New iMac setup assistant problems?

I have a brand new iMac literally fresh out of the box.

I am having major problems just getting through the initial setup assistant.

I didn't migrate anything this is just all from scratch.

The setup assistant is very very slow taking several minutes to recognize what I entered from the keyboard.

Screens were juxtaposed over each with the text overlapping. I can't see the question that it has the cursor in a blank field to answer to.

It gets hung in a loop asking for Cloud password info. It doesn't see what I typed in and just hangs.

A very frustrating initial experience with the new machine. Any advice is appreciated. Thanks.
