Hey everyone, I'm struggling with random hard shutdowns on my system and I could really use some help figuring this out. Here are my specs:
- **CPU:** Ryzen 9 7900X
- **GPU:** XFX MERC319 RX 6950XT
- **Motherboard:** ASUS ROG Strix B650E-F Gaming WiFi
- **RAM:** 32GB (2x16GB) G.Skill DDR5 6000 CL36
- **PSU:** Corsair RM1000x (original), swapped to another Corsair 1000W for testing
- **Storage:** Samsung 980 Pro NVMe + 256GB SATA SSD
- **Cooler:** Arctic Liquid Freezer II 360
- **OS:** Windows 11 Pro (24H2)
The problem is that my PC randomly shuts down and restarts without a BSOD, and the Event Viewer shows a Kernel-Power 41 error. This can happen weeks or months apart but it's consistent when under GPU load.
I've done some testing:
- Stressed the CPU alone and it was stable
- Any GPU-related stress test causes it to shut down within minutes
- Combined tests also lead to shutdowns in about 2 minutes
- If I remove the GPU, there are no shutdowns at all.
Here's what I've tried so far:
- Updated BIOS, loaded optimized defaults
- Tuned RAM settings
- Updated all drivers and performed a clean Windows install
- Swapped the PSU
- Checked all cable connections and ran various stress tests
- Monitored temps (CPU hits ~95-99°C under full load, but that's normal for the 7900X).
I'm hoping for guidance on what to do next!

Have you made sure to refactor your system BIOS settings carefully? Making changes there can sometimes lead to issues if things aren't optimized well. Also, double-check that all your drivers are up to date.
Have you tried switching your power outlet or using a different surge protector? Sometimes the issue might originate from unstable power supply at the socket.
It sounds like you might need to check for dump files to get to the bottom of this. If you can boot into Windows, try looking in C:WindowsMinidump for any crash logs. If you find them, zip them up and share, as they can really help with diagnosis.
I actually tried three different outlets and surge protectors, but no luck.
