You don't have an integrated sound card if you have the stand alone Creative card you posted. You must install the Desktop System Software first with the chipset drivers and then install any missing drivers. Get the driver (and any other drivers) you need for your sound card at Dell Downloads. The F1 screen will list a problem with your boot process or bios that you should write down and post for more help.
