i have an Compaq Presario F700 with Windows Vista 32-bit. so two days ago, i was listening to music and my volume suddenly stopped working. i restarted the laptop and the volume button says No Audio Output Device Installed. my dad tried to restore the laptop to a point where it was fine before. that also didn't work. i then updated all of my drivers with Driver Genius Pro. I restarted it and the volume was working fine again. then the next day the volume doesn't work AGAIN.
any advice on what to do? thanks.
