My dvd rw drive isnt working properly

[nero]

Since i made my windows 7 Ultimate from 32-bit to 64-bit my dvd rw wont respond.

When i place a dvd inside first it wont respond,then when i want to extract files to my desktop it goes very slow,about 2 MB

Nero did you check compatability before moving up to 64 bit?
