When you turn on the computer to run the system and software, sometimes it is inexplicable. Why does it cause the operation of opening the system or software to fail? In fact, it is because of the memory of the computer. Here Xiaobian teaches you how to deal with memory problems. Fault 1: The memory module is in poor contact with the motherboard slot, and the memory controller is faulty. After the power is turned on, the screen displays “Error: UnabletoControlA20Line” error message and then crashes. Solution: Carefully check that the memory module is in good contact with the socket or replace the memory module. Fault 2: The self-test passed. Running the application in the DOS state conflicts with the memory address occupied, resulting in a memory allocation error, and a "MemoryA11ocationError" prompt appears on the screen. Solution: Because the memory management file such as Himem.sys or Emm386.exe is not used in the Confis.sys file to set Xms.ems memory or improperly set, the system can only use 640KB of basic memory, and the running program will appear "OutofMemory". Insufficient memory), unable to operate. 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 unreasonable, etc., which can cause many information about the memory error on the screen. . 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 the virus; CMOS parameters are modified by the virus, first discharge the CMOS short-circuit, restart the machine, carefully check the hardware parameters after entering the CMOS, and correctly set the parameter values of the memory. 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 motherboard's BiOS to see if it can solve the problem, if it still does not help, you have to replace the memory.
