“the windows was slow starting on a fast machine”
This means any of the possible:
a) Using the Ted2Go IDE? (if is something related to the IDE)
b) Compiling speed of a demo? (it’s true that MINGW compilations are slow – however only for usage licence is a great choice)
c) Running speed of a demo? (if the demo runs slow – if it’s not 3D it might be something with event processing (eating CPU cycles) – or if it’s 3D it might be something with the GPU/Directx drivers.
How about CPU/RAM usage is it normal? It happened to me once to get a terrible trojan that would boost my CPU usage to maximum. 
Still trying to guess any possible solution.
