Some of these problems seem to be basic mining configuration problems which google will quickly solve for any new miners that are lost.

...my problem right now is 1 of my trusty 750ti's died right as the hashrate skyrocketed, so now I'm sadly down to only 5 cards.  If only I had not sold off my other 14 cards back in 2015 when it seemed coins were dying everywhere   (lost 1 gpu in 3.5yrs, so not bad overall.)
