It doesn't sound like you need drivers but more like you want the software that creative provides to use these drives.
I.e. for the cdrw, i'm sure that windows detected it but maybe you mean that you need a program that supports the drive to burn with. If this is the case try using something like nero

And if for the dvd drive a quick search led me to the fact that you have the dxr3 decoder board that you need drivers for. I remember when this card first came out so what you are looking for is the realmagic hollywood + drivers as mentioned here (
