How to solve the abnormal memory? Counting several memory failures

Needless to say the status of memory, it plays a pivotal role in the computer, but although the memory is hardware, there will be faults, and the faults are quite a lot. Now this tutorial will be organized for you. There are six solutions to the frequent failures that everyone must look at.

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 improper settings, the system can only use 640KB of basic memory, the program is slightly The stool appears "Out of Memory" prompt, unable to manipulate. 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, too many applications reside in the memory, too many active windows open, and the application-related configuration files are unfair, which can cause the screen to appear. A lot of information about memory errors.

Workaround: This type of failure must be handled by clearing memory resident programs, reducing active windows, adjusting configuration files (INI), reinstalling systems 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 working 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 parameters related to memory. value.

Fault 6: The computer is upgraded for memory expansion, and a memory module that is incompatible with the motherboard is selected.

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.

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.
