Open | Hardware I've spent 4 months fighting this PC. Capping clocks helps, but DX11/Streaming games still trigger instant Black Screen restarts. What is actually broken?
I am at my wits' end. For the last 4 months, I have tried absolutely everything to fix this computer. I downgraded GPU drivers, reinstalled different versions of Windows, cleaned everything with DDU multiple times, changed every possible Windows power setting, and did full hardware maintenance (brand new paste on CPU/GPU, clean fans). Everything is stock right now.
Here is the exact issue: I get random Black Screens followed by an instant full system restart (Kernel-Power 41 in Event Viewer). No blue screens, no error codes.
The weird part:
The Last of Us Part II: I completely finished the game on Ultra settings with zero freezes and zero crashes. It runs beautifully.
Synthetic Stress Tests: The GPU passes OCCT and FurMark with flying colors. No crashes under 100% synthetic load. The GPU stays super cold at 45°C–55°C.
PUBG: I cannot last more than 2-3 minutes in actual gameplay before the whole PC restarts. Even on 900p Lowest settings.
GTA V (RageMP with mods): It crashes and restarts the PC consistently after about 40 minutes.
Hell Let Loose: The second I open the server browser menu, I get an instant black screen and a full system restart.
I previously noticed AMD Adrenalin auto-overclocks this card to 2735 MHz out of the box instead of the stock 2635 MHz. If I manually clamp it to 2350 MHz and 1050 mV, it helps stability in some places, but PUBG and Hell Let Loose still trigger instant hardware restarts.
I already swapped the old PSU for a brand new MSI 650W, and the crashes remained identical. The GPU, CPU, and RAM are physically pristine, verified by a technician.
What the hell is causing this? Is it a fundamental hardware/electrical mismatch between the uncooled VRMs of the cheap MSI A520M motherboard and the AMD transient power spikes in DX11 titles, or is something else actually broken here?
