Closing the laptop lid and opening it after 60 minutes causes a BSOD

I normally close my laptop with the applications running. After 30 minutes to 60 minutes when I flip open the laptop, I see Windows 7 presenting me a  logon screen and when I logon it says it was recovered from an unexpected shutdown.

The error message was as below:
