Have you tried updating the drivers for the soundcard yet?
Also, you say this problem came about after "getting booted in a room". Would you care to elaborate on what that means? I'm assuming it means it got bumped or kicked intentionally or unintentionally, and if that's what you meant, you might want to crack it open and make sure the soundcard is properly seated. Just press down on it firmly, but not hard, and make sure it's all the way in the slot. If you have integrated audio, forget this.
