I was leaning towards asking you to change your PC RAM as a test. I felt there
may have been a problem with AutoCAD large memory allocation and failed RAM.
The problem relates to windows trying to load a 32bit DLL into a 64bit memory space.
There is software code complier options which allow for different size memory space which
means re-compiling the entire AutoCAD software; obviously an option you don't have access too.
However,a quick search of the internet software code forums turn up the article below. Try this at your own risk.

We have seen some cases where, despite a certified Video card and driver being installed, there were stability issues when enabling hardware acceleration in AutoCAD 2012.
AutoCAD would then crash with a Heidi Error and/or an Unhandled Access Violation Reading 0x0048 Exception at e8f8e897h.
These issues could be resolved by reinstalling the required version of Direct X which can be downloaded from here:
