Thanks VoG™, Recovery is not a problem, Ive done that three times. What I really need to know is what is making it crash, and how to avoid it. When it reboots The "Egg timer" is blue as it should be and when it's loading it says SP2. So I am certain it's loaded. There is no problem or warning when actually loading SP2 from the disc, it goes through inspecting files, configuring etc as though there is no problem. Then when it gets to desktop, Crash.
