window| Solution |window When you are in front of the computer do not rush to rush yourself up to tens of thousands of words report, when you are playing with the computer game, suddenly the screen no longer any changes, you tap on the keyboard which button or keep shaking "little mouse" does not work, This is the kind of thing that makes you sweat-why does it always freeze at the critical moment? So you start to try every means to save your documents, but also keep crying in your mouth, "The damned computer, how the constant crash, there is no computer crash?" ”。
Playing computer so long, I have not met the computer not to crash, no matter my friend is "rookie" or DIY master, have undoubtedly met the situation of the crash, but the relative number of DIY experts to meet less. Now let's discuss all aspects of the crash ... In the computer failure phenomenon, the crash is a common fault, but also difficult to find the cause of one of the failures. According to the situation when the computer crash can be divided into four categories:
① boot during the crash: in the start of the computer, only hear the hard drive self-test sound and can not see the screen display, or simply in the post beep sound but the computer does not work, or in the post error prompts;
② in the start of the computer operating system panic occurs: Screen display computer self-test passed, but in the installation of the operating system, the computer appears to panic;
③ A panic occurs during the use of some applications: the computer is always running well and only crashes when executing certain applications;
④ exits the operating system when the panic occurs: is in the exit Win98 and other systems or return to the DOS state when the panic.
By the dry in the "panic" state can not use software or tools to diagnose the system, thus increasing the difficulty of troubleshooting. The general performance of the crash are: The system can not start, display a black screen, display "solidification", keyboard can not be entered, the software operation abnormal interruption. There are probably tens of thousands of reasons for the crash, but only two aspects: one is caused by computer hardware, one is the software design is not perfect or with the system and other running programs conflict. In the hardware, the culprit is recently in the computer DIY industry popular "overclocking" A-let the CPU work in the rated operating frequency of the clock, the CPU in excess of working state, there is no strange panic; second, one reason is that some hardware is overheating, or a hardware resource conflict. There are, of course, some other hardware reasons. On the software side, the crash caused by software is almost the majority of computers (except for overclocking computers). The 16-bit and 32-bit hybrid kernel mode is used in the Windows9x series, so the security is low, and the crash due to a program memory conflict is something that happens frequently. Here is a brief look at the failure of the general inspection processing methods.
First, the elimination of the system "fake" crash phenomenon
1. First of all, to eliminate the power problems caused by the "false" crash phenomenon. Should check whether the computer power is plugged in, the power outlet is contacted well, host, monitor and printer, scanner, external modem, speakers and other major external power equipment power plug is reliably plugged into the power outlets, the above parts of the power switch is in the state of open (on).
2. Check the data between the parts of the computer, control whether the connection is correct and reliable, whether there is loosening between the plugs. In particular, the host and the display of data cable bad often caused by "black screen" false panic phenomenon.
Second, the elimination of virus infection caused by the crash phenomenon
With non-toxic Clean system disk boot system, and then run kill,av95, scan, such as the latest version of anti-virus software to check the hard disk, to ensure that the computer security, to eliminate the virus caused by the crash phenomenon.
In addition, if the anti-virus caused by the crash, this is mostly because the virus destroyed the system files, applications and key data files, or anti-virus software in the elimination of viruses at the same time the normal files were mistakenly operated, the structure of the normal file damage. If you encounter such problems, you can only reload the system or software that is damaged (that is, the runtime causes the panic).
Third, the elimination of software installation, configuration problems caused by the crash phenomenon
1. If the crash occurs during the software installation process, it may be a conflict between some of the system's configuration and the software that is installed. These configurations include system BIOS settings, CONFIG. SYS and Autoexec.bat settings, WIN. INI, SYSTEM. INI settings and settings for some hardware drivers and memory-resident programs.
You can try to modify the settings above. The BIOS can take its default settings, such as load SETUP default and load BIOS default ; for Config.sys and Autoexec.bat, you can skip the system configuration file at startup and F5 by F8, and modify the configuration in Config.sys and Autoexec.bat on a step-by-step basis (especially in EMM386 about EMS, XMS configuration) to determine where the hardware is in conflict with the installer, some hardware drivers and memory-resident programs can avoid conflicts by not loading them.
2. If the software has been installed after the crash, it is a good installation of the program and the system conflict. The general practice is to restore the system before the installation of the various configuration, and then analyze the installation of new installed in the part of the use of resources and possible conflicts, step-by-Step troubleshooting reasons. Deleting a new installer is also one of the ways to resolve conflicts.
Four, according to the system startup process of the crash phenomenon to analyze
During the system startup process, there are two types of crashes:
1. Fatal panic, that is, the system self-test process has not completed the crash, the general system does not give a hint. This can be based on a list of fatal errors at post, combined with other methods to further analyze the cause of the failure.
2. Non-fatal panic, in the self-test process or after the completion of the self-test, but the system gives the voice, text and other information. Can be checked according to the non-fatal error code table at post and the error code table corresponding to the whistle sound at post. The sound of the siren in the post is the case listed in the error code table that focuses on the parts that may be faulty, but cannot ignore the inspection of the related parts, Because quite a few of the failures are not caused directly by the parts indicated by the message, they are often caused by the related part failure.
V. Elimination of panic caused by improper use and maintenance
Computer after a period of time may also because of use, maintenance improper and cause the panic, especially after a long time does not use the computer often appear this kind of trouble. There are several reasons for this:
1. Dust accumulation caused the system to panic: dust is the enemy of the computer. Too much dust attached to the surface of the CPU, chips, and fans will cause these components to dissipate heat, and the dust on the printed circuit board often leads to short circuits in damp environments. Both of these situations can cause a panic.
The concrete treatment method may use the brush to sweep the dust away, or uses the cotton swab to dip the anhydrous alcohol to clean the dust accumulation element. Be careful not to leave the hair brush and cotton swab on the circuit board and components to become a new source of panic failure.
2. Parts damp: Long time does not use the computer, will cause some components damp but not normal use. can use the low heat of hair dryer evenly to damp element "dry". Note that you must not heat the component part too long or the temperature is too high to avoid baking a bad component.
3. Board card, chip pin oxidation lead to bad contact: the board, chip out, with the eraser gently wipe the surface of the pin to remove oxides, reinsert the socket.
4. Board card, peripheral interface loosening cause panic: Carefully check the I/O slot plug is correct, the interface between the peripherals is good, cable connection is normal.
Vi. elimination of panic caused by improper system configuration
The system configuration is closely related to the computer hardware device and system BIOS, the jumper switch setting on the motherboard, and the common cause of the crash failure is:
1. Frequency Setup improper: This kind of fault mainly has CPU main frequency jumper switch set error, remark CPU caused by the BIOS setup and the actual situation does not match, overclocking use CPU, or CPU performance bad crash.
2. The memory bar parameter is set improperly: this kind of fault mainly has the memory bar setting error and the remark memory stripe causes the BIOS setup and the actual situation does not match.
Improper setting of 3.CACHE parameters: This kind of fault mainly has Chche setting error, Remarkcache caused by the BIOS settings and the actual situation does not match.
4.CMOS parameters are corrupted: Frequent modification of CMOS parameters, or damage to CMOS parameters by viruses, often leads to confusion in CMOS parameters and is difficult to recover. The CMOS parameters can be reset by using the CMOS discharge method and using the system BIOS default setting value. The CMOS discharge method can refer to the motherboard specification. If it is caused by a virus infection, after resetting the CMOS parameters, you must also antivirus the hard disk.
Eliminate the crash caused by improper hardware installation
Hardware peripherals in the installation process of negligence often lead to inexplicable panic, and this phenomenon is often used in the computer after a period of time only gradually revealed, and therefore has a certain degree of confusion.
1. Parts installation is not in place, plug loose, incorrect connection caused by the crash, the display card and i/0 slot contact is often caused by the failure of the display, such as "black Screen", memory, cache and socket plug is often caused by the operation of the program in the crash, and even the system can not start, other cards and sockets (sockets) The contact problem also often causes various freezes phenomenon. To troubleshoot these failures, simply unplug the corresponding board, chip, or remove the reinstall from the socket (socket). If you have an idle slot (socket), you can also swap the part for a slot (socket) to install to resolve the contact problem. Incorrect cable connections can sometimes cause a panic failure.
2. Improper installation causes parts deformation, damage caused by the wrong diameter, improper length of the screws often lead to damage to the parts of the installation hole, screw contact with the internal circuit of the parts caused by the panic, not specifications of the motherboard, parts or irregular installation steps often cause the chassis, motherboards, The variation of the shape of the board thus squeezing the internal components of the part leads to local short circuit and internal component damage, thus causing a baffling panic. If only the computer part appearance distortion, May through the correct installation method and the replacement conforms to the specification the component to solve, if already causes the internal component to be damaged, only then replaces the new spare parts.
Eight, the elimination of hardware quality caused by the crash phenomenon
Generally speaking, computer products are international manufacturers in accordance with the standard line production, the component of poor rate is very low. But the lure of high profits has led many illegal manufacturers to reinvent their computer-standard parts, carry out thyristor, re-marking (remark), shoddy even the scrap, defective as authentic sale, resulting in these "super level" performance of the products are not stable, the environment slightly unwell or use a little longer time will be frequent failure. In particular, the CPU, memory, motherboards and other core components and related products of poor quality, is leading to no reason to panic the main source of failure. The following parts should be examined emphatically:
1.CPU CPUs are the most frequently counterfeited parts that cause panic. The remark CPU at low temperature, short time to use all normal, but as long as in the continuous high temperature environment for a long time to use, its crash malpractice is very easy to expose. The use of Windows, 3DS and other CPU-specific requirements of software more than a simple software such as DOS to discover the problem of the CPU. If you want to confirm whether this is the case to confirm whether this failure can be referred to the manual CPU frequency jump 1 to 2 grade use, such as the 166 down to 150, 133 or 120 use. If the crash phenomenon greatly reduced or disappeared, it can be judged that there is a problem with the CPU. can also use the Exchange method, replace the same model of the normal CPU, if no longer panic can be generally concluded that the problem is CPU. Some users like to use the CPU overclocking to achieve high-speed performance, which is often caused by the computer crash reasons. Generally the CPU jump back to the original frequency can solve the crash problem.
2. Memory strips are often done with the hands and feet: Speed tag has been changed, such as: 70ns was remark as 60ns, not parity as parity memory, not EDO memory impersonating Edo memory, inferior memory to impersonate good memory strips. In the BIOS, the memory bar reads and writes time appropriately increases (for example: from 60ns to 70ns), if the crash disappears may determine is the memory strip speed problem. If it is the quality of the memory itself, only replace the new memory bar to resolve.
3. Motherboard General motherboard failure is often the first consideration but it is to the last to be determined. In addition to the flying line on the printing board, disconnection and components on the motherboard are burnt, the motherboard is extruded deformation, the main
