For the past few months, I've been experiencing random freezes while playing games. This frequency of these freezes depends on the game I'm playing. Some examples:
- REPO: freezes about 30 minutes in, sometimes longer, only seems to happen on later levels (=larger maps), but thats mostly speculation
- No Mans Sky: freezes about 30 minutes in
- Minecraft: Only 2 freezes in about 20h of gameplay
- Modulus Demo: Freezes anywhere between 2 minutes to 50+ minutes after starting the game
- Dyson Sphere Program: Freezes 10 to 30 minutes in
- Factorio: No freeze yet
- Silksong: No freeze yet
- The last of us 1 & 2: No freezes (but tlou 2 experienced unrelated issues later)
- Dispatch: No freezes
- Detroit Become Human: One singular freeze about 1h into the game, no freezes in my 3-4h after
- Stardew Valley: No freezes
- Beat Saber: No freezes
- Subnautica: No freezes

When one of these freezes happens, I usually hear a short buzz, afterwards audio is dead. My monitors remain frozen on the last frame, numlock/capslock stop working. SysRQ doesn't work, an active SSH connection to the PC becomes unresponsive and trying to reconnect it is not possible (host not found). The only thing I can do is hard reset the computer.
I have not been able to retrieve any logs about this crash anywhere. Journalctl stops before the time of the crash.

I have a dual boot system, with one ssd for arch and one ssd for windows. After moving REPO to the windows system and playing it there, I have not experienced any freezes in it. In general, I haven't had any issue like this when booted into windows for the whole time I've owned this PC.

Some more system info:
Hardware:
CPU: Intel Core i5-12600K
Motherboard: MSI B760 Gaming Plus WiFi (MS-7D98)
RAM: 16 GB DDR5-4800 (2×8 GB Kingston KF548C38-8, JEDEC, no XMP)
GPU: NVIDIA GeForce RTX 3060 LHR (ASUS)
Storage:
Crucial P310 2 TB NVMe (Linux)
Micron 2550 1 TB NVMe (Windows)
Monitors:
Acer KG272 S3 @ 1920×1080 180 Hz (DisplayPort)
ASUS VY279HGE @ 1920×1080 144 Hz (HDMI)

Software:
Arch Linux
KDE Plasma 6.6.5
Wayland
NVIDIA nvidia-open 610

Things I've tried, that didn't change anything:
- Use nvidia-580xx-dkms instead
- Use lts-kernel
- Use X11 session
- Disable iGPU
- SSH connection trying to capture logs
- Stress test GPU
- Monitor GPU, CPU, RAM usage while playing games (mangohud, nvidia-smi) (no obvious change before the freeze)
- Disabled PCIe ASPM
- Probably a few other things i forgot

I am pretty new to arch (only have been using it for a few months) and somewhat new to linux in general, so please excuse any wrong/missing terminology.
I've looked for similar issues on here, but everything I've found had differing issues or solutions that didn't work for me.
Testing this issue is pretty annoying because sometimes I just get a "lucky session" where no freeze happens over a longer period than usual, which means it's hard to determine whether or not a change has actually changed anything or not. Testing the frequency of crashes is basically impossible. I have found no way to reliably reproduce them within a reasonable time frame.
