DVD & CD Burner won't show up/function in Vista x64

[hemmy]

Vista x64 Ultimate no longer recognizes my DVD Burner or CD Burner.

Doesn't show up in My Computer, device manager, anywhere, and CDs do not auto play.

I dual boot XP & Vista and the drives work fine in XP, and work pre-windows boot.

They worked fine until a couple of days ago.

Anyone heard of a fix for this?

I rarely use Vista as opposed to XP but it does bother me.
