Extra White Space down Side of page - HELP!

[Strategic]

i have a standard A4 word doc with a page border - the border and information
within are fine however recently when i opn document there is an exra inch of
page on the right hand side its just white space. the border stays in and
doesnt move out, the white space just appears after about 5 seconds when you
open the document. it looks like i need to move all info and borders outwards
to make it even but everything wont go out the far and the rulers at the top
arent recognising the extra space either.

When printing the extra space remains.

i have looked at page broders, margins and setup and i cant see anything
wrong.

Please help rectify - i have tried everything i can think of.
