My mouse cursor has suddenly started to jump up & down.

What causes this and how do I correct it?

    It surely can't be an old rollerball model can it?

    Another probably unlikely one - if this is on a laptop and not a desktop is the trackpad turned off?

    It depends on your laptop. Usually it's a function key.

    Try moving your finger over the pad - if the mouse moves it's on. If it has just started playing up maybe you had it turned off but have inadvertently turned it back on.

    The laptop mouse works when I use my finger on it - it appears the problem is only with the plugged in mouse

    Turn the mouse upside down and look at the sensor (preferably with it disconnected from the computer, or the computer off*).

    Occasionally with optical mice you can get a hair or similar stuck on the underside of the mouse or trapped in such a way that it is protuding into the optical sensor area with the result the mouse will get confused because it's picking up the hair/dust moving as well as the surface the mouse is on.

    I've had it a couple of times in the last 15 years, usually gently blowing onto the sensor is enough to dislodge whatever it is.

    *This bit is to cover my backside if it turns out you get blinded laser/light source.

    Not if something is touching the trackpad while you use it, that is a major cause.

    I had problems with my wired mouse where the pages would scroll down further than my intention when using the wheel. So I opened it up, took it apart, reset everything and now it's fine.

    The usual issue with trackpads is that you can accidentally touch them when typing and that will obviously move the mouse. If it is on and always has been it's unlikely to be the problem but if you don't use the pad then turning it off is worthwhile imo. I always turn the things off and use a mouse as I can't get on with them and don't have the patience to learn.
