Why does the mouse suddenly lose control

I've had more than one occasion with the problem of the mouse flying around automatically, and I'm sure other friends have also encountered it. Although this is a small problem, it may cause you a lot of trouble, and here I will solve this problem by combining theoretical and practical analysis.

First, let's talk about software glitches. When it comes to this, everyone immediately thinks that the system is infected with a virus, or that the mouse drive is in conflict with the operating system. But there is another reason, which may not have been encountered by everyone, that is, you have fallen for the Trojan horse, and the system is remotely controlled for others.

For this kind of problem, it is recommended to use a floppy disk to kill the virus under DOS first, if it doesn't work, then please reinstall the system. In addition, if your computer is constantly surfing the Internet, it is recommended to **the clean software to detect and kill Trojans.

The next thing we can talk about is the failure of the hardware. First of all, we should be familiar with the working principle of the mechanical mouse: by moving the mouse, the rubber ball is driven, and the rubber ball rolls and rubs the horizontal and vertical wheel rollers in the mouse to drive the grid wheel to rotate.

The rim of the grille wheel is grille-shaped. Immediately on both sides of the grille wheel grille, one side is an infrared light-emitting tube, and the other side is an infrared receiving assembly. The infrared receiving assembly is a three-terminal device, which comprises two infrared receiving tubes A and B.

There is a hold-down wheel in the opposite direction between the horizontal and vertical wheel angles, which keeps the ball pressed against the two wheel shafts no matter which direction it rolls.

Connect to the host computer via PS 2 port or serial port. The interface uses four wires, which are power, ground, clock, and data. When working normally, the movement of the mouse translates into the rotation of the horizontal and vertical grid wheels in different directions and speeds.

When the grid wheel rotates, the teeth of the grid wheel periodically block the infrared rays emitted by the infrared light-emitting tube to irradiate the A and B tubes in the receiving assembly, so that the output terminals of A and B output electrical pulses to the control chip in the mouse. Because the two tubes of A and B are arranged vertically in the infrared receiving assembly, the moving direction of the part of the grille teeth clamped in the middle of the infrared emission and reception is up and down, and the angle between the receiving tube of A and B and the infrared emitting tube is not zero, so the electrical pulse output by the A and B tubes has a phase difference. The control chip in the mouse determines the rotation direction of the horizontal or vertical grid wheel through the phase difference of this pulse, judges the rotation speed of the grid wheel through the frequency of this pulse, and continuously transmits the mouse movement information to the host through the data line, and the host makes the cursor on the screen move synchronously with the mouse through processing.

Suggestion: Reinstall the operating system first to troubleshoot system issues; Check the settings for CMOS power management; If the CPU fan does not have enough heat dissipation capacity and the CPU temperature is too high, the automatic protection function of the CPU and motherboard will automatically shut down without any reason. power failure; Or the power supply of the host is faulty, and the voltage fluctuates greatly, resulting in irregular automatic shutdown or restart.

Or the voltage of the external power supply is unstable, and the stabilized power supply can be added.

There must be something wrong with the mouse, your mouse is optoelectronics, and it's no problem to change it.

Motherboard problem Easy motherboard replacement Otherwise it will burn out the motherboard.

Summary. Dear, the mouse will move uncontrolled for the following reasons:

The first is a hardware problem, there may be a problem with your mouse, some components are damaged, it is recommended to replace a mouse to try. The second possibility is that there is a mouse setting option in the system where you can set the speed of the mouse and other options. You can see if the settings have been changed.

The third possibility is that there are more than two people controlling your computer at the same time, and see if someone has installed remote operation software on your computer.

Why does the mouse move around when it is not controlled.

Dear, the mouse will move if it is not controlled for the following reasons: the first is a hardware problem, there may be a problem with your mouse, some components are damaged, it is recommended to replace a mouse to try. The second possibility is that there is a mouse setting option in the system where you can set the speed of the mouse and other options.

You can see if the settings have been changed. The third possibility is that there are more than two people controlling your computer at the same time, and see if someone has installed remote operation software on your computer.

Hope it helps!

A mouse is a very common and commonly used computer input device that can locate the cursor on the current screen and manipulate the screen elements where the cursor passes through through the keys and scroll wheel devices.

The originator of the mouse appeared in 1968, the American scientist Douglas Engelbart made the first mouse in California, named because it resembles a mouse, the standard name of "mouse" should be "mouse", the use of the mouse is to make the operation of the computer more convenient, to replace the cumbersome instructions of the keyboard.

Rolling Ball Mouse: Rubber ball driven grating wheel with LED and phototransistor wafer pulse signal sensor.

Photoelectric mouse: Infrared scattering spot irradiation particles, light source pulse signal sensor with light-emitting semiconductor and photoelectric sensor.

If it's not a touchscreen computer, I don't know why.

It may be the reason why the DPI of the mouse does not match and the main control chip cannot keep up. The following operations can generally be solved.

1. If it is an XP system, go to the "Start" menu---Settings" -- click "Control Panel" -- find the "Mouse" and double-click to open the mouse properties ---Pointer Options" -- remove the "Improve pointer accuracy" tick option.

Second, if it is a win7 system, find the "Control Panel" in the "Start" menu--- find the "Mouse", double-click to open the mouse properties ---Pointer Options" -- remove the "Improve pointer accuracy" tick option. Then in "Control Panel" - Mouse Properties "--Hardware" --Properties "--Advanced Settings" --Remove the "Quick Initialization" checkmark option.

It is possible that it has been controlled by some mysterious force.
