I'm using a desktop PC running Ubuntu 25, and I occasionally experience freezes that force me to perform a hard reboot. I'm looking for guidance on two things: first, how can I determine what's causing these freezes? Second, is there a keyboard shortcut in Linux, similar to the Ctrl-Alt-Delete function in Windows? Thanks for any help!

Honestly, you might want to switch from Ubuntu 25 to 24. Ubuntu odd-numbered versions are generally test builds, while even numbers are Long Term Support (LTS) versions. If you prioritize stability, sticking with the LTS version is usually a good idea!
First off, make sure you have a swap partition set up; it can help with system stability during heavy use. If you're not sure whether you have one, you can check by opening a terminal and running `swapon --show`. That'll give you the details you need!

Thanks! I'll check that out. What if I find that I don't have a swap partition?
