It's installing drivers after I uninstall old ones and reboot. I thought it was always a good idea to completely remove all gpu drivers before before manually installing new ones, which seems impossible if every time I uninstall old drivers and reboot, it auto updates them again and I can't stop it, and I'm pretty sure the last time it auto updated it wasn't the latest nvidia drivers.
Anyway, I just gave up and manually installed the latest nvidia drivers without getting rid of the old ones and it seems fine....so far.
