Coke, when people take a normal HDD out of a machine and run it in another machine, it is very common to bsod on first boot but then on next boot, it works.
Going by that and how this may be similar - perhaps if you try to simply reboot after the 1st bsod - Windows might fix it automatically as in above scenario.
I dunno though because I don't play around with moving disks or To Go.
Other than that, the Office update likely will not cause bsods because they are not driver related at all. I suspect some other occurance going on with all of it.
