What is the reason why the blue light of the computer host keeps flashing and flashing

This means that your computer is working properly because you're plugged in. If the mouse does not respond, it may be a problem with the interface of the mouse, such as not being connected steadily, and there is a problem with the interface.

The indicator light of different computers is different, and if it is running normally, it is generally the indicator of hard disk reading and writing.

It may be that there is a bad contact inside the computer, and you can go to the after-sales service to repair it.

A computer can run without the mainframe. Know that if there is a problem with any of the hardware in the console, it will cause the computer to not function properly. So what's the matter with the computer host lights flashing all the time?

1. Generally, there are two indicators on the host, the power indicator will be on when the power is turned on, which means that the host is powered on and in use, and the indicator light of the hard disk will flash when the hard disk has read and write actions, indicating that the hard disk is working.

2. Whether it is a virus or a fragment reason, the hard disk read/write bridge is flashing fast, if there is a problem with the platter, or the power supply is insufficient, then the hard disk light flashing speed will be slow, and slowly turn on and off.

3. The indicator flashes very quickly, if a third-party defragging software is installed, it may be that the program is automatically executing scheduled tasks in the background, which can be ignored, if this does not happen, you need to manually defragment.

That's all there is to you about what happens when the computer lights keep flashing.

Take Dell achievement 5880 computer, win10 system as an example, the reasons why the red light of the computer host keeps flashing are as follows:

The red light on the main computer keeps flashing because the computer is performing data read, write and operation, and the computer may be overloaded. It should be noted that the red light will also flash all the time while playing the game.

The red light on the computer host is the working indicator of the hard disk, under normal circumstances, the red light keeps flashing means that the hard disk is working normally, and if it is not flashing, it means that the hard disk is busy, and if it does not flash, the hard disk is not working or the hard disk is broken.

If the red light of the computer host flashes relatively quickly, it is because the hard disk is reading and writing frequently, and the memory may be too small, in this case, you can increase the memory.

In addition, you can also turn off System Restore, although System Restore can save important files and settings on the computer well, but it increases the background read and write tasks of the hard disk, and turning off System Restore can improve the performance of the computer.

This answer applies to most models of computers under the Dell brand.

Hello dear, the blue indicator light of the computer host can not be turned on has been flashing analysis: the most common fault is poor memory contact, if the following operations are invalid, it is recommended to send it for repair. Processing:

Shut down (if short press the power switch is invalid, press and hold the switch until the power indicator goes out or directly unplug the power cord) Power off the case, replug the memory module, and wipe the gold finger with an eraser in one direction (the back of the thumb fingernail is also fine), if possible, it can also be installed in different memory slots, and then turn on after installation (before operation, you should also touch the wall with both hands to release your static electricity or wear anti-static gloves). If you don't know how to do it, it's simple: slap or kick the chassis once or twice (note the location:

The front of the shell on the left and right sides of the chassis without an interface in the back; Attention said: Don't push too hard, of course, don't * force). The above can be repeated, if it doesn't work, you need to replace the memory module.

If you have more than two memory modules, you need to test them one by one. Hope it helps.
