then use the most effective hardware troubleshooting method —— replacement method to find out the real murderer. Having said that, it is still specific to talk about the crash, from the computer startup, operation and shutdown phase of the phenomenon of crashes for a simple analysis.
[Crash during startup]
To analyze the crash of the computer at startup, you must first understand the startup sequence of the computer system to analyze whether the computer is caused by a software problem or a hardware failure. Therefore, it is necessary to briefly introduce the startup sequence of the computer system: turn on the computer power → detect the graphics card → detect the memory & rarr; execute the bios & rarr; detect other devices (cpu, hard disk, etc.) → execute the operating system (os) Initialize the file. The boot process of the operating system is more complicated. The first is to transfer the bootstrap loader program and the self-diagnosis program in the rom (read-only memory) to the ram (random memory). With the bootstrap loader running, the system files of the operating system. It will also be loaded into the ram, and then the two system files io.sys and msdos.sys will be executed. At this time, the “displaying windows98……” screen will appear on the computer display, and finally the system.ini and win.ini will be initialized. Read the registry file. At this point, if there are no problems, the computer system will be successfully started. Here is a look at the crash that occurred during this process.
The computer system does not respond after booting: If the power is not turned on, look at the power cable is not connected, even the power cable does not have any improvement, the fault may be a problem with the power supply, try to replace the power supply.
The computer monitor does not respond after booting, and it is followed by a long 2 short alarm sound. The first thing is to eliminate the display failure, because even if the display is faulty, it will not cause the computer to crash. This is mostly due to the display. The card is not inserted or loosened. Open the chassis and reinstall the display card, or try another slot. This will solve the problem.
The display shows a short display adapter information, and there is a 1 long and 1 short alarm sound after the crash: since the display adapter information appears, the display adapter is ok, this situation is often a memory failure, the solution Open the chassis and reinstall the memory module. If it doesn't work, try another memory stick. Of course, you must take a good look at the expansion slot to see if it is intact. This will definitely eliminate this fault.
The crash after the bios upgrade failed: find the computer with the same model bios motherboard, back up the bios program on this computer, use the bios refresh program to refresh it, provided that the bios can be refreshed.
Criminate caused by improper cmos setting: This fault is very much. Here are just a few common examples, such as improper hard disk parameter setting or improper mode setting, which can cause the computer to fail to start, memory parameters are not set properly, such as memory without ecc function. Set it to have the ecc function, which often causes the computer to crash due to memory errors, and so many examples, the user only needs to correct the settings.
Starting computer crash after computer overclocking: Now overclocking is a very fashionable topic for the majority of computer users. From time to time, the computer is overclocked, especially now many motherboard manufacturers will overclock in cmos, so diy Don't mention how happy you are, because overclocking is more convenient and faster, but is there a limit to overclocking? It is not known that if you overclock after restarting your computer after overclocking, then your overclocking is too high and you need to lower it.
The accidental deletion or error of the system file causes the computer to fail to boot and crashes: Since windows startup requires four files: command.com, io.sys, msdos.sys and drvspace.bin, if these files are damaged or mistaken If you delete it, even if the various hardware settings in cmos are correct, it will not help, and the system will not start. The only way to solve the problem is to start the computer with a floppy disk (of course, the system disk with the same system version), and then type sysc:.
Initialization file corruption caused the computer to fail to boot and crashed: Windows startup needs to read system.ini, win.ini and registry files (user.dat, system.dat), if there is config.sys and The autoexec.bat file is of course also to 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 important. Ding point error system will not be able to start, for which I strongly recommend that users must always back up these four files.
[The crash in the running process]
The crash at runtime refers to the crash situation in the process of using windows, that is to say, running some applications under the windows operating platform without crashing. . Some of this phenomenon is a conflict between the application and the operating system, some are bugs in the application itself, etc., the following describes the crash phenomenon in the operation.
Crashes when running certain applications: There are three possible reasons for this failure. One is that the application is infected by a virus, then the application itself has a bug, and the application and operating system are There are some conflicts between them.
The crash caused by insufficient resources: too many applications are opened during use, which consumes a lot of system resources, resulting in insufficient resources during use. Therefore, when using relatively large applications, it is best to use less. Open the software that is not related to this application.
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 given by the hard disk. So, the hard disk needs to have enough free space to meet the virtual memory requirements; and we have to develop the habit of regularly tidying up the hard disk regularly.
Some files are overwritten and cause some applications to crash. Some file overlay prompts appear when installing new applications. I suggest that you do not overwrite any files, otherwise it may cause some applications to crash. (prevention).
Some files are deleted and cause some applications to crash. When we uninstall some applications, there are often prompts for deleting certain files. If you are not particularly aware of whether the file has any relationship with other files, It is best not to delete it, otherwise it may cause some applications to run due to the lack of certain files, and even cause the entire system to crash (preventive).
The mouse and keyboard are not responding after the program runs: the application crashes after running, indicating that the application does not end normally, and it always occupies system resources, and the operating system is not clear about this situation. To end the application, only implement the mandatory means, that is, press the ctrl, alt, and del keys at the same time to end the task.
Setting the power saving function causes frequent black screen crashes on the display: generally because the energy saving time is set too short in bios, or the time set in the screen saver is too short.
Hardware overclocking causes a crash in operation: After overclocking, the computer can start, indicating that overclocking is successful, why is there a crash when running? Generally, the hardware crashes due to overheated hardware and cannot be timely dissipated. Therefore, we often have to make reasonable improvements to the heat sink while overclocking.
Hardware: Computer hardware configuration is too low, memory speed does not match (dead phenomenon: mouse can move, click no response), interrupt settings cause hardware conflicts, various drivers do not match, etc. may also cause The phenomenon of crash during operation.
[Crash when shutting down the system]
The crash that occurs when you exit the operating system refers to the crash that occurs when you exit the windows system or return to the dos state. If Windows can't be completely shut down, it will write the data in the disk buffer to the hard disk, and then enter an infinite loop. Unless the user restarts the system, the system cannot be shut down. The cause of this phenomenon may be related to the operating system settings and improper settings of some drivers. Generally, Windows will close the drivers that are being used when exiting the system or returning to the dos state. These drivers will also be used according to the current situation. The data is written back, but if the driver is not properly set up, the driver can't find the device, so it keeps searching for the device, which creates a fake crash.
In general, there are many reasons for the crash. In any case, the general method of dealing with the crash problem is to soften and harden first, that is, to consider the hardware failure after considering the application software, the focus should be on the software, specifically the application software. Look for the installation settings and some driver installation settings to find out why. Finally, look for the hardware reasons, the general hardware reasons can be managed through the device settings in the system settings or can be found in the system information of the Windows operating system accessories.
