Here's a simple solution that worked for me:
Take off your CPU cover and spray every nook and cranny - particularly by fans, fan covers, and vents - with a can of DustBlaster, or other such product. Get rid of all that dust that accumulates over time in there. Put your cover back on and load up your game.
My AACW now completely loads before the intro song is even done playing. Turn resolution really flies by!
Try it; you'll like it!
