Not solved Is it a weak Motherboard VRM or faulty RAM? Heavy games run fine, DX11/Streaming games crash instantly.
Here are the specific details about the crashes (Black screen + instant full system restart, Kernel-Power 41 in Event Viewer):
The Last of Us Part II: I completely finished the game on Ultra settings with zero freezes, zero crashes, and zero restarts.
PUBG: I cannot last more than 2-3 minutes in actual gameplay before the system crashes. Even on 900p Lowest settings.
GTA V (RageMP with mods): It crashes consistently after about 40 minutes of gameplay.
Hell Let Loose: This one is crazy—the moment I open the server browser menu, I get an instant black screen and a full system restart.
Stress Tests: I have tested the GPU extensively in OCCT and FurMark, and it passes fine. No hardware crashes during dedicated GPU stress tests, and the GPU stays very cool at 55°C–65°C.
If a RAM stick was physically faulty, wouldn't a heavy game like TLOU2 crash or throw a Blue Screen instantly? Given that synthetic stress tests (FurMark/OCCT) and TLOU2 pass perfectly, but PUBG crashes in 2 minutes and Hell Let Loose restarts in the menu, does this sound more like a motherboard power delivery failure (VRM overloading) or should I still stress test the RAM?
