I'm experiencing some difficulties since a power outage occurred. My computer would start up and run for extended periods, but then it would suddenly stop without warning—sometimes just two minutes, sometimes up to eight hours. Once fully powered on, it turns off completely with no BSOD or error messages. The Event Viewer only shows the kernel power event ID 41, which doesn’t provide much clarity.

What I've tried:
- Swapped out the PSU, assuming the outage damaged it; the problem continued.
- The GPU performed well and didn't overheat, even during heavy games like Elden Ring.
- Changed power sources from a power strip to the wall outlet.
- Ran memtest and it passed.
- Conducted a CPU stress test without shutting down.
- Updated CMOS settings.
- Reassembled the PC and tested it on top of the motherboard.
- Enabled fast boot mode, as recommended by a friend.

I also received a spare motherboard for testing, but the issue still occurred. I’m taking my PC to a nearby technician as a final option. Please let me know what you think caused this problem—I’m really confused.

This:
"tested if it would still happen on the new motherboard, It still persisted."
Different motherboard but same PSU - correct? How old is the PSU? Specs?
What about the electrical outlet or circuit serving the PC's? Any surge protectors, power bars (did note you are using one), extension cords etc.?
Event Viewer is one tool. Another tool that is more end user friendly is Reliability History/Monitor.
Reliability History/Monitor presents a time line format that can reveal patterns.
Any other PSUs available? If so swap one of them in. Be sure to use only the power cables that come with the swapped in PSU.

Different motherboard yet identical PSU - is that possible? What is the age of the PSU? What are its specifications?
My previous PSU was just a generic one from my prebuilt 550w unit. The current PSU from Corsair CX650 is brand new.
Regarding the electrical outlet or circuit for the PC, do I have surge protectors or power bars? The powerbar includes a surge protector but lacks a UPS. The outlets in our house are standard two-prong ones, so I had to rely on the powerbar. I've tested it in various locations around the house.
If the technician can't resolve the problem, I'll check the Reliability History/Monitor.
I'll also search for alternative power supplies, but I'm skeptical since the PSU is brand new and the issue remains unchanged :/

Only the cables included with the new PSU were used.

Just a consideration... if you changed the mobos and it doesn't match the original, and you're using the same Windows version that ran the previous board, you might encounter problems that could affect your outcomes. Right now, it seems like there could be a power-related issue.

I wasn't able to reinstall Windows, I don't have a boot drive, and I'm worried the recovery process might stop if it had to reset the OS again after turning off while I was at the safeboot menu. I live in a remote area, and the only friend nearby doesn't have a boot drive I could use. The technician mentioned they're doing a fresh install. If that works, great! If not, I probably need to check for other power-related problems.
