0x004a1993 0x021b0000 memory referenced by the directive This memory cannot be written

There are two reasons for this. The first hardware is that there is a problem with the memory. The second is the software, and the software went wrong. Caused by memory tightness.

If you know which software is causing it, you can reinstall the software first, and then it won't appear when you run it.

You don't have to worry about it if it's not often, just reinstall the system if it's very often.

This situation is called memory not being able to fully read and write, and in general: there are two reasons for this problem. One is the hardware, that is, the memory aspect. The second is software, which has many problems.

1.Hardware reasons.

The probability of memory problems is not large, the main aspects are: memory module damage, memory itself quality problems, and different brands of memory modules with different capacities are replaced, memory incompatibility may also occur, and heat dissipation problems should also be paid attention to, especially after overclocking.

If you use more than two types of memory, and different brands of memory modules are mixed or second-hand memory is used, and this problem occurs, you need to check whether there is a problem with the memory or is incompatible with other hardware, if not, then troubleshoot from the software side.

2.Software reasons.

Let's briefly talk about the principle: there is a place in memory called a buffer for storing data, and when the program puts data in this location, because there is not enough space, an overflow situation will occur. Here's an example:

A bucket can only hold one pound of water, and when you put two pounds of water, it will naturally overflow. The computer system is represented on the screen. This overflow problem often appears in the Windows 2000 XP system, Windows 2000 XP has very strict hardware requirements, once it encounters resource deadlock, overflow or illegal operations similar to Windows 98, the system will maintain stability, the above situation will occur.

Clean up the buffer area and you're good to go.

The memory cannot be a read problem, and the causes of the problem can be summarized as follows:

1. The driver is unstable and incompatible with the system, which is most likely to cause memory cannot be read or file protection.

2. One or more rogue software is installed on the system, which has a greater chance of IE or system crash, and file protection may also occur.

3. There is a conflict between the programs loaded by the system or the programs that are running on the system, especially some antivirus software monitoring programs.

4. There are vulnerabilities in the system itself, which makes it vulnerable to network attacks.

5. Virus problems are also the main causes of memory can not be read, file protection, error ......

6. If the memory cannot be read when playing the game, it is likely that the graphics card driver is not suitable (there are graphics cards that are not suitable for the game or the computer), or it may be that the version is not new enough or does not meet the game or graphics card driver.

7. The problem that some software itself is insufficient.

8. Overheating of computer hardware is also one of the reasons why the memory cannot be read.

9. Poor compatibility between computer memory and motherboard is also the fatal reason why the memory cannot be read!

Hopefully, the above summary will help you determine the cause of the memory cannot read issue.

Also, there is a simple workaround circulating online:

In the command line window, enter and press Enter.

code:for %1 in (%windir%\system32\*.ocx) do regsvr32 /s %1

When you're done, enter it again and press enter.

code:for %1 in (%windir%\system32\*.dll) do regsvr32 /s %1
