Issues with site layout on PC browsers

Greetings! I just found out from my client that the pc version of this site using the Chrome browser looks overly spaced out and even some of the photos aren’t covering the background and the positioning being off overall. I was totally unaware because on my mac chrome browser everything looks fine.

Is there a way to fix this?
