I'd check the mouse settings.
The easiest way is to click the Start button, in the search bar type "mouse" and then select "Mouse", after that go to "Pointer options" and slide the motion bar up to increase pointer speed if it isn't.
The mouse pad is a sensor pad that can be adjusted for speed and/or sensitivity.
