I recently built a new PC and have been troubleshooting various issues. Currently, I'm facing a frustrating problem where my PC restarts suddenly while I'm playing games. There are no blue screens or minidumps to analyze, and the only clue I have is an Event 41 Kernel Power log in the event viewer. I suspect it might be a hardware issue, so I logged my PC using HWInfo64 and attached my latest CSV log before the restart.
Here's my build:
- Motherboard: ASUS Tuf Gaming B850M Plus Wifi
- CPU: AMD Ryzen 7 9700x
- RAM: Corsair Vengeance 32GB 6000MHz CL30
- GPU: Asus Prime RTX 5070 Ti OC
- SSD: Samsung 990 Pro 2TB
- CPU cooler: Thermalright Peerless Assassin 120 Digital ARGB
- PSU: Corsair RM850X v3.1
- Case: Fractal Design Pop Mini Air
In BIOS, I've enabled EXPO 1 and set TDP to 105W. I previously dealt with a couple of issues related to the hypervisor errors, one linked to AMD PPM and another to the Nvidia driver, which I managed to resolve by tweaking the BIOS settings. I've also reseated the RAM, run Windows Memory Diagnostic, and ensured that my BIOS is up-to-date along with using the recommended AMD Chipset Driver from the motherboard website, despite it being a bit outdated. Any help or suggestions would be greatly appreciated!

It sounds like you've done a good amount of troubleshooting already! If none of these solutions work, consider trying a different wall outlet or power strip just to rule out electrical issues.
Have you checked your PSU ratings? An 850W unit usually should handle your setup fine, but if it’s faulty or not providing stable power, that could definitely cause restarts. You might want to run a power supply test to see if it’s delivering consistent power under load.
Your RAM could also be a factor here. Is it properly seated and running at the right frequency? Sometimes enabling EXPO can create compatibility issues. You may want to test the RAM sticks individually to rule out any faults.
Another thing to consider is the temperature. Make sure your CPU and GPU aren't overheating during gaming. It wouldn’t hurt to check the cooling setup and ensure the thermal paste on the CPU is applied correctly.
