Mice, like any other device, tend to break. However, malfunctions in the operation of devices do not always mean that they need to be replaced. Also, sometimes the system settings are changed by certain programs, sometimes the wrong mouse connection or damage to the driver files by viruses is to blame. In general, the reasons can be very different.
If suddenly your mouse starts moving slower than usual, it is quite possible that this is not due to a malfunction of the device; most likely, the pointer speed has been changed. Open the "Control Panel" and go to the mouse settings menu. On the Pointer Settings tab, set a speed that suits you, save your changes. If the pointer does not respond intermittently or continuously to mouse manipulation, check that the device is properly connected to your computer. If the mouse is connected to the PS / 2 port, turn off the computer, remove the plug from the connector on the motherboard and connect it to the similar port next to it. Turn on your PC, check if there will be any problems with the device in the future. Also, the mouse freezing can be caused by corrupted system files by viruses, so if you have a USB mouse, please reinstall the corresponding system driver. To do this, open the "Control Panel" and through the "Add or Remove Programs" menu, uninstall the USB driver. Find the USB 2.0 driver on the disc that contains the software for the mouse, keyboard, or other device that you connect through this interface. You can also download it online. Install it on your computer, after rebooting the system, check the operation of the mouse. If you have a wireless mouse, dead batteries may be the cause. Check their charge level. Also make sure that the signal is not obstructed by mobile devices in the vicinity of the adapter connected to the computer. Also, in the case of simultaneous use of a USB modem on your computer, the pointer movement may be delayed. To avoid this, use device connection ports that are remote from each other.
