Hello, could you attach a DxDiag log file (windows search -> type "dxdiag" -> launch the app and click "save all information" -> upload the log file here (or right-click to "archive" it first into a zip file if the forum doesn't allow raw log uploads).
It's possible that you might have some sort of old input device driver installed that could be messing with mouse inputs.
