I suspect a malware infection - I've seen this sort of issue show up at work.
The grub message is new to me - but the one's at work all involve the bootmanager is some way or another. Unfortunately our only solution at work is to either use System Restore (unsure of it's long-term effectiveness) or a wipe and reinstall.
There's nothing significant in the memory dump file that I could find.
Try posting over in the Security forums for help in determining if it's an infection: System Security - Windows 7 Forums
