Dvd disk drive won't run DVD's. Makes alot of clicking, spinning noises but wont read disks. Went to HKEY areas and changed some things recom by other forums. Didn't work. Told needed firmware upgrade. Unable to find firmware for Optiarc DVD RW AD-7530A ATA Device because as near as I can find it's an OEM Device. Went back to Gateway(Notebook Manufacturer) and they don't have. Any suggestions? Ifu can't fix, I guess u install a new DVD Device or a new Notebook. Was also told by Gateway I needed a Codec upgrade.
