Unable to install nvidia in Ubuntu22.04.3 with Intel 13th gen i9 and Nvidia RTX 4070

My laptop (Intel 13th i9core gen, nvidia rtx4070) system crashes after few minutes of use everytime. I’ve installed Ubuntu 22.04.3, tried with 6.5.5-1-liquorix-amd64 kernel without success. My system still crashes even without nvidia drivers active. Btw I managed to install Nvidia drivers + CUDA Toolkit but the sympthom remains.

When it breaks all applications close and can’t open anything, not even my terminal. I’m suspecting that ther is no support for my hardware yet as nothing seems to work. Any guidance I’ve been struggling with this for days.
