Mouse Configuration Checks
When a mouse is not working in a Windows operating system, re-start the computer from safe mode (press F5 key when you see the starting windows message). This starts the operating system with the most basic mouse driver available. Incase, the mouse does not operate in safe mode too you must check the mouse hardware and the port to which the mouse is connected.
If the mouse works in safe mode, then the problem exists with the driver you are trying to use with it. There is a possibility that it might be corrupt or it might be having a conflict with some other driver. In order to check the driver, check the Device Manager. If Device Manager shows a conflict with the mouse, remove the driver and allow the system's Plug and play process to reinstall it.
