When this host issue occurs, the first thing we need to check is the BIOS. The BIOS of the motherboard stores important hardware data, and the BIOS is also a relatively fragile part of the motherboard, which is very vulnerable to damage, and once damaged, it will cause the system to fail to operate, and this kind of failure is generally caused by the motherboard BIOS being destroyed by the CIH virus (of course, it is not excluded that the motherboard itself fails to cause the system to fail). So we can tell if the BIOS is corrupted by detecting whether the hard disk data is intact or not, and if the hard disk data is intact.
In addition, there are the following three situations that will cause the device to be turned on without display:
1. Because there is a problem with the expansion slot or expansion card of the motherboard, the motherboard does not respond and does not display after inserting the expansion card such as a sound card.
2. The CPU frequency set in CMOS by the jumper-free motherboard is incorrect, which may also cause a no-display failure.
3. The motherboard cannot recognize the memory, the memory is damaged, or the memory does not match, which will also lead to the failure of no display at boot.

The difference between industrial computer hard disk - EVOC
1. Hard disk speed
The speed of the hard disk is one of the important parameters to identify the level of the hard disk, and it is one of the key factors of the internal transfer rate of the hard disk, which directly affects the speed of the hard disk to a large extent. The speed of the hard disk refers to the rotation speed of the motor shaft in the hard disk, which is the speed of the hard disk in 60 seconds.
