System common crash reasons large inventory

As we all know, the crash is one of the most common faults in the process of using your computer, but the cause of the crash is different. Today, Xiaobian makes a simple analysis from the computer startup, operation and shutdown phases. The reasons for the common system crashes are as follows.

[Crash when shutting down the system]

The crash that occurs when you exit the operating system means when you exit the windows system or return to the dos state. The phenomenon of crashes. 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.

[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 due to software problems or hardware. The crash caused by the fault. 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.

After the boot, the computer system has no reaction: If the power is not turned on, look at the power cable is not connected, even if the power cable does not have any improvement, the fault may be a problem with the power supply, try to replace the power supply.

After the boot, the computer monitor has no reaction, and it has a long and short alarm sound and then crashes: firstly, the display is faulty, because even if the monitor is faulty, it will not cause the computer to crash. This is mostly the case. Because the display card is not inserted or loose, open the chassis and reinstall the display card, or try another slot, so that the problem can be solved.

The display shows a short display adapter information, and it is followed by a 1 long and 1 short alarm sound. Since the display adapter information appears, the display adapter is ok. This is often a memory failure. The solution is to open the chassis and reinstall the memory stick. If you still can't, try another memory stick. Of course, you must carefully check whether the expansion slot is intact, so you can definitely exclude this. malfunction.

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.

The crash caused by improper cmos setting: This fault is very much. Here are just a few common examples. If the hard disk parameters are not set properly or the mode is set incorrectly, the computer cannot be started, and the memory parameters are not set properly. If there is no ecc The function's memory is set to have the ecc function, which often causes the computer to crash due to a memory error. Many examples, the user only needs to correct the settings.

Computer crashes 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, because overclocking is more convenient and faster, but there is a limit to overclocking? It is not known, if it is overclocked and restarted during the restart of the computer, then your overclocking is too high, you need to lower some.

The accidental deletion or error of the system file caused the computer to fail to boot and crashed: because windows startup requires four files: command.com, io.sys, msdos.sys and drvspace.bin, if these files are destroyed Or if it is deleted by mistake, 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: Just fine.

The initialization file is corrupted, causing the computer to fail to boot and crashing: Windows startup needs to read system.ini, win.ini and registry files (user.dat, system.dat), if there is config The .sys and autoexec.bat files are of course also to be read. As long as there are error messages in these files, there may be a crash, especially the four files system.ini, win.ini, user.dat and system.dat are especially important. As long as there is a slight error, the system will not be able to start. For this reason, I strongly recommend that users must back up these four files. Previous12Next page Total 2 pages
