I can understand that sentiment given how frequently you have the issue occurring. For some unexplained reason I only had the issue again one more time after I posted the thread and haven't had it since. The only additional step I took to what I originally posted was I did a restore health even though sfc/scannow showed no errors. I have no clue why it stopped but wouldn't be surprised if it happened again. I did play BF Hardline for a good hour and expected it to happen again but it didn't.
Are you using DDU to uninstall drivers? If not I would at least give that a try. I have nothing against AMD and had 5870's in Crossfire in the past without issues, but are you able to "borrow" an AMD card from someone and fire it up with AMD's drivers to see for sure if the problem goes away?
I don't see the issue getting enough traction on the Nvidia forums for them to set it as a priority. Likely, as you mentioned, the best hope is the next Microsoft significant update, but seems from what you previously said, they haven't even identified the problem yet.
