My Game Crashes Every Few Minutes

I appreciate the help you have provided, however I have had no success and my game still closes.  It will load, I get the resume game screen, sometimes into the lot, but then it crashes.

I could never get the DDU thing to work, sorry, I got tired of trying.  I am about to give up on this game.  It just won't run on this high end PC I bought just for this game.  I have gone as far as to restore the PC from the original settings, since it worked when I first got it, but now it doesn't work at all, the game just closes back to the desktop.  Here's my latest dxdiag, but I assume it will be the same thing.
