When i tried to start up my computer a little bit ago, it shut off automatically. I turned it on again and it works fine now. I didnt get to check the screen though. It was off when i turned the computer on.
I also installed wubi/ubuntu on my computer? do these relate to each other?
I think you had an update that triggered an update ... or you have a scheduled shutdown that was waiting for the system to be running so that it would do it's thing. (not the most intelligent software piece.)
