The mouse cursor can disappear either due to errors in the computer software or if the device itself breaks down. It is best to have an optional pointing device with you to determine the exact cause of the problem.
First, check the wires connecting the mouse to the computer and make sure the ports on the computer are in proper condition. Turn the mouse over and check if there are any foreign objects in the optical connector. Clean the mouse, if necessary, and test its operation. Also, if you have a wireless mouse model, the malfunction may be caused by discharged batteries or a weak signal from the devices, in this case, connect the mouse through a port that is at a minimum distance from it. Also, the problem of wireless pointing devices is their simultaneous use with USB modems. The signal from one device can interfere with the smooth operation of another, most often the mouse cursor either disappears for a short time, or simply freezes and does not respond to mouse manipulations. In this case, it is best to connect devices through ports on different sides of the computer, also do not hold the mobile phone close to the mouse adapter. If you have a laptop, check if the cursor disappears if you use this device as the main one. To do this, assign it the priority for use in the control panel and disconnect the mouse. If the problem still persists, then it's the software. In this case, perform a full virus scan of the computer and reinstall the motherboard software. Also reinstall the USB 2.0 driver. If you have a stationary computer, check if the device is connected correctly, try changing its connection ports and reboot the system. If possible, connect another device connected in the same way to the computer mouse connection port. If it also malfunctions, the problem is most likely related to the USB or PS / 2 interface, depending on the type of mouse. In this case, reinstall the motherboard driver.
