One thing that you didn't mention is how normal speed ever returns. It sounds like every other run slow with normal speed between. Since a Restart has no impact, it's safe to say that the problem is being recorded to disk. That leaves one of two possibilities: The data file(s) (including temporary files) was left in a state which is causing the problem or some config info for Windows is being altered and saved when you shut down. I'd be interested to know what happens if you just turn off the machine without shutting down - between files of course. It might give you a clue if it runs correctly afterward. ~ JD
