Just choose a folder, doesn't really matter for now. We just want to get your card mining.
I remember me having that same BSOD atimkdag.
But that wasn't while starting up sgminer or so. I got it at random.
I believe i had to remove all the drivers, reinstall them all before installing any remote administrative software. Like Teamviewer or vnc.
Because my issue was i first installed vnc and tv and than i installed the drivers. That constantly gave me issues.
Install Afterburner as well if you haven't already..
