The reason why the x86 sbc cannot be displayed when it starts up | GREATZC

 

The x86 sbc is a motherboard used for industrial production computer technology in industrial production sites. According to needs, it can be integrated into a wide temperature environment, can be integrated into a harsh environment, and can work under long-term load for a long time. It is precisely because of the stricter application regulations in the office environment that the x86 sbc is also one of the most faulty components of all industrial computer components. So, what is the reason why the x86 sbc cannot be displayed when it is started?

In the case of normal startup of the industrial computer without common faults, first check the BIOS settings of the industrial computer. The BIOS of the x86 sbc stores key hardware configuration data information, and the BIOS is also a sensitive component of the x86 sbc. It is easily damaged and, once damaged, may render it inoperable. This kind of failure is generally caused by the damage of the motherboard BIOS by the CIH virus. Therefore, we can check whether the data on the hard disk is intact to determine whether the BIOS is damaged.

In addition, there are three conditions that are not easily displayed when the machine is started.

1. The expansion slot or expansion card of the x86 sbc is not very good, so after inserting an expansion card such as an external sound card, the initialization of the motherboard fails and there is no display.

2. The CPU frequency set in the CMOS of the non-jumper motherboard is incorrect, which will cause the display to fail.

3. The motherboard cannot identify the running memory of the industrial computer, and the running memory is damaged or the running memory is not paired, which will also cause common failures such as no display at startup.
