You probably trying to squeeze so much out of it, try lower your setting a little.
i tryed already from 100% to 80%
i works a little bit longer but again blackscreen.. now i will try 20%... if again comes a blackscreen i will open my windows and drop this s... out
Not the 100% to 80% but from 2075 to 2050 etc.
You will getting more help at mining section and which mining program you use would also help.
