- BIOS damage countermeasures: Do I need to upgrade the BIOS to back up the BIOS system? Then it is best to determine whether the BIOS version used is compatible with the PC before upgrading. If the BIOS is incorrectly upgraded or an unexpected power failure occurs during the upgrade, the system may fail to start. Be sure to know the BIOS model before upgrading the BIOS. If the BIOS upgrade tool used can backup the current BIOS, please copy the previous BIOS to disk. At the same time, see if the system supports BIOS recovery (that is, boot block recovery) and understand how to recover (some tools such as Norton Utilities Rescue Disk can already back up the BIOS and restore it when problems occur). In case the BIOS upgrade fails, the above steps can be restored.
- Bad file management countermeasures: Start Windows "self-healing" Although hard disks have made great improvements in life span and stability, there are always problems with the files stored on them. File errors, such as file allocation unit errors (cluster loss) and cluster link interleaving (this usually occurs on multiple files using the same cluster block). Generally, program crashes and blue screens are caused by these two errors. In order to check and correct these file errors, you can run the ScanDisk program every few weeks (Windows comes with the program, you can find it in Start-Programs-Accessories-System Tools). Select the drive you want to scan and run it, and you're done in a minute or two. If time is available, you can also select the Fix errors option.

System crash hardware problem
- Computers are not furniture and require frequent maintenance. Software-induced crashes are a problem that all computers face, and even the best-performing PC hardware can't do without software supportthe so-called applications, operating systems, and drivers. But today's software is becoming more complex and larger. Here we will show you how to make the machine run more smoothly. Infrequent backup countermeasures: backup is not discussed. Do you back up your system often? No? It is necessary to proceed now! It is not difficult to back up some very important temporary files (such as working documents, financial information). If there is a problem with the system, it will save a lot of repetitive work. For small files, you can back up to a floppy disk, and for ten-megabyte documents, spreadsheets, photo collections, video files can be backed up to Zip, Jaz, CD-R or CD-RW, or backed up to a U disk removable hard disk In portable mobile storage devices such as these, current cloud technology also supports users to back up data to servers in the cloud, such as various types of network disks. If you think backup is very troublesome, then you can compare, which is more troublesome to re-create the lost things after system problems (such as the entire hard disk data loss due to a virus)?
Insufficient system crash performance
- If your computer has too many windows open, or if your window is higher than your computer's standard, it will also cause the window to "stuck."
Tracing to the root of the system crash
- Causes of software failure: There are several reasons for software failure, missing files, file version mismatches, memory conflicts, and memory exhaustion. The specific situation is different, maybe only because a specific software is running, or it may be serious, similar to A system-level failure.
- In order to avoid this kind of error, you can study the cause of each situation carefully and see how to detect and avoid it.

- VXD allows multiple applications to access the same hardware at the same time and guarantees no conflicts. DLLs are executable subroutines that are independent of the program and saved in the form of files. They are called into memory only when needed. Use memory more efficiently. When these two types of files are deleted or damaged, the devices and files that depend on them will not work properly.
- To detect a missing startup file, you can watch the screen when you start the PC. The missing file will display a "Cannot find a device file" message and the file name and location of the file. You will be asked to press the button to continue the startup process.
- The overwhelming cause of such startup error messages is the improper use of uninstall software. If there is a program that runs automatically after Windows starts, such as Norton Utilities, Nuts and Bolts, and you want to uninstall them, you should use the "Uninstall" option that comes with the program. Generally, this file is in the "Program" folder of the "Start" menu There will be options, or use the "Add / Uninstall" option in "Control Panel". If you delete this folder directly, the above error message may appear after the next startup. The reason is that Windows cannot find the corresponding file to match the startup command, and this command is actually placed in the registry when the software is first installed. This software may need to be reinstalled, maybe the missing files are not backed up, but at least you know what files are affected and where they come from.
- Renaming folders and files can also cause problems. You should decide on the name of the folder where the new file is located before the software is installed. If you delete or rename a folder or file running in the Start menu, you will get another error message. A dialog box will appear on the screen, prompting "Invalid startup program" and displaying the file name, but there is no The location of the file. If the shortcut on the desktop or the Start menu points to a deleted file and folder, you will get a similar "missing shortcut" prompt.
- Lost files may be stored in a separate file or in a folder shared by several applications from the same manufacturer, such as the folder \ SYMANTEC by Norton Utilities, Norton Antivirus, and other Symantec-produced software Share, and for \ WINDOWS \ SYSTEM, the files in it are shared by all programs. It is best to search the original CD and floppy disks and reinstall the damaged program.
System crash file version
- Most WIN 9X users will install various software into the system from time to time, including various patches for Windows such as Y2K, or upgrade from WIN 95 to WIN 98. Each of these steps requires a new copy to the system. Files or replace existing files. Whenever this happens, the problem that new software is not compatible with existing software may arise.
- system breakdown
- Because when installing new software and upgrading Windows, most of the files copied to the system are DLL files, and the failure of DLLs to "cooperate" with existing software is the main reason for most illegal operations, even if the affected programs are quickly closed. There is no extra time to save work that has not been completed.
- The basic design of WINDOWS makes the above DLL errors occur frequently. Unlike other versions, WIN 95 allows multiple files to share all files in the \ WINDOWS \ SYSTEM folder. For example, there can be multiple files using the same Whatnot.dll, but unfortunately, different versions of the same DLL file may separately support Different software, many software insist on installing its own version of Whatnot.dll instead of the previous one, but can the new version be "cooperative" with other software? If you run a program that requires the original version of the DLL, an "illegal operation" prompt will appear.
- Before installing the new software, back up the contents of the \ WINDOWS \ SYSTEM folder to reduce the chance of DLL errors. Since most DLL errors occur here, it is necessary to ensure that the DLL runs safely. Most of the new software will also observe the existing DLL when installing. If you need to replace the new one, a prompt will be given. Generally, you can keep the new version and indicate the file name to avoid problems.
- Most uninstallation software can also be used to monitor the installation. These monitoring records can ensure more accurate future uninstallation. In addition, you can also know which files have been modified. If a backup function is provided, you can save the files of the old version and the installation process Replaced file.
- WIN 98 and WIN 95 are different. It automatically backs up replaced files when upgrading WINDOWS and installing new software. If problems occur after WIN98 installation, you can use the Version Conflict Manager (VCM) to help find out which files have been changed. You can restore the original version from the backup of WIN 98, and VCM can find it from the "Start" menu, accessories, system tools or the installation CD of WIN 98. Another way to avoid illegal operations caused by DLL is not to run different versions of the same software at the same time, even if another new folder is prepared for the new version of the software, if you must use both versions at the same time, an illegal error message will appear .
System crash illegal operation
- Illegal operations will be confusing for many users. If you study carefully, you will find that the software is really malicious. Whenever illegal operation information appears, related programs and files will be displayed with the error type. If it is possible in Windows 3.1 It is a general protective fault (GPF), which is generally caused by two software using the same area of memory at the same time, but even if you know the reason, this type of error cannot be avoided. Users can study the cause of the error through the programs and files listed in the error message, because the error message does not directly indicate the actual cause. If an "unknown" message is given, the data file may be damaged. Check whether there is a backup or look Does the manufacturer have a file repair tool?

- To determine the cause of the blue screen, you need to carefully check the error message. Many blue screens occur after new software is installed, which is directly caused by the conflict between the new software and the current Windows settings. The real reason for the blue screen is not easy to figure out. The best way is to keep the error message and then use "blue screen" and the file name and "fatal exception" code to search the Microsoft site to determine the cause. Unfortunately, even if a particular piece of software is broken, the blue screen cannot determine what the problem file is. If multiple messages are displayed on the blue screen, then the first one should be searched first. Many blue screens can be solved by changing the WINDOWS settings. In most cases, you need to download and install an updated driver. Some blue screens are related to the version. You should determine the version of WINDOWS you use. Check the device management program of WIN 9X to determine this information.
System crash resource exhausted
- People often ask, since more memory can run more programs, most users are a bit vague about this limitation. Some Windows programs need to consume a variety of different resource combinations. GDI (Graphical Interface) concentrates a large number of resources. These resources are used to save menu buttons, panel objects, palettes, and so on. The second resource that accumulates more is USER (user), used to save menu and window information, the third is SYSTEM (system resources), is some general resources.
- system breakdown
- The vast majority of users want to be notified that resources are seriously occupied before an illegal operation or blue screen appears. WINDOWS comes with a resource meter (open the Start menu, select programs, accessories, system tools) can be placed on the toolbar in real time Shows the occupation of GDI, USER and some system resources.

System crash software countermeasures
- Countermeasure for deadly virus infection: People who have "download habit" in time to "vaccinate" should pay attention. Since many new stuffs are often downloaded from the Internet, after installation and operation, suddenly many important files are inexplicably "invisible" Is it? How can this be good-without him, run the latest virus scanner! Be sure to start a virus scanner when downloading files, sharing floppy disks, opening attachments in emails, and running macros. The best way to protect the "machine" from the virus is to scan every file downloaded, keep the virus scanning program running in the background at any time, and constantly update the virus database so that new viruses are not multiplied. Machine.

- Countermeasures against illegal uninstallation: Register the installed Windows programs in the system step by step, or create a log file in the Windows Uninstaller utility. This file will record some added files and modifications to the system configuration. When using "Add / Remove" in the "Control Panel" or using the uninstaller that comes with the program, Windows will delete all traces of this program in the system and modifications to the system. If you don't plan to use a program anymore, don't simply drag the folder of this program to the Recycle Bin to finish it. Instead, you must go step by step, click Start-Settings-Control Panel, then double-click the Add / Remove icon, select the installation / uninstall option, and finally double-click the file you want to delete. [1]
System crash program countermeasures
- Share the scourge countermeasures: upgrade your leisurely point Most people think that software upgrades will not be a problem. In fact, some components shared among them are also upgraded during the upgrade process, but other programs may not support the upgraded components and cause various problems.
- In another case, the upgrade covers shared module programs that other software will use. For example, if winsock.dll (a very important dynamic link library file for Internet access) is overwritten, programs using this file will not be able to access the Internet. If you plan to upgrade a piece of software, make a backup of the files processed with this version and uninstall the old version of the program, then install the new version and restore the previous backup.

System crash system countermeasures
- The crash caused by the system itself, even the simplest operations, such as shutting down the system or upgrading the BIOS, may have a certain impact on the PC and operating system. If you do not handle them properly in these processes, your PC may start abnormally or may not start at all. However, if you understand how to handle these operations properly, you can protect your PC from crashes.
- There is another general mistake here. When files are created, deleted, edited, and altered, the clusters that store those files are scattered across the hard disk. This will cause the Windows FAT file system to be very "struggling" when reading and writing these "fragmented" files. In order to fix these problems, you can run the Disk Defragmentation Tool (can be found in Start-Programs-Accessories-System Tools) every few weeks to reorganize the files on the disk so that the cluster blocks containing the files can be brought together . You can start after selecting the appropriate drive, but this process can take a long time.
- Countermeasure for abnormal shutdown and restart: It is better to use the Reset key less frequently. Please do not directly turn off the power of the PC or restart it before closing the window. Under normal circumstances, the program will open and create various files (for example, virtual memory swap files and temporary files). These files can only be saved after a normal shutdown and restart, and the files in memory can also be saved to the hard disk. in.
- However, if Aiji is already in a daze, even if you press Ctrl-Alt-Del and it is "numb", you have to press the Reset key.
- Windows disease countermeasures: upgrade and upgrade again! Although Windows can "harmonize" with most hardware and software, various bugs and vulnerabilities are inevitable, so Microsoft has launched many Windows patches to fix these errors. You can visit the Windows-related upgrade site or run Windows Update from the Start menu, so you can get various OS patches, strengthen system security, and get the latest tools (such as the latest version of Media Player and Internet Explorer). You can check for new updates every 3 to 6 months and choose useful downloads. It is a good idea to back up some important data before upgrading.
- Countermeasures against tampering with the registry: don't move if you don't understand! When installing Windows, it creates an important file to track a large amount of hardware and software installation information and many system settings. This file is the registry. When adding or deleting software or hardware, Windows will also modify the registry automatically. For most people, the contents of the registry are hard to understand, so do nt disturb it if you do nt know, otherwise Windows may fail to start.
- Countermeasures for accidental deletion of files: Sometimes it is necessary to "NO". When deleting files, the system will give a prompt. For ordinary files (such as documents, pictures, etc.), you can directly press "OK", and those more important files such as EXE, DLL files, or components of a certain program, please think carefully before deleting them. There are also some very important files located in the Windows System folder. Delete them carefully. However, Windows has a recycle bin, and if you empty it, many files will be permanently deleted. So don't empty it frequently. [1]
System crash considerations
- Before installing a new software, check its compatibility with the system;
- Before installing a new program, you need to protect the existing shared DLL file to prevent it from being overwritten by other files when installing the new file;
- When the illegal operation and blue screen occur, carefully study the prompt information and analyze the reason;
- Monitor the occupation of system resources at any time;
- Use uninstall software to remove installed programs.
