I don't know why you may be having these troubles. For the speed issue, I would check the Pachyderm properties to see that it is indeed set up use multithreading. If not, it would definitely take longer.
Regarding blue screens - The deepest my code goes is the .net framework, so the deep code that might cause blue screens is not mine.
This is the first time in a decade I have been told Pachyderm causes blue screens, so I'm inclined to think that it has something to do with your machine. The algorithms in Pachyderm will attempt to leverage your entire machine, excepting the graphics card, so it may just be falling on a problem with your hardware. I would do what the blue screen says and check for a bios update. If that doesn't work, try contacting the manufacturer.
