Nvidia site is better as they are the ones making the updates so your fine.
Just bouncing possible ideas to hopefully help you out:
Was the new GPU an upgrade? Did you have another GPU before getting the 970?
Anyone think he should try running off intergrated graphics to see if it still has a BSoD without GPU?
Is that the card you were using before then?
Before you switched the cards, did you uninstall any and all AMD drivers completely?
If not, that may be your issue.
