  1. hi, as i have upgraded the window 8.1 from window 7 everything is perfect in my system Dell optiplex GX620, but i can’t find the drivers for win 8.1 googled but couldn’t find audio/video drivers

    1. Use the drivers listed here, the Windows 7 82945 driver will work with Windows 8.1 and the audio driver should be inbuilt or can be obtained from the Microsoft update catalog.
