click here if you key in the ident key to the bottom left you should be able to get all the drivers, alternatively click here .Regarding playing MP3s your present media player should be able to do it but Media Player 10 is available for free download from Microsoft and I think its quite good, you don't have to delete the old one it just installs over the top. If the sound driver is not installed then regardless of what player you use you will get no sound. You need the sound drivers. As far as I know Media player does not play DVDs as standard and you need a codec as well. I'm not sure about this as I like PowerDVD and use that.
