Summary of flower screen failure factors during POS cash register operation

1, long-term non-into-type machine cleaning leads to dust accumulation
Excessive dust inside the machine can also cause a crash. If the floppy drive head or the optical drive laser head is contaminated with too much dust, it will cause reading and writing errors, which will cause the computer to crash.
2, the machine motherboard frequency and CPU frequency do not match
If the main frequency of the motherboard and the CPU frequency do not match, the old motherboard will set the FSB too high when overclocking, and may not guarantee the stability of the operation, resulting in frequent crashes.
3. The cash register software is not compatible with the POS cash register hardware.
Three-dimensional software and some special software may not be able to start or even install properly on some microcomputers, and there may be problems in software and hardware compatibility.
4, POS cash register memory module failure
We all know that the shape of the POS cash register is very similar to that of the computer we usually use, especially the split cash register. The memory box is installed in the chassis. The memory is loose, the solder is soldered or the quality of the memory chip itself is caused by the inadvertent installation. The memory module contact fault should be eliminated according to the specific situation. If there is a problem with the quality of the memory module, the memory needs to be replaced to solve the problem.
5, the chassis hard drive failure
Mainly due to aging of the hard disk or bad sectors and bad sectors due to improper use. This makes it easy for the machine to crash when it is running. Special tool software can be used for troubleshooting. If the damage is serious, only the hard disk can be replaced. In addition, for motherboards that do not support UDMA 66/100, you should pay attention to the setting of the hard disk operation mode in CMOS.
6. The CPU of the POS cash register appears overclocked during busy work.
Overclocking increases the operating frequency of the CPU and, at the same time, can make its performance unstable. The reason is that the speed at which the CPU accesses data in memory is faster than the speed at which data is exchanged between the memory and the hard disk. Overclocking makes this contradiction more prominent and exacerbates the situation where the required data cannot be found in the memory or virtual memory. This will cause an "abnormal error". The solution is of course simpler, that is, let the CPU return to the normal frequency.
7. Hardware resource conflicts of POS cash registers
The error is caused by a conflict between the settings of the sound card or the display card. In addition, if the interrupt, DMA or port of other devices conflicts, it may cause a few drivers to generate an exception, which may cause a crash. The solution is to start in "safe mode" and make appropriate adjustments in "Control Panel" → "System" → "Device Management". For situations where an exception error is generated in the driver, the registry can be modified. Select "Run", type "REGEDIT", enter the registry editor, use the "Find" function under the menu, find and delete all the "primary keys" and "key values" associated with the driver prefix string, and restart.
