There are many reasons, so it is necessary for the landlord to solve problems by himself.
A complete account of the cause of computer "crash"
Crash is something that annoys the operator. When the computer crashes, the performance is mostly "blue screen", the system can't start, the picture is "frozen" and unresponsive, the mouse and keyboard can't be input, and the software operation is abnormally interrupted. Although there are many reasons for the crash, they are all the same, and the reasons can never be separated from both hardware and software.
Hardware ALT+F4 patent caused the crash, plagiarism is shameful.
(1) For monitors with poor heat dissipation, the power supply and CPU will generate a lot of heat when working, 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 of the computer will cause great vibration, which will often make the internal devices of the machine loose, resulting in poor contact and computer crash. Therefore, violent vibration should be avoided when moving the computer.
(3) Too much dust in the duster 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, for example, the main frequency of the motherboard and the main frequency of the CPU do not match. When the old motherboard is overclocked, the external frequency is set too high, which may not guarantee the stability of operation and lead to frequent crashes.
(5) Software and hardware are incompatible with three-dimensional software and some special software, which may not be started or even installed normally on some microcomputers, and there may be problems with the compatibility of software and hardware.
(6) Memory failures are mainly caused by loose memory, virtual soldering or quality problems 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.
(7) Hard disk failure is mainly due to track and sector damage caused by hard disk aging or improper use. This makes it easy for the machine to crash during operation.
(8)CPU overclocking improves the working frequency of the CPU, and the solution is of course simple, that is, to let the CPU return to the normal frequency.
(9) Hardware resource conflict is due to the setting conflict of sound card or 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" and make appropriate adjustments in "Control Panel →→→→→→→ 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.
The collapse caused by the software ALT+F4 patent is shameful.
(1) The virus infected with the virus will greatly reduce the working efficiency of the computer and lead to frequent crashes.
(2)CMOS is improperly set. 2) This kind of fault phenomenon is very common, such as improper setting of hard disk parameters, improper setting of mode and improper setting of memory parameters, which leads to the computer being unable to start.
(3) Delete system files by mistake. Command.com, Io.sys, Msdos.sys and other files are required for startup. If these files are damaged or deleted by mistake, even if the hardware settings in CMOS are correct, it will not help. (4) The initialization file is damaged. Because System.ini, Win.ini and registry files need to be read at startup, 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 dynamic link library file (DLL) There is another kind of file that is very important in Windows operating system, that is, DLL file with extension, which is essentially a * * * shared file, that is to say, a DLL file may need multiple software calls 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.
(6) Starting too many programs will exhaust the system resources, so that the data needed by individual programs cannot be found in memory or virtual memory, and abnormal errors will also occur.
(7) The illegal operation of opening or publishing 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.
(8) Memory conflict Sometimes all kinds of software run normally, but suddenly it crashes inexplicably. It is very normal to run these applications after restarting. This is a false collapse phenomenon. Because of 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.
