You're welcome.

As you can see by my specs, I think 7 is worlds better anyway for all sorts of reasons. Stability-wise, both operating systems are similar and well, though.

There might just be something inherent to your system, such as firmware needed for the drive or motherboard (or that tap driver works well under 7 but not 8), but I say if you're happy with 7 then more power to ya. Enjoy.
