What should I do if there is an abnormality in the memory

            Method /Step
Fault 1: The memory module is in poor contact with the motherboard slot, and the memory controller is faulty: the screen displays “Error: Unable to ControlA20 Line” after turning on the power of the host.
Solution: Carefully check that the memory module is in good contact with the slot or replace the memory module.
Fault 2: Self-test passed. Running the application in DOS state conflicts with the memory address occupied, resulting in a memory allocation error. The screen displays a message "Memory A11ocationError".
Solution: Because the memory file of Himem.sys or Emm386.exe is not used in the Confis.sys file to set Xms.ems memory or set incorrectly, the system can only use 640KB of basic memory, and the running program will appear slightly larger. ;Out of Memory & rdquo; (insufficient memory) prompts, can not be manipulated. These phenomena are soft faults. After writing the system configuration file Config.sys, restart the system.
Fault 3: The application running in the Windows system illegally accesses the memory, there are too many applications in the memory, too many active windows open, and the application-related configuration files are unfair, which can cause a lot of memory on the screen. The error message.
Solution: This type of failure must be handled by clearing the memory resident program, reducing the active window, adjusting the configuration file (INI), reinstalling the system and applications.
Fault 4: When running the application software under DOS state (such as game software running under DOS) in Windows system, black screen, flower screen and crash phenomenon occur due to software allocation and memory conflict.
Solution: Exit the Windows system, enter the DOS state, and then run the application.
Fault 5: The program has a virus, the memory program resides in the memory, and the size of the memory value in the CMOS parameter is modified by the virus, which will cause the memory value to be inconsistent with the actual memory size of the memory module, and the memory works abnormally.
Solution: Use anti-virus software to eliminate viruses; CMOS parameters are modified by viruses, first discharge CMOS short-circuit, restart the machine, carefully check various hardware parameters after entering CMOS, and correctly set the parameter values ​​of the memory.
Fault 6: The computer upgrades for memory expansion and selects a memory module that is not compatible with the motherboard.
Solution: First upgrade the BIOS of the motherboard to see if it can solve the problem. If it still does not help, you have to replace the memory module.
Six common faults and solutions are listed. Everyone has no patience to look at it. If you encounter a memory-related failure in the future, you can solve it yourself. I hope it will help everyone.
