PowerPoint file crashes PowerPoint upon opening

I have a very perplexing situation on my hands.
I have 2 PowerPoint files that crash PowerPoint when attempting to open them. The problem is that this is only happening on some computers. All the machines I have attempted to open the files on are running Windows 7 and have Office 2010 installed. The computers also have Office 2010 SP1 install so I have ruled that out as an issue as well.
Any ideas?
