Many users do not use the POS cash register to perform routine maintenance on the product, resulting in various failures of the POS cash register in a short period of time, especially during the working hours. The appearance of the flower screen, which makes the cashier very helpless, today Xiaobian will introduce to you what fault factors will cause it to appear.
1. Long-term non-into-type machine cleaning leads to dust accumulation. Excessive dust in the machine can also cause crashes. 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 main frequency of the main board of the machine does not match the main frequency of the CPU. If the main frequency of the main board and the main frequency of the CPU do not match, the external frequency of the old main board is set too high, and the stability of the operation may not be guaranteed, resulting in frequent crashes.
3, the cash register software and POS cash register hardware are not compatible with 3D software and some special software, may not be able to start or even install on some microcomputers, which may have software and hardware compatibility issues.
4, POS cash register memory failure We all know that the shape of the POS cash register is very similar to our commonly used computer, especially the split cash register, the memory box is installed in the chassis, due to the installation is not careful, the memory is loose, virtual The quality of the solder or memory chip itself. 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 hard disk failure of the chassis is mainly caused by the 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 has overclocked overclocking during busy work, which increases the operating frequency of the CPU and may also 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. The hardware resource conflict of the POS cash register is caused by a conflict between the settings of the sound card or the display card, causing an abnormal error. 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.
