Update: I bluescreened again yesterday with the same error (0x00000119, internal video scheduler error), and I'm beginning to think it may be a result of trying to game while GPU folding in 7. I'll be testing forthwith when I have time without folding running to see if it reproduces itself.

I'll start with the 181.71 for 7 KTNX!
In other words, it might not be the new drivers.
