I used to get the "nvlddmkm stopped responding and has successfully recovered" from overclocking.
Even though you may not be overclocking, try reducing the core clock 50MHz-100MHz and see if the error stops.
I'm not sure about Gigabyte's motherboards but, in the bios try setting the pcie x16 lane for your gpu to Gen 4.
