  1. What is the make/model of your power supply?

    What are your CPU and GPU operating temperatures at idle and under load?

    So the power supply is the RM850 Corsair , while the GPU temperatures goes around 65°and the CPU temperature is around 40° per core

    Are those temps while doing little/nothing or when under load (like when gaming)?

  5. Temps are ok. Assuming the PSU is working properly, it should be okay as well.

    Are you overclocking anything (CPU, GPU, memory)?

    Also, have you tested your memory (with a tool like memtest)?

    Video and motherboard chipset drivers and Windows updated?

  11. Go here and get the Valley Benchmark app. Install and attempt to run the benchmarks. Keep an eye on the temps to see how hot your GPU gets.

    This sounds like a heat and/or power issue. Could also be a flaky GPU (removing and using integrated video would help isolate).
