Game crashes whole PC

Recently i am encountering random crashes which not only freezes the game, but completely crashes the PC: screen freezes, not able to close the game, BSOD.
I am using an AMD card with the latest drivers.
Didn't have a any crash whole season, just started recently.
I see no event logs which could help me debug the problem.
Is there any game param which could tell me more? anybody experiencing the same?

check the windows log for what caused the BSOD

Nothing there, event viewer is useless, i meant that there was some game param which they introduced like in last league which produced more detailed game logs

happened to me twice yesterday, I have a 7700xt. played multiple league with the same setup never occured before, all parametres looking good, temp is more than ok, no big stress, nothing on event viewer. Everything freeze, then bsod, but I could still talk to my bro on discord. Had to hard reset.
