Question Laptop locks up while playing games, audio loops.

[Villius]

Hi,

so, I'll begin by saying I've been looking for a solution that'll work for me for the last 3 1/2h, its insanely frustrating when this happens. There's no specific timing, it happens completely at random, had it happen after 10 minutes, an hour, 4 hours even, i don't see a pattern. My PC doesn't make minidumps, if that's important, let me know and I'll turn it on and try get somethingeventviewer shows no abnormalities apart from Event 41 (Kernel Power Critical because of unusual shutdown) and Event 167 (Hypervisor did not enable mitigations for side channel vulnerabilities)

Specs:
Katana 15 B13VGK
i7-13640H
16GB RAM
RTX 4070 Mobile
Win11 24H2
1TB SSD (No HDD)

Games this has happened on:
Dead By Daylight
Deep Rock Galactic
Tom Clancy's Rainbow Six Siege

This has only happened in said games probably because I don't play much else.
The only game that so far hasn't caused this has been Don't Starve Together

What I've tried so far:
Updated all drivers, A-Z, every single one i have available.
Stress tested my CPU and GPU (via Intel XTU, Furmark)
Monitored CPU and GPU Temps, they've never gone over 75C when the pc froze. (via HWMonitor)
Stress tested my RAM for an hour straight, the result I ended up with - 0 errors. (43 Loops via memtest64)
"Undervolted" CPU by adjusting Loadlines by 20 (Started at 150, ended with 130 both AC and DC)

HUGE thank you in advance, if you need any other info, let me know

If the option for creating minidump files is disabled, enable it.

What BIOS version are you on for your MSI laptop? Did you use an app to update your drivers? If so, that might've been a likely gateway for the culprit.

Have you tried undervolting the discrete GPU as well?

You could also try and use DDU to remove all GPU drivers(intel, AMD and Nvidia) in Safe Mode, then manually install the latest GPU driver sourced from Nvidia's support site in an elevated command, i.e, Right click installer>Run as Administrator.

I haven't tried that yet, but i can right now.

Should i look up a tutorial for this? I'm not that great with all this stuff, incredibly scared to mess something up or brick the pc somehow.
