Hi! I'm a newbie, & I have a problem I know you`ve heard before, my PC had been acting up recently (slow-ups, freezes, etc.) & I had experienced a virus situation (cleared up by AVG), so i've had a few problems, lol. One day though, when I turned my PC on, my desktop wouldn't appear, I went to safe mode, no desktop there either, so I rebooted to my PC start-up point & now I have no sound. I try to install a sound driver, Windows tells me it doesn't work on the system I have. My PC is a hp pavilion a317x.
