I've been dealing with an issue on my home-built PC for a while now, and I'm at my wit's end trying to figure it out. For the last four years, everything has run smoothly, but it all started going downhill at the beginning of February. I have an AMD Ryzen 7 5800X CPU, an EVGA GeForce RTX 3070 Ti GPU, and an Asus ROG STRIX B550-F motherboard, among other solid components. I'm a streamer, and I rely on my PC heavily for my job. Recently, it started shutting down randomly—no blue screen or warning, just a sudden power loss. After checking the Windows Event Viewer, I keep seeing the error "Kernel power 41".
Sometimes it can run fine for 24-32 hours during test streams, but then it crashes a couple of times during an actual stream, and I have to do a hard restart. I've tested the PSU's rail lines, ran some stress tests, reduced RAM speeds, and tweaked some power settings, but nothing seems to help. The PSU is about 4-5 years old, and I'm trying another one soon, but if that doesn't solve the issue, I'm completely out of ideas. Any advice or suggestions would be incredibly appreciated!

If replacing the PSU doesn't work, consider these steps: First, monitor your temps during operation. Then run Memtest86 to test your RAM, check for malware using a solid tool like Malwarebytes, and if all else fails, perhaps reinstall Windows. You could also look into getting an uninterruptible power supply (UPS) to protect against power issues. Sometimes, just one bad power supply can cause major headaches.
It sounds like you're doing all the right things. Keep an eye on the new PSU; that's a common culprit for sudden power loss. If the issue persists, monitor the temperatures too—overheating can cause these shutdowns as well.
Have you checked the Event Viewer for details? Sometimes, critical temperature shutdowns can be logged there. Make sure everything is cooling well and consider running a memory test with something like Memtest86. Additionally, a good idea might be to check for malware, just in case!
