Hello, My son put in a new graphics card so that we could have two screen at the same time now I don't have any sound. This is the message I get when trying to play a CD: Windows Media Player cannot play the file because there is a problem with your sound device. There might not be a sound device installed on your computer, it might be in use by another program, or it might not be functioning properly.
He installed a msi n8400gs graphisc card. HELP! I need sound to do my job from home.
