Many times our computers often get stuck and crash. What happened? Then I'll tell you why the computer is often stuck. I hope I can help you! Cause analysis and solution of computer often stuck and crashed due to hardware reasons 1. Poor heat dissipation: monitor, power supply and CPU generate a lot of heat during work, so it is very important to keep good ventilation. If the monitor is overheated, it will lead to color and image distortion and even shorten the life of the monitor. Working too long will also lead to poor heat dissipation of power supply or monitor, leading to computer crash. The heat dissipation of CPU is an important issue related to the stability of computer operation, and it is also the "hardest hit" where heat dissipation failures occur. 2. Improper movement: When the computer is moving, the huge vibration will often loosen the internal devices of the machine, leading to poor contact and computer crash. Therefore, violent vibration should be avoided when moving the computer. Third, the dust killer: too much dust in the machine will also lead to a crash. If the floppy disk drive head or the laser head of the CD-ROM drive is contaminated with too much dust, it will lead to reading and writing errors, which will seriously cause the computer to crash. 4. Equipment mismatch: If the main frequency of the motherboard does not match the main frequency of the CPU, the external frequency will be set too high when the old motherboard overclocks, which may not guarantee the stability of operation, resulting in frequent crashes. 5. Incompatibility between software and hardware: 3D software and some special software may not be started or even installed normally on some microcomputers, and there may be problems with software and hardware compatibility. 6. Memory failure: mainly due to loose memory, virtual soldering or the quality problem of the memory stick itself. The contact fault of memory stick should be eliminated according to the specific situation. If there is a problem with the quality of the memory, the memory needs to be replaced to solve the problem. When I started the machine, I only heard a long beep. It's probably a memory problem. Try another slot. If it still doesn't work, the memory may be broken. Hard disk failure: Bad tracks and sectors are mainly caused by hard disk aging or improper use. This makes it easy for the machine to crash during operation. Special tools and software can be used for troubleshooting. If the damage is serious, only the hard disk can be replaced. In addition, for motherboards that do not support UDMA 66/ 100, we should pay attention to the setting of hard disk operation mode in CMOS. 8.CPU overclocking: overclocking improves the working frequency of CPU, and may also make its performance unstable. The reason is that CPU can access data in memory faster than memory and hard disk can exchange data. Overclocking makes this contradiction more prominent, which aggravates the situation that the required data cannot be found in memory or virtual memory, thus "abnormal error" will occur. The solution, of course, is also relatively simple, that is, let the CPU return to normal frequency. Overfrequency and fire, sometimes the display is not bright, sometimes it crashes after entering the system, and in serious cases it will burn out the CPU. 9. Hardware resource conflict: It is due to the conflict between sound card and video card, resulting in abnormal error. In addition, if other devices interrupt, DMA or port conflict, a few drivers may be abnormal, leading to crash. The solution is to start in Safe Mode, in Control Panel? "System"? Make appropriate adjustments in "Equipment Management". If the driver has an abnormal error, you can modify the registry. Select "Run", type "Regedit", enter the registry editor, find and delete all the "primary keys" and "key values" related to the driver prefix string through the "find" function under the menu, and restart. X. Insufficient memory capacity: The larger the memory capacity, the better, and it should not be less than 0.5 ~ 1% of the hard disk capacity. If there is a problem in this respect, you should replace it with a memory stick with as large a capacity as possible. 1 1. Inferior parts: A few unscrupulous businessmen use inferior boards and memory when assembling compatible machines for customers, and some even sell fake motherboards and reused CPU and memory. This kind of machine is very unstable, and a collision is inevitable. Therefore, users should be vigilant when purchasing a machine. They can use some newer tools and software to test the computer and test the machine continuously for a long time (for example, 72 hours) to strive for the longest warranty time. Twelve, board, card contact is poor, loose, or the slot on the board is broken, or simply display card, memory stick and other accessories are broken, resulting in the display is not bright. Thirteen, the voltage fluctuation is too large, causing the current on the board to be large or small, sometimes damaging the hardware. Therefore, it is very important to choose a power supply that can prevent overvoltage or add a voltage regulator. 14, printers, recorders, scanners and other peripherals have been broken, but plug-and-play technology makes the system detect these devices at startup, leading to a crash. 15. If the host computer is running normally, there is also the sound of hard disk running, but the display is not bright, it may be that the display is broken, the signal line of the display may be in poor contact or broken, or the power supply of the display may not be plugged in. Sixteen, the motherboard capacitance. Sometimes we have no problem with other hardware, but we can't find any problems, but we can crash for a while, but this is infinite. You may guess that it is a system problem, but it is not. It's just that the motherboard capacitor is broken. Stuck and crash caused by software. 1. Virus infection: The virus will greatly reduce the working efficiency of the computer and lead to frequent crashes. At this time, you need to use anti-virus software such as KV300, Kingsoft Internet Security and Rising. Conduct comprehensive virus detection and anti-virus, and regularly upgrade anti-virus software. Second, improper CMOS settings: This kind of failure phenomenon is very common, such as the setting of hard disk parameters, mode parameters and memory parameters, which leads to the computer being unable to start. If the memory without ECC function is set to have ECC function, it will crash due to memory error. 3. System files are deleted by mistake: Command.com, Io.sys, Msdos.sys and other files are needed to start Windows 9X. If these files are damaged or deleted by mistake, even if the hardware settings in CMOS are correct, it will not help. Solution: Use the startup disk of the same version of the operating system to start the computer, and then type "SYS C:" to retransmit the system files. 4. Initialization file is damaged: Because Windows 9X needs to read System.ini, Win.ini and registry files, if there are Config.sys and Autoexec.bat files, they will also be read. As long as these files have error information, they may crash, especially the four files of System.ini, Win.ini, User.dat and System.dat are particularly important. 5. Loss of DLL files: Another type of files is also very important in Windows operating system, that is, DLL files with extension. These files are essentially shared files, that is, a DLL file may need to be called by multiple softwares at runtime. If we delete an application, the anti-installation program of the software will record the files it has installed and prepare to delete them one by one. At this time, the deleted dynamic link library file is easy to be used by other software at the same time. If the missing link library file is an important core link file, the system will crash or even crash. We can use tools such as "Super Rabbit" to delete useless DLL files, which will avoid accidental deletion. 6. The hard disk has too little remaining space or too many fragments: if the hard disk has too little remaining space, some applications need a lot of memory to run, which requires virtual memory, which is provided by the hard disk, so the hard disk should have enough remaining space to meet the demand of virtual memory. At the same time, users should form a good habit of regularly sorting out hard disks and removing junk files on hard disks. 7.BIOS upgrade failed: You should back up the BIOS to prevent accidents, but if your system needs to upgrade the BIOS, you'd better make sure that the BIOS version you are using is consistent with your PC before upgrading. If the BIOS upgrade is incorrect or an unexpected power failure occurs during the upgrade, your system may not start. So be sure to find 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 on the disk. At the same time, see if the system supports BIOS recovery and know how to recover. 8. Improper software upgrade: Most people may think that there will be no problem with software upgrade. In fact, some shared components will be upgraded during the upgrade process, but other programs may not support the upgraded components, resulting in various problems. 9. Abuse of beta software: It is best to use beta software less, because test software usually has some bugs or is not stable enough in some aspects. After use, there will be program errors, crashes or the system can't start. 10. Illegal software uninstallation: Do not directly delete the directory where the software is installed. If you delete it directly, there will be a lot of garbage in the registry and Windows directory. Over time, the system will become unstable, leading to a crash. 1 1. Use pirated software: Because these software may contain viruses, once executed, it will automatically modify your system, causing the system to crash during operation. 12. Defects of application software: This kind of situation is common, such as running 16-bit application software running well under DOS or Windows 3. 1 in Win 98. Win 98 is 32-bit. Although it claims to be compatible, there are many places that cannot be coordinated with 16-bit applications. There are also some cases, such as peripheral drivers that are normally used under Win 95. When the operating system is upgraded, problems may occur, causing the system to crash or fail to start normally. In this case, you should find a new version of the peripheral driver. In addition, software bugs can also lead to crashes. Thirteen, too many startup programs: this makes the system resources exhausted, so that the data needed by individual programs can not be found in memory or virtual memory, and abnormal errors will occur. 14. Illegal operation: Opening or releasing related programs with illegal format or parameters will also lead to computer crash. Please remember the correct format and related parameters, and don't open and publish unfamiliar programs at will. 15. Abnormal shutdown: Do not directly use the power button in the chassis, otherwise the system files will be damaged or lost, resulting in automatic startup or crash at runtime. For Windows 98/2000/NT and other systems, this is very important, and if it is serious, it will lead to system crash. 16. Memory conflict: Sometimes all kinds of software are running normally, but suddenly they crash inexplicably. It is very normal to run these applications after restarting. This is a false collapse phenomenon. Most of the reason is the memory resource conflict of Win 98. As we all know, application software runs in memory, and memory space can be released after closing the application software. However, due to design reasons, some applications can't completely release memory even after they are closed. When the next software needs to use this memory address, a conflict will occur. 17.
