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.

Mint, for me, was freezing up if something like Gimp was running in the background and it goes to sleep. Waking up, it appeared completely locked.

My system has 16 GB of memory, so I increased the swap from the default 2 GB page file to 16. It's been a few weeks, but I haven't seen a lockup.

My theory was that it was suffering trying to restore memory from hibernation. The only thing helping me was having a SSD, which would eventually catch up and bring me to a properly running state in a few minutes. If it was a spinning player it would never wake up.

Yes, you need enough swap to fit all your RAM's content to successfully hibernate/hybrid sleep. In the case of regular suspend to ram this shouldn't happen though

I have a feeling my swappiness setting was already aggressively paging, so I already had no space. I also turned my swappiness way down.
