After replacing the last SATA DVD drive with another, I've concluded that the issue either lies with the motherboard or possibly Vista.

Out of the blue, for no reason, the drive just opens. This even happens while I'm listening to a music CD.

This was not an issue when I was using a PATA DVD drive on this board. Has anyone else seen this issue?

If not, anyone have a clue what could be causing this?

Thanks.
