David has high end 17" Windows 7 laptop, but he's having issues with his optical drive after being reinstalled. Leo says there's a bunch of things it could be, like a damaged player or a broken cable. Since it happened after a reinstall, it may have missed the DVD player driver. David should check his device manager to see if Windows sees it. If it's not in there, then he'll need to install the drivers in order to use that player.
