As soon as the computer s memory is turned off, there is nothing, and once the memory is like a huma

It's like a person's short-term memory or working memory.

It's an instantaneous memory, just done.

1. Memory. Hard disks are used for long-term storage of data, and computers need to call up files and applications from the hard disk. The CPU needs to read data from the hard disk, and the speed of the CPU cache and the hard disk is too different, so the memory between the two speeds is needed to buffer, that is, the hard disk data is put into the memory, and the CPU reads from the memory.

Memory is one of the data storage devices of a computer, which is characterized by a small capacity, but a fast data transfer speed, to make up for the shortcomings of the hard disk although the capacity is large but the transfer speed is slow. In a computer, the memory is set up between the hard disk and the cache, so that the computing power of the CPU can be fully utilized, so that the high-speed computing power of the CPU will not be too slow due to the data extraction speed. Memory is a temporary storage of some files and applications that need to be viewed or manipulated for users to process, and the data in the memory will be automatically cleared due to power failure.

2. Virtual memory.

Memory plays a big role in a computer, all the programs running in the computer need to go through the memory to execute, if the execution of a large number of programs or a lot, it will cause the memory to be exhausted. In order to solve this problem, virtual memory technology is used in Windows, that is, a part of the hard disk space is used as memory, and when the memory is occupied, the computer will automatically call the hard disk to act as memory to relieve the tension of memory.

Like physical memory modules, virtual memory temporarily stores some files and applications that need to be viewed or manipulated for users to process, and the data in the virtual memory will be lost due to power failure.

1. The memory won't disappear, but the memory data may disappear!

This has something to do with the shutdown method you choose, when you select the "hibernation" option, the memory data will be stored in the hard disk, and you can read back the data from it the next time you turn it on, allowing you to return to the state you were in when you last shut down!

Hibernate is selected in the Power Management section of the Control Panel.

2. What are the characteristics of computer memory?

You just need to download the encyclopedia of memory! Because I can't simply tell you how.

The memory must be powered up to hold data. When the computer is turned off, the data in the memory is gone. Gone. You're right.

This is poisoning or may be rogue software, and the sequelae after that, the best way is to kill the virus first, and reinstall it if it doesn't work.

You see if the order of your memory modules is correct, sometimes it is easy to get the order wrong when changing memory modules, and there is an order on the memory modules.

The user's settings are saved when the device is turned off, and if there is an error, the same will happen. Start with a full test of the disk:

Right-click on the C drive icon General [Disk Cleanup] to clean up all junk (repair system files if prompted).

C Drive Properties Tool Error Check (Be sure to check the two options of error correction and bad sectors) [Start Check] Agree to restart the scan.

C Drive Properties Tools Defragmentation [Start Decluttering] Select C Drive [Defragmentation] (do not open other programs).

The system appears that the memory cannot be"read"or"written"The reasons are:

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

Or file protection.

2. The system has installed one or more rogue software, which has a greater chance of IE or system crash, and there may be file protection 3. There is a conflict before the program loaded by the system or the program that the system is running, especially some antivirus software monitoring programs.

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

5. The virus problem is also the main cause of memory failure.

read, file protection,

Error ......6. If there is a memory failure when playing the game.

read, it is very likely that the graphics card driver is not suitable (there are graphics cards that are not suitable for the game and the computer), or it is possible.

The version is not new enough or does not meet the game or graphics card driver.

7. The problem that some of the software itself is insufficient, and 8. The overheating of computer hardware also leads to the inability of memory.

One of the reasons for read.

9. The poor compatibility between the computer memory and the motherboard also causes the memory to not be read

The fatal cause!

Click Run.

Enter chkdsk

Run the correction to do it.

Or the disk doctor in the system maintenance in the optimization master to fix it.

Users of Windows have basically encountered this kind of warning box, and there are many reasons why it appears, there is a problem with the memory module, there is a problem with the system, there is a problem with the application writing, ......As long as it is not particularly frequent, there is no need to care about him, if it is particularly frequent, you can change the system, and it can generally be solved, if it doesn't work, then you have to consider your memory module.

Then your computer should be 2G memory, win7 system, right? Because I'm like this, open a browser, and then open a storm will be a little stuck, but there is still no automatic shutdown.

Here are a few suggestions for the problems you encounter:

For computer comparison card problems, it is best to install a security guard to clean up junk frequently and uninstall unnecessary software.

For the problem of your computer automatically shutting down, first disinfect the computer, if there is no problem, it is best to reinstall the system.

For the XP system, 2G memory is enough, but for the Win7 system, it is a bit stressful. Maybe a few years ago, when the win7 system was installed, the computer was not very stuck, with the continuous upgrading of various software, the function continues to increase and improve, and the memory demand for the computer will also increase. Therefore, if you want to speed up completely, it is best to ***4G memory, and it is only more than 100 to buy a refurbished one, which is enough for a few years.

Helping each other is a virtue, and if it helps you, thank you!
