Okay, so I was playing Civilization IV Warlords today and the sound cuts out, so I save and quite the game. After that I try opening it up again, and it skips the into videos, goes straight to the menu screen. I load up the saved game and when it's done loading the game locks up and a buzzing sound comes out of the speakers and I have to force quit to stop it. I try restarting my computer and I still get the lock up and buzzing when loading a saved game. This only started happening after the sound crashed the first time while I was playing.
