What s the deal with the mouse pointer moving on its own?

There are several scenarios that can cause this phenomenon.

1. The mouse is broken.

2. If it's a mechanical mouse, see if the ball is too dirty.

3. If the mouse recognition is not good, you can try to reinstall it.

4. There is a virus, it's time to check the virus.

5. If the mouse does not have a cover on other machines, it means that the system is broken, reinstall the system.

The above situation is relatively common.

It may be that the sensitivity of the mouse is too high, if you want to adjust it, click Start - Settings - Control Board - Mouse - Pointer Options - Select the pointer movement speed (depending on the situation, it is recommended to adjust it in the middle)!

I've also encountered this phenomenon, sweating ......At first I thought I was dazzled, my hand didn't touch the mouse, but it moved ...... on the desktopLater, I found out that it was because the mouse pad was too slippery, and then the mouse rope became entangled with the large number of computer wires under the desk, so that when I pulled the mouse farther, the rope would slowly drag the mouse back!

The mouse may not be placed on the mouse pad, or the mouse pad may be placed backwards, and there may be a problem with the photodiode inside!

The principle of an optical mouse is different from that of a scroll wheel mouse.

Inside the optical mouse there is a light-emitting diode, and the light emitted by this light-emitting diode illuminates the bottom surface of the photoelectric mouse (which is why the bottom of the mouse always glows). A portion of the light reflected back from the bottom surface of the photoelectric mouse is then transmitted through a set of optical lenses to an optical sensing device (micro-imager) for imaging. In this way, when the optical mouse moves, its movement trajectory is recorded as a set of coherent images taken at high speed.

Finally, a special image analysis chip (DSP, i.e., digital microprocessor) inside the photoelectric mouse is used to analyze and process a series of images acquired on the moving trajectory, and the movement direction and distance of the mouse are judged by analyzing the changes in the position of the feature points on these images, so as to complete the positioning of the cursor.

It should have nothing to do with roughness or not. The problem should be that you need a mouse pad with good light scattering.

Change the mouse pad, because the mouse is photoelectric and relies on light reflection, so most of it is caused by the unsmooth surface of the mouse pad! Most of the mouse pads on the market are not smooth on the surface, so it is recommended that you buy a better mouse pad, which will not exceed 10 yuan!

Have you run QQ pet sitter software? This software can cause this and there is no problem.

Hehe, I didn't use the mouse pad, I put it on the book, and it's the same, move slowly haha, what are you worried about, it's not good for the computer to become fully automatic!!

.A little vignette ha:

Once when we were in a programming class, it was clear that the output of ** was in Chinese, and the platform was running in English, which was also correct.

I asked the teacher to come and see it, and he looked at it, and then debugged it, and the result was a sentence, Well, the computer is intelligent. I'm ri

Maybe you have two mice installed, and the other mouse is shaking due to the friction of objects or something, hehe, I once had this problem, and I even went upstairs to hell.

It's a matter of mouse settings, you can go to the resource configuration and set it again!!

Normal phenomenon

It's not going very fast.

The problem with the mouse, after changing one, if it still doesn't work, it's a virus.

It is recommended to try a different mouse first, if it is still like this with a different mouse, it is your motherboard problem.

Recently, some netizens reported that her computer mouse pointer kept jumping, what is going on? Let me tell you the reason and solution for the mouse pointer to keep jumping, I hope it can help you!

Solution 1 for the mouse pointer to keep jumping:

1. Check whether the mouse pad where the mouse is placed is too smooth, you can change the mouse pad to try.

2. To see if there is a problem with the driver, you can uninstall the driver first, and then reinstall it.

3. If the interface of the mouse is broken, then the mouse can only be replaced.

4. Wipe the sensor of the mouse with a cotton cloth and clean up the debris of the sensor lamp, so that the sensor of the mouse is no longer affected by the debris.

5. Adjust the accuracy of the mouse.

It enables the mouse to adapt to the running needs of the computer.

Solution 2 for the mouse pointer to keep jumping:

1. Causes of mouse pointer jitter.

1. The adaptability of the old machine is poor

Old users still retain the original serial port mouse in the process of computer upgrade, and this kind of mouse can have a com interface in any class.

2. Radioactivity outside the computer.

Signal Disturbance:

Computer hardware works at a certain frequency, and if you notice a change in the frequency wave, it will cause the mouse pointer to shake.

3. Affected by stray light from the outside world

In order to pursue the beauty of the appearance, the mouse has good light transmittance, if there is a bad phenomenon of light shielding, if there is a strong light disturbance, it will affect the light signal transmission of the mouse, and the mouse will shake.

4. Poor mouse quality:

If the quality of the mouse is not good, the working frequency of the mouse is unstable due to the influence of indoor temperature, and the mouse will shake.

5. The core wire of the cable is broken

The four core wires at the mouse port are bent back and forth by the mouse, and after a long time, they will be broken, resulting in irregular mouse movement or even freeze motion.

6. Problems with mouse pads:

Whether the mouse pad is clean and rough.

Whether it is good or not, and whether the mouse pad is placed smoothly or not, will affect the mouse pointer.

Many users have encountered the situation of mouse pointer messing in the process of using the computer, and what is the reason for the mouse pointer messing around? And how to solve it?

1. The mouse pad is uneven. Lay out the mouse pad. When encountering the mouse movement, first check whether the mouse pad is flat. If it is not flattened, it will cause the mouse to move, clean the mouse pad.

2. Mouse into dust: clean up the gray layer in the mouse, the rolling beads of the mouse have gaps, easy to enter the ash layer, stuck rolling beads, it will cause the mouse to move, you can disassemble the mouse, clean up the ash layer.

3. Something is pressing down on the keyboard or something has fallen into the keys of the keyboard. Clean up the keyboard to ensure that the keyboard keys are used normally. If something presses against the laptop's touchpad or presses down the keys on the keyboard, or something gets stuck in the keys, it will cause the mouse to move.

4. There are Trojan horses or viruses. Solution: Use antivirus software to clean up Trojans and antiviruses, if there is a Trojan or virus in the computer, the mouse may move, you can use antivirus software to clean up Trojans and viruses.

5. Whether it is remotely controlled. Turn off remote control, sometimes you may choose to allow to be controlled when using remote to solve problems, but forget to end remote control, such as using remote control in QQ, so you can check whether there is a situation where remote is turned on when the mouse is moving.

6. The mouse driver conflicts with the system. Remove the tick from the quick mouse initialization. Sometimes there may be a conflict with the system, so select Control Panel, find the mouse, and uncheck it before the quick initialization.

The above is an introduction to the content of the mouse pointer always moving around on its own.

1. The pointer moves randomly caused by the mouse pointer stalling.

Workaround: Click the "Device Manager" button. Right-click the "My Computer" icon on the desktop, select the "Properties" command in the shortcut menu that pops up, pop up the "System Properties" dialog box, select the "Hardware" tab, and click the "Device Manager" button.

Double-click the mouse device. Open the Device Manager window, the Mouse and Other Pointer Devices option, and double-click on the PS 2 Compatible Mouse option.

Cancel the fast initialization. In the pop-up dialog box, select the "Advanced Settings Mess" tab, deselect the "Quick Initialization" checkbox, and click the "OK" button.

2. There are foreign objects or keyboard key conflicts on the trackpad.

Workaround: Check and clean the trackpad and try using it to see if the mouse is still moving. Check and clean the keyboard for damaged keys and abnormal presses. Try turning the trackpad on and off to rule out the impact of the trackpad.

3. The impact of related drives.

Solution: Open the security software or the program that comes with the detection driver to check whether the driver is running normally and whether it needs to be updated. You can also ask the corresponding after-sales engineer for help.

Click the "Device Manager" button. Right-click on the "My Computer" diagram on the desktop, select the "Properties" command in the pop-up shortcut menu, pop up the "System Properties" dialog box, select the "Hardware" tab, and click the "Set Sail Calling Manager" button.
