Common reasons why the memory cannot be read or written

People who use the Windows operating system sometimes encounter such error messages: "The memory 0x00000000 referenced by the 0X instruction cannot be written", Then the application is closed. If you ask some "experts" for advice, the answer you get is often indignation and disdain such as "Windows is so unstable." In fact, this error is not necessarily caused by Windows instability. This article will briefly analyze the common causes of this error.

1. The application did not check the memory allocation failure

When the program needs a piece of memory to save data, it needs to call the "function function" provided by the operating system to apply. If the memory allocation If successful, the function will return the address of the newly opened memory area to the application program, and the application program can use this memory through this address. This is "dynamic memory allocation", and the memory address is also the "pointer" in programming.

Memory is not always available and inexhaustible, and sometimes memory allocation will fail. When the allocation fails, the system function will return a 0 value. At this time, the return value "0" no longer represents the newly enabled pointer, but a notification sent by the system to the application, informing the application that an error has occurred. As an application, you should check whether the return value is 0 after each application for memory. If it is, it means that a fault has occurred and some measures should be taken to save it. This enhances the "robustness" of the program.

If the application does not check this error, it will think that this value is a usable pointer allocated to it according to "thinking inertia", and continue to use this memory in subsequent runs. The real memory area at address 0 stores the most important "interrupt descriptor table" in the computer system, and applications are absolutely not allowed to use it. In an operating system without a protection mechanism (such as DOS), writing data to this address will cause an immediate crash. In a robust operating system, such as Windows, this operation will be immediately captured by the system's protection mechanism, and the result is The operating system forcibly closes the errant application to prevent its error from spreading. At this time, the above-mentioned "write memory" error will appear, pointing out that the referenced memory address is "0x00000000".

There are many reasons for memory allocation failure. Insufficient memory, mismatched versions of system functions, etc. may have an impact. Therefore, this kind of allocation failure is more common after the operating system has been used for a long time, after a variety of applications have been installed (including virus programs that were inadvertently "installed"), and a large number of system parameters and system files have been changed.

2. The application references an abnormal memory pointer due to its own bug

In applications that use dynamic allocation, sometimes there will be a situation like this: the program tries to read and write a block "Should be available" memory, but for some reason, the expected available pointer has expired. It may be that it "forgot" to request allocation from the operating system, or it may be that the program itself has logged off this memory at some point without "paying attention", etc. The unregistered memory is reclaimed by the system, and its access rights no longer belong to the application. Therefore, read and write operations will also trigger the system's protection mechanism. The only fate of a program that attempts to "illegal" is to be terminated by the operation and all resources will be reclaimed. The laws in the computer world are still much more effective and stricter than those of humans! Situations like this are all bugs in the program itself, and you can often reproduce the error in a specific sequence of operations. Invalid pointers are not always 0, so the memory address in the error message is not necessarily "0x00000000", but other random numbers.

If the system often has the error message mentioned, the following suggestions may be helpful:

1. Check whether there are Trojans or viruses in the system. Such programs often irresponsibly modify the system in order to control the system, causing operating system abnormalities. You should always strengthen your information security awareness and never be curious about executable programs of unknown origin.

2. Update the operating system and let the installation program of the operating system re-copy the correct version of the system files and correct the system parameters. Sometimes the operating system itself may have bugs, so be sure to install the official upgrade program.

3. Try the new version of the application.

When running some programs, sometimes a memory error message will appear, and then the program will close.

The "0x" memory referenced by the "0x" instruction. This memory cannot be "read".

The "0x" memory referenced by the "0x" instruction cannot be "written".

Have you ever experienced a similar failure? (The content after 0x may be different.)

Generally, this phenomenon occurs for several reasons. One is hardware, that is, memory problems, and the other is software, which has many problems.

Let’s talk about the hardware first:

Generally speaking, the possibility of memory problems is not high. The main aspects are: the memory module is broken, the memory quality is problematic, and Even if two different brands of memory with different capacities are mixed, it is easy to be incompatible. At the same time, you must also pay attention to heat dissipation issues, especially after overclocking. You can use the MemTest software to test the memory, which can thoroughly detect the stability of the memory.

If you have dual memory and mixed memory modules of different brands or bought second-hand memory, and this problem occurs, then you need to check whether there is a problem with the memory or other hardware. Not compatible. If not, then troubleshoot the software.

First let’s briefly talk about the principle: There is a place in the memory to store data called a buffer. When the program places data in one of the locations, overflow will occur because there is not enough space. For example: a bucket can only hold one kilogram of water. When you put two kilograms of water in, it will overflow. The system is represented on the screen. This problem often occurs on windows 2000 and the above situation. In addition, it may also be caused by poor compatibility between hardware devices.

Let me analyze it from a few examples:

Example 1: Open the IE browser or within a few minutes, the "0x00000000" memory referenced by the "0x70dcf39f" instruction will appear. This memory cannot be "read". To terminate the program, click the "OK" message box. After clicking "OK", the message box "An internal error has occurred and one of the windows you are using is about to close" appears. After closing the prompt message, IE browser The device is also turned off. Solution: Repair or upgrade the IE browser and apply a patch. One of the repair methods I have seen is Win2000 self-upgrade, that is, upgrading from Win2000 to Win2000. In fact, this method is to restore the system to its initial state. For example, if your IE is upgraded to 6.0, it will be replaced by IE5.0 after the upgrade.

Example 2: Double-click the "AutoRun.exe" file in the CD under Windows XP, and the "0x00000078" memory referenced by the "0x77f745cc" command is displayed. The memory cannot be "written". To terminate the program, please click "OK", but it runs normally in Windows 98. Solution: This may be a system compatibility issue. For winXP systems, right-click the "AutoRun.exe" file, properties, compatibility, select the "Run this program in compatibility mode" item, and select "Windows 98/Me" . If win2000 is patched with SP, just start and run, enter: regsvr32 c:\\winnt\\apppatch\\slayerui.dll. Right click, properties, and compatibility options will also appear.

Example 3: An error occurred when closing RealOne Gold. It had been used normally before, but recently the "0xffffffff" memory referenced by the "0xffffffff" command appeared every time it was closed. This memory cannot be "read".

Solution: This problem will occur when RealOne is closed when the input method used is Microsoft Pinyin Input Method 2003 and the language bar is hidden (no problem when not hidden). Therefore, the language bar can be displayed or any other input method can be displayed before closing RealOne. as the current input method to solve this problem.

Example 4: My Hero Super Jieba can no longer be played since it went online. Every time it prompts "Ox060692f6" (each change), the "Oxff000011" memory referenced by the command cannot be "read" and terminated. Please click OK to proceed. Solution: Try reinstalling Hero Super Jieba. If the problem persists after reinstalling, go to the official website to download the corresponding version of the patch and try. If it still doesn't work, I have to try another player.

Example 5: Double-click a game shortcut, the "Ox77f5cdO" command refers to the "Oxffffffff" memory, the memory cannot be "read", and a Client.dat program error is prompted. Solution: Reinstall the latest driver for the graphics card, then download and install DirectX9.0.

Example 6: A friend sent a message, and an error message appeared on my computer: the "0*00303033" memory referenced by the "0*772b548f" command cannot be "written", and then QQ Automatically logged out, and then opened QQ, and found more than a dozen messages sent by him. Solution: This is a BUG of the other party using QQ, sending special codes, and making QQ errors. As long as you apply a patch or upgrade to the latest version, it will be fine.

Through the above examples, we can see that there are many reasons for failure. Here is a list of the mentioned and possible reasons for easy reference.

Solution

1. If the memory module is broken, replace it

2. If the dual memory is incompatible, use the same brand of memory or only use one memory module

p>

3. For memory quality problems, replace the memory module

4. For heat dissipation issues, strengthen the heat dissipation inside the chassis

5. The memory and motherboard are not plugged in properly or are incompatible with other hardware Wait for the memory to be re-inserted or change the socket

6. If there is a problem with the hard disk, replace the hard disk

7. If there is a driver problem, reinstall the driver. If it is a new system, you must first install the motherboard driver

8. If the software is damaged, reinstall the software

9. If the software has BUG, ??patch it or use the latest version.

10. If the software is not compatible with the system, patch the software or try the compatibility mode of the system.

11. If there is a conflict between the software and the software, if any new software has been installed recently, uninstall it. Give it a try

12. The software needs to use other related software and if there is a problem, reinstall the related software. For example, when an error occurs when playing a file of a certain format, there may be a problem with the decoder of this file

13. Virus problem anti-virus

14. Anti-virus software conflicts with the system or software due to anti-virus software It enters the underlying monitoring system. It may conflict with some software. Try uninstalling it.

15. There are problems with the system itself. Sometimes the operating system itself will have BUGs. Pay attention to installing the official upgrade program, such as It is best to apply the SP patch. If that still doesn't work, reinstall the system or change to another version of the system.

It is common for a blue screen to appear when using Windows, and often the system is frequently reinstalled because the source of the error is not clear, which is time-consuming and laborious. The following has collected some Windows crash passwords for your reference.
