Hi and Welcome!
any DVD writer with an interface that fits to your motherboard should do.
There must be something seriously wrong with Win7 if some standard hardware like optical drives does not work and special versions ("Win7 compatible") are needed.
My personal favourite would be a Optiarc AD7241S. Sata interface and Lightscribe (which I personally consider a gimmick of limited use) capable.
Check www.lightscribe.com if they have a Win7/64 compatible version of the LS system software.
P.S.: I moved the thread to a place where it fits better
