Hello, 
  
During random times while playing AP, the game will suddenly crash with my monitor going into power saving mode and my pc freezing, which requires a hard restart. I have run the game in compatibility mode for xp sp 2, and xp sp3 and run it as an administrator. I have also updated my runtime libraties and graphics card drivers, but still no solution. my specs are as follows: 
  
Windows 7 Professional X64 
Intel Core 2 Quad CPU Q9300 @ 2.50Ghz 
4.00 Gigs of Ram 
NVidia GeForce 8800 GT Driver Version 8.17.11.9745 
Creative SB X-Fi 
  
Any Help is appreciated, Thanks.
