The system appears illegal operation error solves the countermeasure

Error | resolution

First when the system prompts "illegal operation" do not immediately choose to close, but should first look at its detailed information, note which files are executed "illegal operation", and then close the dialog box, restart the computer, the trouble is not to restart the right to open just the error of the program, so it is easy to cause a number of related files are destroyed, In the worst case, the entire system will be paralyzed. If you run the program after restarting, no "illegal operation", which means that this is just an accidental memory conflict, very normal, can not be taken to heart. There are several reasons for "illegal operation".

First, software problems

1, some software authors just blindly pursue their own software to run well, in the writing program ignores the compatibility with the system and other software, so that the software in the operation to rob the system or other software occupied by the memory caused the system error. The solution is to uninstall these software and not use software that is incompatible with the system.

2, the software in the installation of the unauthorized replacement of some important system files, and it replaces the system file is likely to be lower than the original version of the system or there is a problem, so it is very easy to other programs call the system file error. The approach is to restore the recovery system file function provided in the System File Checker (System Information--> tool--> file Signature Verification application. If there is a problem with the. dll file, open the System information in attachment/System Tools, click the System File Checker command on the Tools menu, select Extract a file from the installation floppy, enter the name of the file you want to extract, click "Start", and "restore from" in the dialog box that pops up. The folder where the file you want to extract is specified in the typically, in the D:/win98 directory, you can also extract from the. cab file from the installation CD ("Find" the. dll file in that. cab folder first), and in the Save to item, select the folder where the file you want to recover is located, and click OK Extract the file and reboot the system.

3, Windows itself has a lot of deficiencies, especially in its inability to properly allocate and reclaim memory resources, which results in some software running without the corresponding address memory and "illegal operation." The solution is to upgrade the system and patch it.

Second, the hardware problem

1, "Illegal operation" and memory has a great relationship, so the quality of the memory bar should be listed as the primary suspect object. The most common of other hardware factors is overclocking, have seen several computers in overclocking after the system constantly report Explorer.exe perform "illegal operation", and when the CPU frequency down after they are back to normal, of course, overclocking not only for CPU requirements, other hardware (such as: graphics cards, hard drives, etc.) Also need to have a super ability to ensure overclocking success, once one of them will cause overclocking failure, the more prominent performance is the system constantly report "illegal operation." Solution: If the CPU overclocking, the CPU frequency down back. Check the memory strips, change the slots or use an eraser to rub the gold fingers.

2, the quality of the hardware itself can not be ignored, such as some display card quality is inferior, when you are in the system properties in the graphics card hardware acceleration to the maximum, it will inexplicably appear "illegal operation." Hardware drivers can also affect the stability of the system, have encountered because the hardware driver caused the system to report "illegal operation", for example, a computer as long as a boot system to report "illegal", after careful reading of the system given the detailed information found to be a sound card driver caused by the latest version of the driver after the problem is excluded. The workaround is to select "Last Known Good Configuration" in Safe mode or remove the video card driver if you are prompted to make an error, and try to enter the system. Other hardware can also be tried in this way. Updated driver, recommended to use the Driver Wizard 2004 or above, it can correctly identify your hardware and equipment and can automatically download the latest drivers, you do not know the hardware model can also help you do well.

Third, human factors can also lead to "illegal"

1, some friends in order to facilitate the likes of running a lot of software at the same time or let the system started with the software in the system tray to occupy a large row, who do not know this "bad" habits and practices will seriously affect the stability of the system. Although Windows is a multitasking platform, but they are not perfect in many ways, and the memory and system resources are limited, while allowing multiple programs to reside in memory not only occupy the already small amount of memory and system resources, and sometimes cause the program simultaneously calls the same address of the memory conflict occurs, The consequence is that "illegal operations" occur lightly, heavy system lock, if you encounter some bugs in the program itself, it is even more out of control; the easy way to do this is to type msconfig in the run Bar of the Start menu and remove the check in the Startup tab before the program starts with the system.
2, some friends in order to speed up the Internet browsing speed at the same time open multiple or even more than 10 browser window, but be aware that both IE and NC are large consumers of memory and CPU resources (friends can turn on the System Monitor while browsing to find out how busy the CPU is), while most friends have little memory on their computers. This is not enough for so many windows consumption, so once the memory and CPU resources exhausted, then "illegal operation" and the crash will follow;

3, some computer novice deletes the software not according to the normal method to uninstall, but directly to the software directory entire deletion, causes the software installs to put to the system directory file and the registry information is not able to delete, causes the hard disk the rubbish file to be more and more, the registry error is full, Of course, it's easy to make the system wrong. Or when the software is removed, the software is running, causing the system to delete the file error, the solution is to reinstall the software and then use Add/Remove Programs to remove the software.

4, in addition, Windows 98 itself does not achieve the best performance, so it is necessary to optimize it, because "illegal operations" is often due to improper memory allocation, so we first have to improve the memory management of Windows 98, in general, Windows automatically sets the maximum amount of memory to be used as cache space, but it is a very greedy system, sometimes even consumes all the memory as the cache, and other programs to Windows demand memory space for use, it will release a portion of memory to other programs to run , so this way is not very perfect, we'd better force it to specify the cache space to use, this can not because the cache space is too large to affect the operation of other software, specifically set to: Edit the System file System.ini, and find [Vcache] paragraph, in which add the following:

Minfilecache=xxx (XXX represents the minimum cache size to limit, in kilobytes: KB)

Maxfilecache=yyy (yyy represents the maximum cache to limit the range, in kilobytes: KB)

CHUNKSIZE=512 (this value is fixed, or you can not add this statement)

Here the MinFileCache, MaxFileCache should be set to the same number, the value of the calculation method is 25% of memory, such as your memory is 8MB, then they should be set to 2048, 16MB to 4096, 32MB to 8192. Here we take 64MB memory for example, which is set to:

[Vcache]

minfilecache=16384

maxfilecache=16384

chunksize=512

When you restart the computer after the modification, you will see a significant improvement in the system's performance. (Note: There are many other aspects of system tuning.) )

Four, caused by overheating of system and system components

Solution: Choose a good heat sink and cooling fan, fan speed to high, heat sink area to be large, heat sink material to be conducive to heat dissipation, with the heat dissipation parts of the contact area to be large.

V. Windows illegal operation the general "Illegal Operations" dialog window has two options: "Close" and "details." But the "details" inside the content most people do not understand, had to hastily closed. The following explains the "illegal operation" of the specific meaning of each detail, you should take a good look at Oh ~~~~~~~~

1. Stop error Number: 0x0000000A
Workaround: Disable or uninstall all anti-virus software, Disk Defragmenter or Backup program

6: Stop error Number: 0x00000058 If you are using an IDE device, define the IDE port on the board as a unique primary port. Check the IDE device's master/S/unique settings. Remove all IDE devices except the hard drive. If you cannot confirm how to do this, refer to the hardware documentation.

If your computer is formatted with the NTFS file system, you can restart your computer and then run the CHKDSK/F/R command on that system partition. If the system cannot be started because of an error, use the command console and run the CHKDSK/R command.

Run the chkdsk/f command to determine if the file system is corrupted. If Windows cannot run the chkdsk command, move the drive to another computer running Windows, and then run the chkdsk command on the drive from this computer.

8. Stop error Number: 0x0000007f The usual reason: unable to read the required pages of kernel data into memory from the paging file.

WORKAROUND: Use the latest version of the anti-virus software to check for viruses on your computer. If a virus is found, perform the necessary steps to clear it off the computer. Please refer to all system diagnostics provided by the manufacturer, especially memory checks.

Disable BIOS memory options, such as Cache,shadow.

11. Stop error Number: 0x00000079

Explanatory text: Mismatched-hal

The usual reason: the hardware abstraction layer does not match the kernel or machine type (typically occurs when a single processor and a multiprocessor configuration file are mixed in the same system).

Workaround: To resolve this error, you can use the command console to replace the wrong system files on your computer.

The kernel files for a single-processor system are Ntoskml.exe, and the kernel files for multiprocessor systems are Ntkrnlmp.exe, but these files should correspond to files on the installation media, and Windows2000 and, regardless of which original file is used, will be renamed Ntoskrnl.exe files 。 The HAL file also uses the name Hal.dll after installation, but there are several possible HAL files on the installation media, but the media is installed.

12. Stop error Number: 0x0000007a

Explanatory text: Kernel-data-inpage-error

The usual reason: unable to read the required pages of kernel data into memory from the paging file. (usually due to a failure on the paging file, a virus, a disk controller error, or a faulty RAM).

WORKAROUND: Use the latest version of the anti-virus software to check for viruses on your computer. If a virus is found. Then perform the necessary steps to remove him from the computer, see the degree software documentation to learn how to perform these steps.

If the computer is formatted with the NTFS file system. You can restart the computer and then run the CHKDSK/F/R command on the system partition. If the command cannot be started because of an error, use the command console and run the CHKDSK/R command.

Run all systems provided by the computer manufacturer in very end-to-end software, especially memory checking.

13. Stop error Number: 0xc000021a

Explanatory text: status-system-process-terminated

The usual reason: the user-mode subsystem, such as the Winlogon or client Server Runtime subsystem (CSRSS), is corrupted, so security is no longer guaranteed.

Workaround: Remove any newly installed hardware.

If you are unable to log in, restart your computer. Press F8 when a list of available make systems appears. On the Windows2000 Advanced Options Menu screen, select: Last Known Good configuration. Then press passing.

Run the Recovery Console and allow the system to fix any detected errors.

14. Stop error Number: 0xc0000221

Explanatory text: Status-image-checkisu7m-mismatch

The usual reason: The driver or system DLL has been corrupted.

Workaround: Run the fault console and allow the system to fix any detected errors.

If an error occurs immediately after the RAM is added to the computer, the paging file may be corrupted or the new RAM is faulty or incompatible. Remove the Pagefile.sys and return the system to its original RAM configuration.

Run all system diagnostics software provided by the computer manufacturer, especially the memory check

Vi. system infected virus or Trojan horse

Appear Explorer.exe error, serious when the machine crashes, sometimes can not "search", "run", can not restart, shutdown, CPU usage rate is often in 100% of phenomena. Other virus or Red code 3 it's possible to fall in love with you. Solution: Kill virus and update anti-virus software, use Trojan horse nemesis killing Trojan.

Seven, the resource manager cannot open

Old hint Explorer.exe error, an open IE on the wrong, uninstall 3721 try. If you are doing the server should not install it, otherwise unexpected errors waiting for you. Some netizens think that 3721 client software already has some of the nature of the virus.
