Industrial panel computer motherboards have the largest number of failures
among all machine equipment components. A common problem is that the industrial
control integrated computer does not display this failure when it is turned on.
So what caused this? Industrial Android Tablet Factory to tell everyone.
Industrial Android Tablet PC
We can check the BIOS first. The BIOS of the industrial controller
motherboard stores key hardware configuration data information. At the same
time, the BIOS is also a more sensitive part of the motherboard and is very
vulnerable to damage. Once damaged, the system will not operate.
There are four main reasons for summarizing the situation where there is no
display when the machine is turned on:
1. This type of failure is generally caused by the destruction of the BIOS of
the industrial computer motherboard by the CIH virus. Naturally, the failure of
the motherboard itself is not cleared and the system cannot operate. Therefore,
we can tell whether the BIOS is destroyed by checking whether the hard disk data
is intact or not. If the hard disk data is intact, then there is no such
thing.
2. It is also possible that there is something wrong with the expansion slot
or expansion card of the motherboard, causing the motherboard to fail to
initialize with no display after plugging in an expansion card such as an
external sound card.
3. The CPU frequency set in the CMOS of the non-leakage-free motherboard is
not correct, which may also cause a non-display failure.
4. The motherboard cannot recognize the running memory, the running memory is
damaged, or the running memory is not paired, which will cause the failure of no
display when booting.
