PC crashing (so far) only with Black Ops 3

So my friends and I decided to pick up BO3 on sale for some nostalgic zombies fun. However, anywhere between 30 minutes to a couple hours in, my PC randomly crashes. I never get a blue screen or anything, the only thing that happens is my monitors just go black and I'm unable to do anything until I hold the power button on my case to force shut down. I'm just completely at a loss on how to even diagnose this, let alone fix it. This is the only game that ever crashes on me. I can play other games for hours at a time with no issue, sometimes I even leave a game running overnight if I'm hosting a server or something.

It looked similar to when my graphics drivers were crashing playing Satisfactory, so my first thought was to try and update my drivers. However, they were up to date and even after using DDU and installing them all over again, I still got the same problem. I've even done a clean install of windows and wiped all my drives and still nothing. The last time it crashed, my friend suggested I press ctrl+shift+win+B and that just made a beep sound and nothing happened. Reinstalling the game didn't work either (as is probably obvious since I reinstalled windows). I have tried playing in windowed and full screen modes as I saw that suggestion a bit, but it still crashes.

I did buy my GPU used so I'm concerned that there may be a problem with it. It's really bizarre though that it seems to only be this one game. Does anyone have any ideas on how I can fix this, or how I can better isolate what the problem might even be?

My specs are:

* Asus X570-Plus motherboard * Ryzen 7 5800X3D * Asus OC Edition Geforce RTX 3070 8gb * Corsair Vengeance 32gb 3600mhz RAM * Corsair RM850 PSU * Samsung 990 Pro 1tb + 980 Pro 1tb + 1tb WD Blue 3.5" 7200 RPM
