What troubleshooting steps did you take so far? I would try these:

• different OS, maybe a live usb running fedora or ubuntu if it is possible to emulate the workload where this appears
• bios reset to defaults, no OC not even XMP
• memtest, either the memtest86+ boot iso or the runtime memtester can detect obvious errors
• long smart self test on OS drive and an fsck or scrub based on FS

Also the logs show a very old nvidia gpu which is not supported by the new driver. I don't know if this can cause crashes, haven't used one in ages, maybe someone else has more insight.

I'm using suspend on my desktop running Manjaro KDE. To reduce power usage it goes to sleep after 15 minutes of inactivity and wakes up on mouse or keyboard input. Aside from some flaky kernel versions and after underclocking an unstable EXPO profile it's pretty stable, even games continue to run after wakeup.

That monitor will hold it back. 1080p wouldn't be bad if modern games run without TAA blur, but most games require it. Even a cheap 144hz IPS 1440p will give you a better experience.
