Not sure if this is a dvd drive problem or a motherboard problem. I have a Liton ihas424-98 dvd drive I just purchased. I've installed it to my Biostar NF325-a7 board on one of the onboard SATA connectors. When I boot the PC, it freezes immediately after detecting the drive. When I use an external connector via USB, it detects the drive just fine and I'm able to use it, so I don't think the drive is bad. What do you guys think the problem might be? I've updated my bios on the board to the latest version on Biostar's website with no change.
