For the sound driver, check device manager to see if the device is installed. It might show under "Unknown devices" in device manager if the drivers arn't installed. Check under sound one too. If it has a yellow "!" - the drivers are probily missing and if it has a red "X" through it, then the card needs enabling. (Right click select enable). If this is all fine, go into control panel, and select sound options, and then there should be properties within there somewhere. Make sure your sound card is selected within there, there should be a drop down menu. If its not, sounds like the wrong drivers are installed. Lemme know what you find EDIT: With the driver back up, I would rather download the new ones when I have formated to Windows 7. Least you know you'll get the most up to date drivers.
