|Well, you Google for your computer make then search for drivers against its model number. You then download them and install them. Let us know the make and model number and we should be able to start the ball rolling.|
What strikes me as a bit odd though is you appear to be implying that there is sound on some of your games. It's unusual for sound to be so picky so I wonder if there are any settings that need tweaking in those particular games that are giving trouble. Did this happen immediately after the upgrade to 8? RAM and Graphics Card shouldn't have made any difference.
Always pop back and let us know the outcome - thanks
