I did render on GIGABYTE GeForce GTX 1070 G1 Gaming and Core i5 2500. However never used this slow CPU for rendering, only GPU and had never crash.

Good, thank you for assistance. This is great tool in Blender.
No it is in menu: "Mesh -> Vertices -> Connect Vertices", this cut mesh like a knife.
Problem is that this bug is random but very often. In 2.78 RC1 and RC2 when the bug is activated I'm not able to connect the two selected vertices (with edge between vertices). When I open the file in 2.77 it is OK.
