I have a gigabyte GA P35 DS3L motherboard Rev 1, when I connect a DVD to the sata ports or to the IDE ports the DVD fails to recognize or read about half of my game disks. For example Red Alert 3 and Oblivion. When I took the IDE DVD and connected to my sons old computer it correctly recognized the game disk so its not the DVD Players (I have tried 3 different brands) 2 sata and 1 IDE. I updated the Bios to the latest revision, played with my bios settings and nothing. Any sugesstions?
