I installed the latest nVidia drivers about 4 hours ago, crashed my computer and required a complete OS reinstall. Thinking I may have done something wrong or perhaps it was just a fluke I reinstalled the latest drivers, same thing. Four hours later I'm here to warm people.
IDK why, how or whatever but, the latest drivers killed my system, twice. Install at your own risk. Hopefuly it's isolated to just my system but, I highly doubt it.
Good luck
UPDATE: apparently it's not isolated to my system:

UPDATE II: nVidia forums is overloaded with people having the same issue, apparently it affects multi monitor setups, so if you have VR you'll get hit, most likely. nVidia is slipping of late and this particular "slip" can brick your card, your system or at the very least take hours to fix. What a mess.
