I ran chkdsk /r, it took ages and so I left it overnight and by the morning it had shut down, when I restarted it, it ran chkdsk again. I let this complete (it took around 14 hours) looking at winlogon, the first time it appears to have crashed:-
The shell stopped unexpectedly and Explorer.exe was restarted.
