It is really easy as I said, only cost you some minutes watching carefully your system. If your system crashs, YOU have to find why. Not the community, not CD.

Install latest NVidia drivers, clean up your system, reboot.

Open Afterburner and watch carefully the clocks when the miner creates the tree. Sometimes (not everytime) the core spikes for a second above 2100-2200 MHz (depends on your card, 1070, 1080 or 1080 Ti). If your card & PSU cant handle such spikes, your miner or even your whole system will crash.

How to fix? Easy!

Clock your cards down to a point these spikes wont matter (usually a spike clock between 1950-2050). To make this easier, download the official CCminer and make your system 100% stable with -i 20. The CCminer will crash much faster with wrong clocks, so you can save time by testing things out. When done, switch back to CD and your system is 100% bulletproof stable.
