If the mouse is connected to the system unit via the PS / 2 connector (a round socket on the rear panel, next to which there is sometimes a mouse image), it cannot be connected and disconnected in a “hot” way, i.e. when the computer is on. A short circuit may occur to which the PS / 2 ports are very sensitive.
If you see that the cursor does not move and the system does not respond to mouse clicks, turn off the computer using the keyboard. To call the Start menu, press CtrlEsc or Win. Use the Down arrow and Enter keys to select the “Shut Down” command and confirm the shutdown request by pressing OK.
Disconnect the mouse wire from the port and carefully, trying not to bend the pins of the electrodes, reconnect. there may be a problem in the absence of contact. Turn on the computer. If the mouse works, then you did everything right.
USB ports are designed for hot plugging. However, if the mouse connected via USB does not work, still turn off the system unit before changing the connector. rebooting can help.
If the problem persists, check the mouse on another computer. If the cursor moves and the keys work, the port on your system unit may be malfunctioning or there are software problems.
To identify the source of trouble, alternately connect obviously good-functioning mice to the computer via PS / 2 and USB ports. Usually you do not need to install special drivers. standard Windows utilities are also suitable. If no device is working. most likely a software problem.
