I have a Sony Vaio VGN-FW139E laptop using Windows 7 Ultimate 32-bit. About a year(?) ago my cd/dvd rom stopped working properly. It only detects cds that i put in. I can't watch any movie or run a program that's on a dvd. Just doesn't detect it. I tried talking to the Sony Tech support, BUT they don't offer support since i upgraded to windows 7. So, i tried to uninstall-reinstall the driver, but still did not work. Anyone have a solution for this? My CD/DVD-Rom driver is an Optiarc DVD RW AD-7560A USB Device. So, please someone help.
