This article introduces the relevant knowledge of "what does the flashing red light of the computer host indicate". In the operation of the actual case, many people will encounter such a dilemma. Next, let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

The meaning of the computer host flashing red light: 1, the signal indicator light of the hard disk reading data; 2, the more frequent the signal indicator light flashes, the more frequently the hard disk reads data; 3, the host computer flashes red light crazily, generally due to the frequent exchange of data between cpu, memory and hard disk.

Operating environment of this article: Windows7 system, DELL G3 computer

What does it mean that the mainframe of the computer flashes red light?

1. The red light on the host computer is generally the signal indicator light for the hard disk to read the data.

2. The data read by the computer hard disk and the flashing of the indicator light are carried out at the same time. The more frequent the flash, the more frequently the hard disk reads the data.

3. The host computer flashes red light wildly, which is generally due to the frequent exchange of data between cpu, memory and hard disk. If the memory is too small or the ability of the cpu to process data is weak, or the amount of data to be read from the hard disk is large, it will cause the red light to flash wildly.

Extended data:

Red light flashing indicates that you are reading hard disk data, which is very normal during startup, and it will flash when running a certain program. If it is a large program such as a running game, it will flash or turn on directly. Do not worry, as long as there is no accidental power outage in the process of red light flashing, it will not cause any damage to the hard disk, which belongs to the normal scope of use.

The memory on the motherboard is often called a memory bar (long green bar), which is the part of the computer for data storage and exchange. Because when CPU works, it needs to exchange data with external memory (such as hard disk, floppy disk, optical disc), but the speed of external memory is much lower than that of CPU.

Therefore, we need a fast device to complete the temporary storage and exchange of data, which is the main role of memory. The most common color played by memory is to transfer data to the hard disk and CPU.
