Sometimes the mouse will malfunction, the signal light will not be on, and sometimes the mouse will

Poor heat dissipation] The monitor, power supply and CPU generate a lot of heat during operation, so it is very important to maintain good ventilation, if the monitor overheats it will lead to color, image distortion and even shorten the life of the monitor. Working too long can also cause the power supply or monitor to dissipate heat poorly, causing the computer to crash. The heat dissipation of the CPU is an important problem related to the stability of the operation of the computer, and it is also the "hardest hit area" where the heat dissipation failure occurs.

Improper movement] In the process of computer movement, it is often loosened by a large vibration that the internal components of the machine will be loosened, resulting in poor contact and computer crash, so violent vibration should be avoided when moving the computer. 【Dust Killer】 Too much dust in the machine can also cause crashes. If the floppy drive head or optical drive laser head is contaminated with too much dust, it will lead to reading and writing errors, which will seriously cause the computer to crash.

Device mismatch] If the main frequency of the motherboard and the CPU clock do not match, the external frequency of the old motherboard is set too high when overclocking, which may not ensure the stability of the operation, resulting in frequent crashes. Resources.

Hello, I'm glad to reply to you, the display has no signal after the blue screen The keyboard and mouse light does not light up How to deal with it:1Loose operation memory or gold finger oxidation computer memory loose will cause the computer to fail to boot normally, this probability is relatively large, it is recommended to give priority.

Turn on the main computer, open the chassis side panel, unplug the memory module, and reinstall the memory slot. If not, it is recommended to replace the memory to a different memory slot and then try to start the test. If you have more than one memory friend, you may wish to insert one memory first, and the other memory is not inserted, try to start the test, if not, replace the other memory insertion, the memory is not inserted, and the test is alternate, and it is not ruled out that one memory is corrupted, or one of the memory is loose.

Second, the motherboard button battery discharge button battery discharge is very simple. There will be a coin cell battery on the motherboard. After loosening the tenon of the coin cell battery with a hand buckle or screwdriver, the coin cell CMOS battery on the motherboard will also automatically pop up, and then we can take it out directly by hand, leave the coin cell battery for ten seconds, and reinstall it in place, we are doing a boot test.

If the computer host turns on the monitor, there is no response, no signal, but the keyboard and mouse lights are on, we press the numlock button in the keypad area on the keyboard, press the lights out, and then press the lights on, indicating that the host has been operating normally, indicating that the monitor is connected to the host ** wire wrong, the specific solution is as follows. 3. The wrong connection between the monitor and the host is a problem that users often encounter. Generally speaking, these hosts are equipped with a discrete graphics card, and many users plug the ** cable of the monitor into the display interface on the motherboard.

This is an incorrect way to connect, causing the computer to not boot properly and the monitor to go black with no signal input. The integrated graphics card user must insert the motherboard display interface correctly, and the black screen of the monitor caused by loose cables or damaged cables cannot be ruled out. If not, it may also be that the graphics card is loose, or the gold finger of the graphics card is oxidized, take out the graphics card, wipe the gold finger with a rubber or dry paper towel, and then reinstall and test, it is not ruled out that the graphics card is damaged or the ** wire is damaged.

I hope it will be helpful to you, and you can always find the teacher if you have any other questions in the future. I wish you all the best in your life.

Hello dear, according to the situation you described, the wireless mouse fails and the cursor is not there and there is a green light on the mouse that keeps flashing? 1.The most common problem is that the interface between the mouse and the computer is not properly connected, which may be caused by poor contact or the driver is not installed properly.

Wired mouse to check the data cable interface or reinstall the driver. 2.The contact between the mouse and the mouse pad is too smooth, resulting in the mouse flashing frequency becoming faster, and you can choose to buy a real, *** mouse pad.

3.The frequency of the computer CPU will increase the number of mouse flashes, do not install too many floppy disks on the computer, do not run many programs at the same time, this will be the computer rotation speed will be slow, the mouse is stuck. 4.

The damage inside the mouse will also make the mouse flicker all the time, in this case, it is better to buy a new mouse to cure the symptoms. 5.It is also possible that the touchpad is damaged if the mouse keeps flashing, you can go to the buyer to ask or find a maintenance person to repair it, or reinstall the touchpad.

6.Whether it is a wireless mouse or a wired mouse, remember to charge or change the battery after a period of time.

The mouse light is on but it doesn't respond, and the possible reasons are as follows:

1. If your mouse is still lit, it means that there is no problem with your mouse itself, and there is no problem with your mouse interface.

2. At this time, you will search for various solutions on the Internet, and after reading it, you will be entangled, and you don't know which one should be, what I want to say is, based on the mouse This situation, you don't think about anything, turn off the computer first.

3. After shutting down, after 3 minutes, restart, in this process, you don't need to plug and unplug the mouse interface, after the computer is restarted, you will find that a problem is solved!

4. I think this situation is caused by the sudden crash of the mouse driver. Of course, if you try to restart and shut down and still can't solve the problem, you will have to use other methods, so read on.

5. Find Device Manager on your computer, first right-click on your computer and select Properties in the drop-down menu.

6. Go to Device Manager, find the mouse and other pointer devices and the Universal Serial Bus Controller, click the arrow next to it to see if there is a yellow exclamation mark, and update it if there is.

It is caused by the sudden crash of the mouse drive. Of course, when you try to restart and shut down the computer and still can't solve the problem, you have to use other methods, find the Device Manager on the computer, first right-click on the computer, and select Properties in the drop-down menu.

Go to Device Manager, find the mouse and other pointing devices and the Universal Serial Bus Controller, click the arrow next to it to see if there is a yellow exclamation mark, and update it if so.

Mouse considerations.

Inflexible movement means that when the mouse moves, the corresponding pointer on the screen does not follow the movement. In general, when you move the mouse in a large way, the cursor can move normally, but when you move the mouse in small steps, the cursor may not move.

The mouse works normally when it moves in large increments, but it does not work properly when it moves in small increments, indicating that the mouse is installed normally and the circuit is working normally, and the fault is that the rubber ball cannot effectively drive the grating disc to rotate. This is caused by the rubber balls, the left and right axles, the front and rear axles and the support wheels being too dirty, causing the rotation to be inflexible.

It may be a driver, reinstall it, if it doesn't work, it may be a problem with the mouse, the simple way is to find a friend to borrow a mouse and plug it into the computer, if it's okay, then there is a problem with your mouse.

It's exactly the same problem as yours, just update the driver.

Let's do something clean:

Enter safe mode, completely uninstall the mouse driver, then restart it, and install the driver again.

Here's why:

The host is too old, and there are many accessories that are badly worn out or even lose their functionality, the most likely being the CPU, graphics card.

Heat dissipation problems (very likely), due to the CPU or motherboard overheating, there is often a jam phenomenon, and then it crashes directly.

If you have a hard disk problem, you can consider that the hard disk interface is loose (very likely), it is recommended to unplug and reinsert it, or the power supply of the hard disk is insufficient (very unlikely).

The problem of CPU usage is too high, but also because the configuration of the computer is too old, resulting in the current configuration can not keep up with the program, and it is easy to crash when there are many programs running.

If the host memory is insufficient, it is recommended to add an extra memory module, memory is a major factor affecting the smooth operation of the machine, and insufficient memory is very likely to crash. It is recommended to buy a memory module, and it is best to add enough memory to 2G.

This has nothing to do with whether the light is on or not, if it fails, it is estimated that the frame is lost or there is a problem with the chip inside Return to the manufacturer for testing.
