Hi.
I think you have a problem which even I, myself, ran into when I first got this Windows 8 PC back in June for my birthday.
Could you let me know what you were doing at the time when you got this error screen? Were you playing a game, watching something, or just even browsing the web?
The Auto-Update feature may have something to do with it (however it is extremely unlikely). I noticed a big bug in Windows 8 with the updating which created a loop of problems and the only way to ever see the desktop was to restore all your files and "reset" your PC from the advanced boot options. Microsoft need to get their exclusive Microsoft-branded hats, the soda's on the table and get to work!
