With the popularization of automation, the continuous development of industrial control skills and the use of industrial computer control programs are also increasing. Let's comment on the common engine failures and correction methods of industrial computers.
First, after opening the IPC, the motherboard self-test is successful, but the system cannot be started from the hard disk.
1. Press the "Del" button to enter the CMOS hard disk parameter setting and startup sequence.
2. After using the optical drive or floppy disk drive, check whether the hard disk of the industrial computer has a boot system, or whether the hard disk has been partitioned correctly and whether the boot partition has been activated.
3. Use FDISK/MBR commands.
Second, after the industrial computer is turned over, the memory self-test does not match the actual capacity.
1. Check whether the motherboard memory (motherboard integrated graphics card) is shared with the motherboard memory, so that part of the memory can be divided into dividend memory.
2. Check whether the memory is small particle memory (that is, the capacity of each chip in the memory is less than 16M, for example, 128M memory should have 8 chips), because some old chips do not support large particle memory, and only half of the memory is displayed after insertion.
3. Because the motherboard uses a relatively special CPU, it occupies part of the memory as the instruction decoder for CPU instruction set conversion, resulting in a mismatch in memory capacity.
Third, the industrial computer cannot completely enter the system after it is started, it will collapse or blue screen
1. Check whether there is any conflict between system resources.
2. Are there any errors in the BIOS settings?
3. Replace the memory module.
4. De novo partition, format and install the operating system hard disk of the industrial computer.
