Recently bought a advent laptop 7095 , untill 1 week ago everything was fine.Hadnt booted it for about 1 week an suddenly no sound...theres nothing showing in device man...but strangly theres no system beep when the bios loads pre windows..there are no options in the bios to turn on or off the onboard sound,unless there are hidden screens that need to be accessed to turn the onboard sound on...im pulling my hair out here...please help before it gets a wheely bin wrapped around it heh.
