The "0X" instruction refers to "0x00000000" memory, which cannot be read or written, and then the application is closed.

If you ask some "experts", the answer you get is often indignation and disdain like "Windows is so unstable". In fact, this error is not necessarily caused by the instability of Windows. This paper will briefly analyze the general reasons for this error.

First, the application cannot check the memory allocation.

When a program needs a piece of memory to store data, it needs to use the "function function" provided by the operating system to apply. If the memory allocation is successful, the function will return the address of the newly opened memory area to the application, and the application can use this memory through this address. This is "dynamic memory allocation", and the memory address is also the "cursor" 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 value of 0. At this point, the return value "0" no longer represents the newly enabled cursor, but a notification sent by the system to the application, indicating that an error has occurred. As an application, you should check whether the return value is 0 after each memory application. If so, it means that there is a fault and some measures need to be taken to save it, which enhances the "robustness" of the program. If the application does not check this error, it will regard this value as an available cursor allocated to it according to "thinking inertia" and continue to use this memory in subsequent executions. The real 0-address storage area stores the most important "interrupt descriptor table" in the computer system, which is absolutely not allowed to be used by applications. In an unprotected operating system (such as DOS), writing data to this address will cause an immediate crash, while in a robust operating system, such as

Windows, etc. This operation will be immediately captured by the protection mechanism of the system, and the result is that the operating system forcibly closes the wrong application to prevent its error from expanding. At this time, the above-mentioned "write memory" error will appear, indicating that the referenced memory address is "0x00000000". There are many reasons for the failure of memory allocation, such as insufficient memory and mismatched system function versions. Therefore, this kind of allocation failure is more common after the operating system has been used for a long time, after installing a variety of applications (including virus programs installed unintentionally) and changing a large number of system parameters and system files.

Second, the application referenced an abnormal memory cursor due to its own BUG.

In applications that use dynamic allocation, it sometimes happens that the program tries to read and write a memory that should be available, but for some reason, the expected available cursor has become invalid. It may be "forgetting" to ask the operating system for allocation, or it may be that the program itself cancelled this memory at some point and "didn't pay attention". The logged-out memory is reclaimed by the system, and its access rights no longer belong to the application. Therefore, reading and writing operations will also trigger the protection mechanism of the system, and the only final result of the program that attempts to "violate the law" is to be terminated by the operation and recover all resources. The laws of the computer world are still much more effective and severe than human beings! A situation like this is a BUG in the program itself, and you can often reproduce the error in a specific operation sequence. The invalid cursor is not necessarily 0, so the memory address in the error prompt is not necessarily "0x00000000", but it can also be other random numbers. If the above error prompts often appear in the system, the following suggestions can be explained.

：

1. Check the system for Trojan virus. This program often irresponsibly modifies the system in order to control it.

Cause the operating system to be abnormal. We should strengthen our awareness of information security at ordinary times, and never be curious about executable programs with unknown sources.

2. Update the operating system, so that the installation program of the operating system can copy the correct version of the system files and correct the system parameters.

Sometimes there are bugs in the operating system itself, so pay attention to installing the officially released upgrade program.

3. Try a new version of the application.

Mode:

Replace virtual memory

Answer:

So far, yes, that is, if it doesn't happen again when the next cold weather comes, it means this is the main reason.

Append:

If you use

Ghost suggested deleting all *. The PF file is placed in the WINDOWS\PREFETCH directory, because WINDOWS needs to collect the physical address of the program again.

Some application errors.

"0x7cd64998" instruction refers to "0x 14c96730" memory. This memory cannot be "read" for this reason.

Source:

win

"Pre-reading" Technology of XP

This optimization technique has also been applied to application software. The system analyzes the previous startup of each application software, and then adds a virtual "memory image" to describe the application requirements, and stores this information in.

WINDOWSPREFETCH data folder. Once the image is established, the loading speed of the application software is greatly improved. The read-ahead data of XP stores the information of the last eight system startup or application software startup.

Postscript:

At present, this method is also a one-stop network (the code itself has been searching for this problem for a long time), and it is also a common problem. Originally, some programs happen almost every day. Turn off the software before reading it. ......

Not anymore.

the second

When running some programs, sometimes there will be a memory error prompt (the content after 0x may be different), and then close the program.

0x instruction refers to 0x memory. The memory cannot be read.

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

I wonder if you have ever seen such a fault.

Generally speaking, this phenomenon has many aspects. First, there is something wrong with the hardware, that is, the memory; second, there are many problems with the software.

Let's talk about hardware first:

Generally speaking, memory problems are unlikely. The main aspects are: the memory stick is broken, the memory quality is problematic, and there are two different brands of memory with different capacities, which is also prone to incompatibility. At the same time, we must pay attention to heat dissipation, especially after overclocking. You can use MemTest.

This software checks the memory, and it can thoroughly check the stability of the memory.

This problem occurs if you have dual memory, and different brands of memory chips are mixed or you buy second-hand memory. At this time, you should check whether there is a memory problem or it is incompatible with other hardware.

If not, troubleshoot the software.

Let's talk briefly about the principle first: there is a place in memory called buffer for storing data. If the program puts the data in one place, it will overflow because of insufficient space. For example, a bucket can only hold one catty of water. If you put two Jin of water in it, it will overflow. The system is displayed on the screen. This problem often appears on windows2000 and XP systems. Windows operating system

2000/XP requires a lot of hardware. In case of resource deadlock, overflow or Windows-like,

In illegal operation, when the system remains stable, the above situation will occur. In addition, it may also be caused by poor compatibility between hardware devices.

Let me give you an analysis from several examples:

Example 1: Open IE browser or "0x00000000" memory referenced by "0x70dcf39f" instruction will appear in a few minutes. The memory cannot be read. To terminate the program, click OK. After clicking OK, the message box "An internal error has occurred and a window you are using will be closed soon" will appear. After closing this prompt message, IE browser is also closed. Solution: Repair or upgrade IE browser and patch it at the same time. I see that there is a repair method that Win2000 is self-upgrading, that is, Win2000 is upgraded to Win2000. In fact, this method is to restore the system to the initial state. For example, if your IE is upgraded to 6.0, it will be changed to IE5.0 after the upgrade.

Example 2: In windows

Double-click the "AutoRun.exe" file in the CD under xp to display the "0x00000078" memory referenced by the "0x77f745cc" instruction. Memory cannot be

"Written", to terminate the program, click "OK", while in Windows.

98 miles is running normally. Solution: This may be a compatibility problem of the system. For winXP systems, right-click the AutoRun.exe file, properties and compatibility, select the item "Run this program in compatibility mode", and then select "Windows".

98/ me. If win2000 is patched with SP, just start, run and enter: regsvr32.

C: \ winnt c:\winnt\apppatch\slayerui.dll Right-click and the properties and compatibility options will also appear.

Example 3: RealOne

There was an error in the closing of gold. It used to be normal, but recently the "0xffffffff" memory referenced by the "0xffffffff" instruction appears every time it is closed. The memory cannot be read.

Tips. Solution: When the input method used is Microsoft Pinyin Input Method 2003 and the language bar is hidden (no problem when it is not hidden), this problem will occur when closing RealOne, so when closing RealOne.

You can solve this problem by displaying the language bar or using any other input method as the current input method.

Ex. 4: My hero, Super Jieba, can't call after surfing the Internet, and he is prompted every time.

Unable to read the memory "0xff0000 1 1" referenced by the "0x060692f6" instruction. Please press OK to terminate the program. Solution: Try to reinstall Hero Super Jieba. If it is reinstalled, you can try to download the corresponding version of the patch from official website. Not yet, so I have to try another player.

Example 5: Double-click the shortcut of a game, and the instruction "0x77f5cd0" means "0xffffffff".

Save, memory can't be "read", and prompt Client.dat program error.

Solution: Reinstall the latest driver of graphics card, and then download and install DirectX9.0.

Example 6: My friend sent me a message, and my computer got an error message: "0x00303033" memory is referenced by "0x772b548f" instruction, and cannot.

"Write", then QQ automatically went offline, then opened QQ and found more than a dozen messages sent by him. Solution: This is that the other party uses a BUG in QQ to send a special code and makes an error in QQ. Just patch or upgrade to the latest version, and you'll be fine.

solution

1 The memory stick is broken. Replace the memory stick.

Dual memory is not compatible with using the same brand of memory or using only one memory.

3 memory quality problems replace the memory stick

4 heat dissipation problem

Strengthen the heat dissipation inside the chassis

5 Memory and motherboard are not inserted correctly, or other hardware is incompatible. Reinsert the memory or replace the slot.

There is something wrong with the hardware. Replace hard disk

7 driving problems

Reinstall the driver. If it is a new system, install the motherboard driver first.

8 Software Damage Reinstall the software

9 software BUG patch or update to the latest version.

10 Software and system are incompatible.

Patch the software or try the compatibility mode of the system.

1 1 Software and software conflict. If any new software has been installed recently, try uninstalling it.

12 software has problems using other related software.

When reloading related software, such as playing a file in a certain format, there is an error, which may be a problem with the decoder of this file.

Antivirus of 13 virus problem

14 Antivirus software conflicts with the system or software.

Because antivirus software enters the underlying monitoring system, it may conflict with some software. Try uninstalling it.

15 system itself has a problem.

Sometimes the operating system itself has bugs. Pay attention to installing official updates, such as SP patches, and it is best to install them. If it doesn't work, reinstall the system or change it to another version.

[Say it again]

Check whether you have Microsoft NET installed. Add/Remove Frames from Programs in Control Panel. If it is already installed, consider uninstalling it. Of course, if you need a net. The framework is in other programs in the future, and you can reinstall it.

In addition, if you use ATI graphics card and you use SP2 patch (some ATI graphics card drivers need to be in the normal working environment of NET. Framework). In this case, you can find an ATI graphics card driver that does not need the support of NET.Framework.

If the above two methods can't completely solve the problem, you can try using IE repair software to check whether there is a virus or something.

Microsoft network. The framework should be upgraded to version 1. 1.

[One more thing]

Method 1:

Friends of Microsoft newsgroup give directions: start-run: regsvr32.

jscript.dll

Start running: regsvr32

vbscript.dll

But it doesn't solve it-but it provides a way to run and register all DLLs at the same time.

The search method is as follows:

Run the input command

Enter at the command prompt.

Used for% 1 in (%windir%\system32\*). Be regsvr32.exe/s.

% 1

If you enter this command correctly, you will see a fast scroll, otherwise ... otherwise failure will not have this effect. Wait slowly after getting into the car (1-2 minutes).

Don't open it until it is all running.

Method 2:

This is a typical problem ~ ~ ~ There are many reasons for this problem. Generally speaking, it is to patch the system for memory and change the slot for memory. [System patches only need to go to Microsoft.

Update website can be updated online]

(occasionally)

There are many reasons for this problem, so we can't simply draw a conclusion. It may be helpful to try the following:

1。 Make sure to use unmodified software (non-Chinese, cracked version)

2。 Try not to run other software when using the modified software. This is a temporary document. Maybe some software is also using temporary folders, which causes interference. )

3。 Turn off all those desktop tools and memory sorting tools (you have at least two similar tools running). "

Treatment method:

Run regedit to enter the registry,

Under the hook of HKEY _ local _ machine \ software \ Microsoft \ Windows \ CurrentVersion \ Explorer \ Shelleexecute.

, there should be only one normal key value "{aeb6717e-7e19-1d0-97ee-00c04fd91972},

Delete the others.

[My personal final solution and opinion]

I tried many methods today, and finally found that the problem was Microsoft's NET.Framework. I upgraded this software and patched it. After a short period of calm, there was a situation that "the memory could not be read". Later, inspired by the above article, I uninstalled Microsoft's NET. Frames 1.0 and 1. 1, all is well.

In addition: If you open "My Computer", "My Document" and so on, there is another possibility that your right-click menu is too bloated. At this time, just clean up the right-click menu problem and solve it.

[Test Results]

Among the above methods, the most effective and thorough method is as follows:

run quickly

Enter cmd enter at the command prompt.

Used for% 1 in (%windir%\system32\*). Be regsvr32.exe/s.

% 1

Tip If you are afraid of making mistakes, you can copy this instruction and click C: \ in the upper left corner of the command prompt box. Using the following "edit-paste" function, it is not easy to make mistakes. After the quick scrolling is completely still, don't start other programs in a hurry, wait patiently for a while, because the dll is still looking for a location. Don't do anything else until the indicator light stops flashing.
