Sometimes my entire screen will turn green requiring a reboot. This has happened while gaming but also while watching videos in browser. I'm trying out undervolting/underclocking using LACTL. Have you experienced this? What was the cause and how did you fix it?

Please excuse me dropping off the face of the Earth for a few days. Power supply is Corsair 750 W. Linux 6.14.6-109.bazzite.fc42.x86_64 AMD Ryzen 7 9700X (16) @ 5.58 GHz

That PSU sounds good enough to me.

Could be worth a motherboard firmware update?
and i would double check all the power cables.

It looks ike mangohud is an application to monitor stuff. I've never used it but you could give that a go - see if you're ever getting close to the 750W.

Thank you for your reply! I'll check it out. I need to try remounting and double checking cables still, I've just been putting it on the back burner. Oddly enough I experience this problem much less often when using Gnome rather than KDE.

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.
