I recently started playing FFXIV, since then I started noticing frequent shutdown.

But it's not a complete shutdown, the image of my 2 monitors goes out along with the mouse and keyboard leds, and at the same time I hear a very loud fan sound coming from the video card. By holding the power button and forcing a complete shutdown, I am able to restart the computer normally.

Shutdowns only occur while playing FFXIV. I've tested it on Red Dead Redemption 2 with the graphics settings at maximum and nothing happened.

Today, August 27th, until 2pm it has already happened twice. Both times under the same circumstances: I had the game in the background, and when I returned to the game window, the computer shutdown.

At first I thought the problem could be power supply as my power supply was only 550w for an RTX 2060 Super, so I bought a new 750w EVGA and the problem still remains. I've already performed temperature tests and they don't show any worrisome variation.

My setup:
Motherboard: MSI A320M Gaming Pro
CPU: Ryzen 7 1700
Graphic Card: RTX 2060 Super
Power Supply: EVGA 750w
Bios Version: 7A39v1I
