I too have had a big problem with DROPOUTS as long as I can remember. Dividing my C: drive into 2 drives helped me. I now have a partition of my C: drive (known as J:) for all of my project files. It worked great at first, until I started to record audio tracks...then I needed to reset my audio to the "default" settings and change the audio driver to "ASIO". No problems now.
Thanks for your suggestions.
