Just lately I have been having a problem with Windows 7 not starting, about 40% of the time. I get the full Windows dialog boxes asking me whether I want windows to try to fix it etc and ultimately I always manage to start but it's a little worrying. Coincidentally my preferred voice model in Dragon NS 11 has become corrupted (Dragon is about the only reason I run Windows) though I don't know if there is a connection. Should do a reinstallation of Windows 7? Any help appreciated. Tom
