Welcome to the zoo.
hella lotta crashes on benchmark recently - not just you
those are prolly the only algos you'll need for now
if you bsoded you prolly need to reinstall drivers. use google for that? dun worry about more recent drivers than nicehash recommend - it's usually ok for basic stuff
possibly also v1.7.5.12 is less buggy
depends how technical you are, but you can get more by changing tack slightly.
read the last day or so here. a newb was set up directly mining nicehash
