The mouse can be used for a while and cannot be used for a while.

There are many reasons for mouse failure, such as the mouse is really broken, the mouse contact is poor, or the driver conflicts, etc. These factors will cause the mouse to malfunction. If it is really a hardware failure, it will be a bit troublesome and you can only replace it with a new one. However, if it is a software failure, there are still ways to repair it.

1. Hardware failure (recommended learning: PHP video tutorial)

1. Is the USB interface failure.

We can find a good mouse and test whether there is a problem with the USB interface.

2. Whether the mouse is damaged.

Check whether the mouse optical engine is glowing. If the engine does not light up, you can plug the mouse into another computer to see if it can be recognized.

3. Is the mouse in poor contact?

Plug and unplug the mouse repeatedly to see if the computer can recognize it, or replace the USB interface.

Motherboard problems, too much computer dust can cause similar situations.

Main manifestations: Symptoms are not obvious or frequent when the phone is turned on, but problems will become obvious or frequent after half an hour of use. Solution: Find a professional to disassemble and clean the dust. Excessive dust can cause problems such as static electricity on the motherboard, overheating of the CPU, and overheating of the graphics card. These problems will directly affect the service life and operating speed of the computer.

Through the above test, it is found that it can be used on other computers but cannot be used on my own computer. It is very likely that the software is faulty.

2. Software failure

Whether the driver is abnormal.

We can open "My Computer→Right-click→Manage→Device Manager→Mouse and other pointing devices" and see if there is an exclamation mark in the subdirectory of "Mouse and other pointing devices". If there is an exclamation mark, It means there is a problem with the driver.

When the mouse is not recognized, we can also open the "Device Manager" by pressing the Win R key and entering devmgmt.msc.

If you find an exclamation mark, you can right-click on the directory → Uninstall the device, then unplug the mouse and plug it in again. The computer will recognize the mouse again and automatically install the corresponding driver.

This problem is caused by insufficient power supply of the USB port. It may be that too many peripherals connected to the USB port cause insufficient power supply. It is recommended to use a USB HUB with power supply.

It does not necessarily mean that the mouse is poisoned. It may also be caused by your memory being too small. This happens when the CPU reaches 100%. You can press the Cral Alt Delete key/Task Manager to view it. .

But if such a situation occurs suddenly, it is probably poisoned. Check the next anti-virus software
