I see you've uploaded a document to google drive. While we can see how the document looks on our systems, we can't see how it looks on yours, so the text overlap problem you're referring to may not be apparent to us. It would be helpful, therefore, if you could attach PDFs of the document produced by both your systems to a post here (PDFs preserve the page layout whereas documents don't). You do this via the paperclip symbol on the 'Go Advanced' tab at the bottom of this screen.

It would also be helpful if you could confirm whether both systems are using the same:
• Word version
• Operating system
• Printer and printer driver version.
That's because Word uses information from the active printers driver to finalise the document layout. That alone can cause documents to format differently on different PCs or even by just changing printers.
