A. Some app starting up and running in the background occasionally? Are you using Vista? Could be the Indexing or Superfetch running while the game is active. In theory, these should not cause problems since they run as low priority tasks and should not affect other apps, but reality may be slightly different, as I've learned on Vista. If it's XP then I'd look more at other programs that are running in the system tray to see if they run randomly such as anti-virus software updating itself, or scanning files.
B. Heat? Are the CPU and GPU fans running smoothly? Are the CPU/GPU temps normal?
