First of all, when the system prompts "illegal operation", do not choose to close it immediately. Instead, you should first take a look at its details, write down which files have performed the "illegal operation", and then close the dialog box. , restart the computer, if you find it troublesome to directly open the program that just made the error without restarting, this can easily cause multiple related files to be damaged one after another, and in the worst case, the entire system will be paralyzed. If "illegal operations" no longer occur when running the program after restarting, it means that this is just an accidental memory conflict, which is very normal and should not be taken to mind. There are many reasons for "illegal operation" to occur.

1. Software issues

1. Some software producers just pursue the excellent performance of their own software and ignore the compatibility with the system and other software when writing programs. As a result, the software robs the memory occupied by the system or other software during operation, causing system errors. The solution is to uninstall these software and not use software that is incompatible with the system.

2. The software replaces some important system files without authorization during installation, and the system files it replaces are likely to be lower than the original versions in the system or have problems, which can easily cause other problems. An error occurred while the program was calling this system file. The way is to use the restore system file function provided in the system file checker to restore (System Information-->Tools-->File Signature Verification Application. If there is a problem with the .dll file, open "Accessories/System Tools" "System Information", click the "System File Checker" command in the "Tools" menu, select "Extract a file from the installation floppy disk", enter the name of the file to be extracted, click "Start", in the pop-up dialog box "Restore to Auto" "Specify the folder where the file to be extracted is located, usually in the d:/win98 directory, or you can extract it from the .cab file through the installation CD (of course you must first "find" which .cab file the .dll file is in folder); select the folder where the file to be recovered is located in the "Save to" item, click "OK" to extract the file, and then restart the system.

3. Windows itself also has many. The shortcomings are especially manifested in the fact that it cannot reasonably allocate and reclaim memory resources, which results in some software not being able to obtain the corresponding address memory and causing "illegal operations". The solution is to upgrade the system and apply patches.

2. Hardware problems

1. "Illegal operation" has a lot to do with memory, so the quality of the memory module should be listed as the primary suspect. Among other hardware factors, the most common one is overclocking. I have seen that after overclocking, the system of several computers kept reporting that Explorer.exe was performing "illegal operations". However, when the CPU frequency was lowered, they all returned to normal. Of course, overclocking not only places higher requirements on the CPU, but also other hardware (such as : graphics card, hard disk, etc.) also need to be overclockable to ensure successful overclocking. Once one of them fails, the overclocking will fail. The most prominent manifestation is that the system keeps reporting "illegal operation". Solution: If the CPU is overclocked, overclock the CPU. The frequency drops back. Check the memory module, change the slot or use an eraser to wipe the gold finger.

2. The quality of the hardware itself cannot be ignored. For example, some display cards are of poor quality. When the graphics card's hardware acceleration is turned up to the maximum in the properties, "illegal operation" will appear inexplicably. The hardware driver will also affect the stability of the system. There have been cases where the system reported "illegal operation" due to the hardware driver. For example, a computer reports "illegal" as soon as it is turned on. After carefully reading the detailed information provided by the system, it is found that the problem is caused by the driver of the sound card. The solution is to eliminate the problem after replacing it with the latest version of the driver. If you cannot enter the system, you can choose "Last Known Good Configuration" in safe mode, or delete the graphics card driver to see if you can enter the system. You can also try this method to update the driver for other hardware. It is recommended to use Driver Wizard 2004. or above, it can correctly identify your hardware and device and automatically download the latest driver. Even if you don’t know the hardware model, it can help you.

3. Human factors can also lead to "illegal".

1. For the sake of convenience, some friends like to run a lot of software at the same time or let the software started at the same time as the system occupy a large row in the system tray. Who knows this "bad" habit? and practices will seriously affect the stability of the system. Although Windows is a multi-tasking operating platform, they are not perfect in many aspects, and memory and system resources are limited. Allowing multiple programs to reside in the memory at the same time not only takes up the already limited memory and system resources, but sometimes It will also cause conflicts when programs call memory at the same address at the same time. The consequences are: at least "illegal operations" occur, and at worst the system locks up. If some programs themselves have bugs, it will be even more uncontrollable; The simple way is to type msconfig in the run bar in the start menu, and in the startup tab, uncheck the programs that do not need to be started at the same time as the system.

2. Some friends open multiple or even a dozen browsing windows at the same time in order to speed up Internet browsing. However, you must know that both IE and NC are large consumers of memory and CPU resources (friends can If you open the system monitor while browsing, you will find how busy the CPU is), and most friends do not have much memory in their computers, which is simply not enough to consume so many windows, so once the memory and CPU resources are exhausted, then "illegal Operation" and crashes followed;

3. When some computer novices delete software, they do not uninstall it according to the normal method, but directly delete the entire directory where the software is located, causing the software to be placed on the system during installation. Neither the files in the directory nor the information in the registry can be deleted, resulting in more and more junk files on the hard disk, and the registry is full of errors. Of course, this can easily lead to system errors. Or the software is running when you delete the software, causing the system to make an error in deleting files; the solution is to reinstall the software and then use Add/Remove Program to delete the software.

4. Caused by overheating of the system and its system components

Solution: Choose a good heat sink and cooling fan, the fan speed should be high, the heat sink area should be large, and the heat dissipation The sheet material should be conducive to heat dissipation, and the contact area with the heat-dissipated components should be large.

5. The system is infected with viruses or Trojans

Explorer.exe errors occur, and in severe cases, the computer crashes, and sometimes cannot "search" or "run", cannot restart, shut down, and uses up the CPU The rate is often at 100% and so on. Other viruses or Code Red 3 may have fallen in love with you. Solution: Check for viruses, update anti-virus software, and use Trojan Star to check for Trojans.

6. The resource manager cannot be opened

The old prompt is explorer.exe error, and an error is reported as soon as I open IE. Uninstall 3721 and give it a try. If you are a server, you should not install it, otherwise unexpected errors will be waiting for you. Some netizens believe that the 3721 client software already has some virus properties.
