Hey everyone! I'm having a frustrating issue with my computer that keeps shutting down on its own. It seems to happen most often right after I start it up, usually shortly after the Windows logo appears. I've already wiped the system and reinstalled Windows, plus reset my motherboard to the optimized defaults, but nothing's working. I did enable memory dump, but since the computer just shuts down and doesn't crash, there's nothing useful there. I noticed an error related to Hyper-V in the event viewer, but that went away after I disabled Hyper-V. Despite that, it's still shutting down. What should I check first? Should I look at the PSU, motherboard, or CPU? Any other tips besides just swapping out parts?

When it shuts down, does it completely power off, or do the fans and lights stay on? It might help clarify what’s happening.
You might want to check your hard drive first. But don’t forget to test the memory too, that’s a crucial step!
I can run MemTest86 again, but I'm worried it won't stay on long enough to test. I thought memory issues usually lead to blue screens instead of complete shutdowns. Wouldn’t that also show up in the logs?

It completely shuts down every time! Then it just reboots again.
