I don't usually, but I had to this time. It still fukked up, but after a few reboots it worked again.Do you usually wipe the old drivers and do a clean install?
Back in the day, I had to do clean installs a lot, but it seems nvidia has gotten better about this in the past couple of generations. I've even had to use separate tools to completely uninstall everything associated with the nvidia driver. Luckily I didn't have to do that this time.
