Fwd: HTML message rejected: MCE Errors and Crash/Reboot on Fresh Fedora Linux 44

After booting Fedora 44 (7.1.3), the kernel will log MCE corrected
errors nearly constantly, then crash my computer.

Starting a new Fedora Linux install on my Vivobook Pro, moving from
Windows 11, results in several crashes/reboots, about 1-3 times per
day. Switching to acpi-cpufreq driver has reduced this, but still to
about once per day. This event is seemingly random and interrupts my
daily activities. Likely high severity due to the crashes, but
otherwise unsure.

The detailed description: After using my ASUS Vivobook Pro for about a
year, I switched from Windows 11 to Fedora Linux 44 7.1.3 a week ago.
I never had any problems on Windows 11. Since then, I have been
getting crashes after several hours of not restarting. Leaving the
computer on overnight will cause a crash 1-2 minutes after logging in.
I have gone through multiple steps to remove this problem with the
assistance of AI. I reinstalled a fresh Linux (the same latest version
as of writing this, 7.1.3), live booted from a USB, dual booted with
Windows, and used the latest vanilla version
(7.2.0-0.rc2.260711.dd3210c4.322.vanilla.fc44.x86_64) but they all
seem to have the same problem. I checked a stress test on Windows 11
and saw that there was no errors reported through WHEA-Logger, it
doesn't appear to be a thermal problem, my CPU temps were at about 85
C average and 92 C max after stress testing the CPU.

Steps to reproduce (Note: no errors are logged when the lid is closed):

Install Fedora Linux 44 (KDE Plasma)
Create a user / login
(optional): Install Steam (I did this in my first and second installs of Fedora)
Wait for about 5-10 minutes for MCE errors in journalctl
Wait for an indeterminate amount of time for the computer to restart,
this is always under 3 hours as long as the computer is turned on

Where I found the errors, these accumulate every 3-10 minutes:

Final Note:

I'm a new software engineer, I only have about a year of college
experience, I had Claude AI hold my hand through this whole process,
debugging for hours and checking system files and logs. I didn't know
what half of it meant but I had a rough idea. If you would like more
information, or even a better report, go to this GitHub repo that has
Claude's response under "Claude Report.md". Good luck and I hope you
have a good day!
