HI guys, my pc isnt reading dvds in my Blu Ray dvd Drive that is actually in my pc or in a USB one I have. Both are in perfect order and the blu ray is near enough brand new, in device manager its showing a yellow triangle with an exclamation mark. Any idea's how to fix this? I have tried everything, unplugging the drive in the computer and plugging it in again, going into the registry as for the USB one I have tried every USB port in my pc and still nothing. Daemon tools dosnt work either on my pc so it has to be something with the System? Thanks Jay.
