clean install set wheel settings that are recognised.mouse moves around screen but cannot click on anything

thats it. any input/help. cheers

..

I think he's saying he can't click buttons, using the mouse.

Very strange but I'd suggest going into a window (SHIFT+F4) and see if clicking works then.

If so then it should work if you try borderless window full screen mode (SHIFT+F11).

Please let us know if that fixes it and which version of Windows you are using.
