How to deal with crashes and blue screens

Why does the blue screen crash?
What makes the operator quite worried about by the crash often makes the fruits of labor go nowhere. Crash occurs on a blue screen, and the system cannot be started. Wu reflected that the screen was "Frozen", the mouse and keyboard could not be input, and the software was interrupted abnormally. There are many causes of near-pipe crashes, but the reasons are never the same as those of hardware and software. The machines that run well now frequently present a blue face, which makes people uncomfortable. This section describes some common causes and solutions for blue screen crashes.
I. Hardware-caused crash
1. computer overheating loss: the display, power supply, and CPU are very hot at work, so maintaining good ventilation is very important. If the display is overheated, it will lead to color, image distortion or even shorten the display life. Too long working hours will also lead to poor power supply or display heat dissipation and lead to computer crashes, you may wish to give the CPU price a high-performance radiator.
2. Improper movement: the computer's internal devices are often loose due to high vibration during the computer's movement, resulting in poor contact and computer crashes. Therefore, do not shake mobile computers.
3. dust: If the components in the machine are contaminated with excessive dust particles, such as the head, leading to read and write errors, serious computer crashes or even damage to the components, so keep the air clean, if there is too much dust in the computer, it should be cleared.
4. device mismatch: If the motherboard and CPU do not match, frequent crashes may occur if the clock speed is too high or too low. In this case, you can change the corresponding hardware as needed.
5. hardware and software incompatibility: for example, when running Photoshop, AutoCAD 3D animation, and graphic design software, different hardware devices may have different effects and may cause crashes. We can select the appropriate hardware or software based on the actual situation.
6. Memory Stick failure: mainly caused by loose memory stick, virtual soldering, or memory core quality. Eliminate memory stick contact Faults Based on actual conditions. If the memory stick has quality problems, replace them.
7. Hard disk failure: it is mainly caused by the hard disk aging or improper use of the hard disk, resulting in Bad Sectors and sectors. In this way, the machine will easily crash during operation. If the circumstances are mild, you can use dedicated tools and software to remove them. If the circumstances are serious, you can only replace the hard disk.
8. CPU overclocking: The overclocking improves the CPU and also makes its performance unstable. The reason is that the speed at which the CPU accesses data in the memory (RAM) is faster than the speed at which data is exchanged between the memory and the hard disk. The overclock makes the conflict more prominent, this makes it even more difficult to find the required data in the memory or virtual memory. In this case, an "Exception error" occurs: the solution is simple, that is, to make the CPU work at the specified normal frequency.
9. hardware resource conflict: it is an exception error caused by a conflict of sound card or display card settings. In addition, interruption of other devices, DMA or port conflict may lead to exceptions in a few drivers, resulting in a crash. Solution: Start in "safe mode" and make appropriate adjustments in "Control Panel-system-device management". This can be solved in general. You can modify the registry if an exception occurs in the driver. Select "start-Run" and type "REGEDIT" to go to the Registry Editor. Click "Search" in the menu, find and delete all "primary keys" and "key values" related to the driver prefix string, and restart.
10. Insufficient memory capacity: The larger the memory capacity, the better. It should be no less than 0.5-1% of the hard disk capacity. Therefore, replace the memory as large as possible.
11. use of inferior components: when a few unscrupulous merchants assemble compatible computers for customers, they use inferior boards, memory, and some even sell fake boards and remaek cpu and memory, such a machine is unstable during operation, and it is inevitable that it will crash. Therefore, you should keep your eyes open when purchasing a machine. It is best to bring an expert adviser and test the computer with newer tool software (such as HWINFO and NORTON, continuous machine testing (for example, 72 hours) for a long time, and try to maintain the minimum warranty period.
2. software-related crashes
1. Virus Infection: viruses can cause a sharp drop in computer productivity and cause frequent crashes. At this time, we need to use anti-virus software, such as KV3000, Kingsoft drug overlord, and rising star, to comprehensively check and eliminate viruses, and regularly Upgrade anti-virus software.
2. Improper configuration of CMOS: This fault is common, such as hard disk parameter setting, mode setting, and memory parameter setting, leading to computer startup failure. If you set the memory without the ECC function to the ECC function, a memory error may cause a crash.
3. system File Deletion (or error): Command.com and Lo are required for Windows 9X startup. sys, Msdos. sys and Drvspace. bn files. If these files are damaged or deleted by mistake, it will be useless even if the various hardware settings in CMOS are correct. Solution: Use the boot disk of the same operating system to start the computer, and then type sys c: Yes.
4. Damage to the initialization file: the System. ini, Win. ini, and registry files must be read when Windows 9X is started. If the Config. sys and Autoexec. bat files exist, they will also be read. Any error message in these files may crash. In particular, System. ini, Win. ini, User. dat,
The four files System. dat are particularly important.
5. dynamic Link Library file (DLL) loss: another type of file in the Windows operating system is also very important. This is the dynamic link library file with the DLL extension, these files are shared files in nature. a dll file contains multiple software that must be called during running. When you delete some applications, the software installer records the files it has installed and prepares to delete them one by one. In this case, it is easy to delete dynamic link library files, it is also a situation where other software needs to be called during operation. A software error occurs. If the lost link library file is an important core link file, the system will crash or even crash.
6. The remaining space on the hard disk is too small or there are too many fragments: if the remaining space on the hard disk is too small, because some applications require a large amount of memory to run, virtual memory is required, the virtual memory is provided by the hard disk, so the hard disk must have enough space to meet the virtual memory requirements. At the same time, we also need to develop a good habit of regularly organizing hard disks and clearing junk files on hard disks.
7. BOOS upgrade failed: Back up the BIOS to prevent unexpected events. If your system needs to upgrade the BIOS, it is best to determine whether the BIOS version you are using matches your PC before the upgrade. If the BIOS is incorrectly upgraded or an unexpected power failure occurs during the upgrade, the system may fail to start up. Therefore, you must understand the BIOS model before upgrading the BIOS. If you use the BIOS upgrade tool to back up the current BIOS, copy the previous BIOS to the disk. It also depends on whether the system supports BIOS recovery and how to recover it.
8. Improper software upgrade: Most people think that software upgrade will not be a problem. In fact, some components shared in the upgrade process are also upgraded, but other programs may not support the upgraded components, resulting in various problems.
9. Misuse of beta software: it is best to use less test versions of software, because the testing software usually carries some buckets or is not stable enough in some aspects, after use, a program error occurs, crashes, or the system cannot start.
10. uninstall software illegally: Do not delete shared files because some shared files may be used by the system or other programs, may cause some applications to fail to start and crash, or the system may crash. Do not delete the directory where the software is installed directly. If you delete the directory directly, the Registry and the Windows directory will produce a lot of garbage. Over time, the system will run unstable and cause a crash.
11. using pirated software: it must undergo thorough virus detection and testing, because most of these software carries a large number of viruses. Once executed, your system, infected system, or application software will be automatically modified, it is a system and a crash in mind.
12. Application Software defects or incompatibility with system software: this situation is common, for example, the 16-bit applications running well in DOS or Windows 3.X in Windows 98. Windows 98 is 32-bit. Although it is known as compatible, it cannot be coordinated with 16-bit applications in many places. Microsoft will not make great effort to study what it is about to give up. Therefore, if it is not necessary, it is best not to use 16-bit application software.
13. Too many programs are started: the system resources are exhausted, and the data required by individual programs cannot be found in the memory or virtual memory. The system may encounter an exception or error. Solution: Do not start too many applications at the same time. In case of an "exception", simply restart the system.
14. Illegal operation: if the program is opened or released in an invalid format or parameter. Keep in mind the correct format and parameters, and do not open or release unfamiliar programs at will.
15. Disable the computer abnormally: do not directly use the power button of the chassis. Otherwise, system files may be damaged or lost, causing Automatic startup or crash. For systems such as ipvs 98/2000/NT, this is very important. Otherwise, it will cause serious system crash or hard disk damage.
16. Sometimes all kinds of software run normally, but suddenly it is inexplicably crashed. After restart, these applications run normally, which is called a false death. Most of the reasons are Windows 98 memory resource conflicts. As you know, the application runs in the memory, and the space can be released after the application is disabled. However, some application software cannot completely release the memory even after it is disabled due to design reasons. When the current software needs to use a memory address, there will be conflicts.
In short, Windows crashes are indeed caused by a variety of abnormal shutdown, and the solution should be targeted. Just like the computer's strange faults, their respective solutions are also different. I have explained the causes and methods of various computer crashes to help you understand what happened when the computer crashes, we adopt different solutions for only one task to make our computer work better.
