Safari in both MacOS 10.6.8 and Windows 7 will not open PowerPoint SlideShows but Firefox Will

Question

Having Created a PowerPoint Slide Show I find that it cannot be shown with Safari neither in Mac nor Windows 7.
The error message in Windows 7 is: "WebKitErrorDomain error 102"
The error message in Mac OS 10.6.8 is "Frame Load Interrupted."
The exact same Slide Show is easily shown with Firefox 28.0 in the Mac and Firefox 27.0.1 in Windows 7

To start with, my computer is the late 2008 model Imac, has 3g of memory …
I'm assuming you mean the Early 2008 iMac since there is no "late 2008" one. AFAIK, it came with 2 GB of RAM standard & the common BTO option would have been 4 GB, so can we assume that you have installed an aftermarket memory module to get to 3 GB?
I've already had it serviced, and was told that the issue was resolved, and was unrelated to hardware. Fifteen minutes after repair and setup, the exact same symptoms occur.
What repair and setup? Is this something you did after getting the iMac back from service? If so, what exactly did you do?
I had no initial problems with the install of either os (mac or windows), except to note that I couldn't install the apple software updates on the windows side.
Do you mean the Windows drivers or something else? Did you follow the Bootcamp install procedure exactly when reinstalling Windows or not?
I switched back over to mac to look for and install a video firmware download that I had located through these same forums.
What video firmware download do you mean? AKAIK, there are none for early 2008 iMacs.
No offense intended, but it is hard to understand exactly what you have done because while you mention much, you don't say a lot about the specifics for a lot of that. In general, it is best to concentrate on those things & keep the commentary to a minimum.
