What are the manifestations of memory failure？

　　12 manifestations of memory failure.

First, boot without display

　　This kind of failure is a common phenomenon due to the memory stick, which is generally caused by poor contact between the memory stick and the motherboard memory slot (on the premise of eliminating the failure of the memory itself). Just rub the golden finger with an eraser back and forth to solve the problem (don’t clean it with alcohol, etc.), and memory damage or problems with the motherboard memory slot can also cause this kind of failure.

　　There is no display failure when the computer is turned on due to the memory module, and the host speaker will generally beep for a long time (for the AwardBios).

Second, the windows system is unstable and often produces illegal errors.

　　This kind of failure is generally caused by poor quality of memory chips or software reasons. If it is determined that it is the memory stick, there is only one way to replace it.

Third, the windows registry is often damaged for no reason, prompting users to recover.

　　Such failures are generally caused by poor quality of memory chips, which are difficult to repair, and there is only one way to replace them.

Fourth, windows often automatically enters the safe mode.

　　This kind of failure is generally caused by the incompatibility between the motherboard and the memory stick or the poor quality of the memory stick. It is common for PC133 memory to be used on some motherboards that do not support PC133 memory stick. You can try to reduce the memory reading speed in CMOS settings to see if the problem can be solved. If not, the memory stick will have to be replaced.

Five, random crash

　　This kind of fault is generally due to the use of several different chips of memory chips. Because of the different speeds of each memory chip, there is a time difference, which leads to the crash. This can be solved by reducing the memory speed in CMOS settings, otherwise, only the same type of memory can be used. Another possibility is that the memory module is incompatible with the motherboard, which is generally rare. In addition, it is also possible that the computer crashes randomly due to poor contact between the memory module and the motherboard, which is quite common.

Six, the system resources decrease after the memory increases.

　　This kind of phenomenon is generally caused by the incompatibility between the motherboard and the memory. It is common that the PC133 memory stick is used on some motherboards that do not support the PC133 memory stick. Even reinstall the system can’t solve the problem.

Seven, when windows starts, when loading the high-end memory file himem.sys, the system prompts that some addresses have problems.

　　This problem is generally caused by the damage of some chips of the memory stick, and the solution can be found in the following memory maintenance method.

Eight, when running some software, there is often a hint of insufficient memory.

　　This phenomenon is generally caused by the lack of remaining space on the system disk. You can delete some useless files and leave more space, and it is generally appropriate to keep it at around 300M m.

Nine, from the hard disk boot to install windows to detect disk space, the system prompts that memory is insufficient.

　　This kind of failure is generally due to the fact that the user added the emm386.exe file to the config.sys file, and the problem can be solved by shielding it.

　　In fact, the method of booting windows from the hard disk in DOS mode is complicated and slow. First, DOS files must be installed on the hard disk, and config.sys and autoexec.bat files must be configured. If the files are improperly configured, it will also lead to a series of unforeseen failures, which is not practical for beginners. Secondly, after windows is successfully loaded, the system startup time will be prolonged because the files of config.sys and autoexec.bat will be transferred to drive the optical drive every time the system is started. If the files of config.sys and autoexec.bat are blocked, sometimes the optical drive will not work normally under windows.

X. An illegal error occurred when installing windows to the system configuration.

　　This kind of fault is generally caused by the damage of the memory stick, which can be solved according to the method of memory maintenance. If it doesn’t work, the memory stick will have to be replaced.

XI. The system automatically restarts many times when windows is started.

　　This kind of fault is generally caused by the quality problem of memory chips or power supply. Of course, the system restart may also be caused by poor heat dissipation of CPU or other man-made faults, which can only be eliminated step by step by elimination method.

Twelve, memory maintenance method

　　After the above failures, if the memory is damaged or the chip quality is not good, if the conditions do not allow, you can use a soldering iron to remove each chip on one side of the memory to see if the problem can be solved. If not, you can replace the chip on the other side until it is successful (so the welder is afraid that the person who needs to repair the mobile phone can achieve it). Of course, it will get twice the result with half the effort if an oscilloscope is available. After this method is adopted, only half of the memory is available, for example, 64M and 32M are available. Therefore, there is no need to repair the small memory.
