Question GPU shuts down while gaming but GPU fans continue to spin at full speed

[FabioWest]

Hello, I am quite new to the PC-building world and may not be very familiar with the vocabulary! As the title says, my GPU randomly shuts down while gaming (specifically FPS games such as Apex Legends, MW: Warzone). Everything else seems to be working fine in my computer when I took look over. The water cooler and the LED fans are still working, and my CPU seems to be working as well. My GPU is the only component that seemed to be shut down and the LED was also turn off, but when I look at the fans, they are spinning a full speed. This usually happens after a few hours of gaming. Also when the GPU shuts off, my monitor also goes black and does not show a display but I still see it has power. I can hear the game and my teammates for a few more moments before it goes silent. The only "fix" is to restart the computer. My temps are usually GPU around 70C and CPU around 55-65C. Other games seem to be fine (such as League of Legends, Minecraft), so I suppose its the more intensive games that causes the shutdown? I run all my settings on low so I can get a high FPS rate instead of a high quality. I built this PC around July 2019, not even a year old and I have problems. Please help!

have you tried updating your BIOS? and all your latest GPU drivers from the support site first?

Hello and thank you for replying! So I don't know how to update my BIOS and if you could direct me to a tutorial or so that would be helpful. Also yes, all my NVIDIA drivers are all up to date.

Load Wattage: 422 W
Recommended UPS rating: 900 VA
Recommended PSU Wattage: 472 W

These are the results I got from that PSU calculator you provided me. I think my PSU is good enough because its a 750W. What are your thoughts?
