I just get my ADK computer in, and it seemed to be working ok, but when I began recording my projects, every time I save, Sonar stops responding and it kicks me out even when only running a few plugins and nothing else. I have literally only had the computer for like a week and it is pretty much the same as when I bought it, except I install Quantum Leap Symphonic and a few effects plugins. I'm running Sonar 8.5 producer 64 bit, PreSonus Firebox, Windows 7, 6 GB ram, and I have the OS on a separate hard drive than the audio files and projects. I've alreadly looked through the threads on optimizing Windows usage and most of it was already the way my computer was set up.
