Having run Vista 64 Ultimate for 4 months without a problem I recently restarted the machine after installing and running Diskeeper 2008. Upon restart I was, as usual, prompted to enter my password only to receive the following message:

The user profile service service failed the login. User profile cannot be loaded.

Disaster!

I restarted the system several times attempting to boot in any of the other ‘modes’ such as ‘safe mode’, to no avail. The system would seem to crash out whenever hitting the ‘crcdisk.sys’ file causing the system to subsequently restart and round the wheel spun.I would like to add that I have never had any problems relating to the startup of Windows Vista since my initial setup and having been a heavy windows user for 9 years, thought I had just about finally clocked how to avoid these kind of heart-sinking problems. No such luck. (more…)
