Apex legends crash - HARD REBOOT REQUIRED

GAME CRASH

I play for 15-2 hours.. no crash. Seemingly randomly I crash with no error and my pc goes into “broke mode” where my disk runs at 1kb/sec and my cpu quickly goes vegatative (basically) and I cant open my game because its still acting like the game is open. I also get somewhat choppy audio, have gotten 0x00000 at 0x0000 error but soon realized I needed to fit new ram in, fixed it. The crashing is still happening and I have to hold the power button to even restart it so that I can play for another 15-2 hours
