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.

    There was also a period where my work computer didn’t have enough swap space.

    Since I am still quite new to Linux, is swap space referring to swap RAM?

      swap space is a dedicated place on your hard drive that the OS throws stuff to when there isn’t enough ram for everything. this is called swapping. since the hard drive is involved, swapping can slow things down a lot. if you get close to filling both ram and swap space, the machine starts shedding load by killing programs.
