This sounds EXACTLY like what is happening to me, but its super inconsistent.
Ryzen 9 5900x, and a 3090. I was on like 530 for nvidia drivers too, so I guess Ill try that despite it not seeming to help. I thought it was my CPU undervolt at first, because its per core and needs to be tuned over time, though I hadnt had a crash in like a month, (raising the voltage slightly after). I completely turned off my per core undervolt, and it seemed to go away...
I THOUGHT until I played tonight and crashed 3 times in a row instantly, full pc crash to reboot. one black screen (of which I had 2 before in like my first games playing). And then two half second flashes of BSOD which instantly failed (error code 41 kernel power) just before a "Dump file creation failed due to error during dump creation." error. I really cant see it being hardware purely, the CPU is basically brand new due to RMA, and has been fine. I dont crash in other games hardly at all.
I crashed trying to melee twice, and the third time, the game lagged to a standstill and quickly blackscreened. Its super weird that I literally played for 15 something hours without a SINGLE crash after turning off my undervolt, only for it to start doing the exact same thing, with LITERALLY NOTHING CHANGING.
