POS machine hardware memory failure quickly cleaned up

Memory is one of the most important accessories in a POS machine. Its role is unquestionable. What are the most common faults in memory?

Common fault one: no display at boot

This type of fault occurs in the memory module. Generally, the memory module is in poor contact with the motherboard memory slot. Just rub the rubber finger back and forth with the eraser to solve the problem (do not use alcohol or other cleaning), or the memory is damaged or Problems with the motherboard memory slot can also cause such failures.

The main unit speaker will beep for a long time (for Award Bios) due to no memory failure due to memory stick.

Common fault 2: Windows registry is often damaged for no reason, prompting users to recover

Such faults are generally caused by poor quality of the memory modules, and it is difficult to repair them, only one way to replace them.

Common fault three: Windows often automatically enters safe mode

Such faults are generally caused by incompatible motherboards or memory modules. Commonly used in high-frequency memory for some motherboards that do not support this frequency memory, you can try to reduce memory reading in CMOS settings. Speed ​​can see if the problem can be solved. If not, then only replace the memory module.

Common fault four: random crash

This type of fault is generally due to the use of several different chips of the memory chip, due to the difference in speed of each memory bar to cause a time difference, resulting in a crash, this can be resolved in the CMOS settings to reduce the memory speed, otherwise, only use the same type of memory . Another possibility is that the memory module is not compatible with the motherboard. Such a phenomenon is generally rare. In addition, there may be a bad connection between the memory module and the motherboard, causing the random failure of the POS machine.

Common fault five: the system resources are reduced after the memory is increased

This kind of phenomenon is generally caused by the incompatibility between the motherboard and the memory. It is common in high-frequency memory modules for some motherboards that do not support this frequency. When such a fault occurs, you can try to use it in COMS. Try to set the memory speed lower.

Common fault 6: Frequent memory shortage prompts when running certain software

This phenomenon is generally caused by insufficient space in the system disk. You can delete some useless files and leave some space. It is generally appropriate to keep around 300M.

Common fault seven: When booting from the hard disk to install Windows to detect disk space, the system prompts that the memory is insufficient.

This type of failure is generally caused by the user adding the emm386.exe file to the config.sys file. Just mask it to solve the problem.
