text: Normally Dells come with a recovery disc or install disks. It should have come with a CD that lets you install all the drivers back on.\n\nGo to control panel and then systems. Check your audio and internet settings and make sure they have been enabled.\n\nIf you cant find the sound driver, then go to http://www.soundcard-drivers.com and install it back on after finding out from the systems menu what sound card you have.
