Question : Problem: Scrolling display is rolling in waves, nothing I can find fixes it

I don't know if this is hardware, such as settings on my monitor, or software, such as mouse - I have tried adjusting every possible thing and can't get my display to behave the way it used to, a few weeks ago...and I don't remember anything about when it started happening or why...

When I use the mouse wheel, it rolls in large blobby waves, and when I use the scroll bar, the same - if I click the mouse on the scroll bar, the page will take off rolling up or down, sometimes way past the line or point I wanted to stop, so it is imprecise and it is literally making me ill, like dizzy, to sit here and try to see. On Outlook, if I delete an email, there is a big wave.

In other words, the screen goes jump-jump-jump-jump....which is annoying!

I have adjusted the monitor, whatever I could find in display properties, changed the mouse, reinstalled mouse software - it seems hopeless.
what can I do to fix this?

Thanks very much for any help.

And please DON'T swap them around with the power on.
Turn off the computer AND unplug the monitor's AC cord before switching its video plug to a different jack.
