Hey, I got a new GPU yesterday. It is a Gigabyte RTX 2070, and I upgraded from a 1060 6gb. CPU is Ryzen 7 1700x. I plugged it in and set it up for the first time about 26 hours ago now, and at random times the computer will just suddenly shut off. The screens go black and all the lights turn off immediately with nothing implying that it would happen. I don't know why this is happening or what to do to fix or alleviate the issue. It has happened 4 times now, twice right when I hit play on Minecraft, and twice mid-game on Rainbow 6 Siege. My assumption is it may be a temperature issue and it might be over heating, but when I paid attention to the temps both the GPU and CPU seemed to only hit around 60-65c. I haven't fiddled with overclocking or done anything besides installing the GPU. Any suggestions on what to try or how to find out the issue?
