Hi Apathy,Mini D, Eagler.
Thanks for the info.
Yup I kept a log and with the help of the link posted by Eagler I found it.
I had enabled "Fast Shutdown" in the registry setting it back to the previous setting cured it and all is well with the world again.

Can't understand Why I missed it when I was working back through what I had done.
Didn't know about holding the power button for 4 secs, Nice one Mini D.
Thanks again all.
TTFN
