IE8 32-bit crashes in Windows 7 64-bit on Dell Optiplex 760

We are having an issue with our computers we are using three Dell desktop models, we have Optiplex 755, 760 and 790. When we image these computers with Windows 7 64-bit, the 760 and 790 boxes are not able to use Internet Explorer 8 32-bit which is an issue because some of the websites we use for work are not available on 64-bit version of Internet Explorer. We have noticed that our error is coming up with DEP (data execution prevention) but our Optiplex 755 boxes work just fine with both versions of Internet Explorer 8.

I have tried starting Internet Explorer with no add-ons and that did nothing for me, i have reset all internet explorer options to default and still nothing. I have looked in to DEP in the BIOS and Windows itself and yet neither have helped. I'm not sure if maybe the DEP built into Internet Explorer 8 is my issue but I haven't been able to change it.
oh one question, are you using video card?? which?? may be issue with video card too
