What do I do, when my PC freezes?

Windows has ctrl+alt+del, does Linux Mint has something comparable? The only thing I know about is REISUB, but that borked my PC, so I am hesitant to use that again.

Are there any remaining alternatives to waiting and/or using the power button?

Edit: Thank you all for your insights and possible fixes. Crashes usually happened when I was running (cpu/ram?) heavy workload. Increasing swap space was not even on my radar, so I did that now. :) Hopefully Mint will run more stable now.

    Could be a GPU driver bug. I get them occasionally with amdgpu. In this case only hard reset works (no it’s not a hardware problem, Windows never freezes like that).

    BTW you can get logs of the pervious boot using journalctl -b -1 command. Useful for debugging freezes like this.
