From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I've recently got my PC up and running again but today it's rebooted randomly twice. What could this be a sign of? All advice is welcomed and appreciated. Thanks in advance.

How new are you to Linux?* /gen

Have you checked the output of, say, “journalctl -b -2”? This would give you a system log of messages that go back to two boot sessions ago and normally show you what happened just before that first shutdown.

This could be drivers, background processes, hardware, no way to know without starting by looking at logs. Hell, I’ve had a monitor crash out my system multiple times and I wouldn’t have ever guessed if I didn’t check my logs and dmesg output.

* to get a better sense of how to help you

First, sorry of the late response.

Second, running that command with the -r parameter it returns this:

FYI you can add -r to show the log in reverse order.
