So I built this pc myself and it was working fine for more than 2 years, but now for the past few months it restarts randomly during any task. I checked the event viewer and I'm getting Kernal-Power error, event ID 41.

I've replaced and swapped out just about every single part so now I'm at a loss. I can give system specs if needed but first I'll run through what I've done for troubleshooting so far. The first thing I thought to do was get a new power supply, I need a spare one so I had reasons to buy a new one. Then after that didn't work I tried using 1 of my 2 sticks of ram in different slots(I used both one at a time) but it still restarted. I also ran memtest and it look good, no errors. I then tried a spare gpu and that didn't work. I then bought a whole new HDD and reinstalled windows onto it, all while unplugging the other HDD and SSD. After fresh install on new HDD I still had the restarting. After that I bought a whole new mobo and cpu and installed those, and had very good luck for over a week. Last night and today it starting restarting again so now I'm back to square one. I've essentially swapped out every part other than ram, and unplugged nearly every cord or wire when I put the new mobo in.

My pc literally restarted while I was typing this, ugh. So I checked Windows updates and saw that there was an update around the time I started crashing again, so maybe it was that. I'm going to try uninstalling it and seeing what happens next. The issue for me is that the crashes are seemingly random and I can't force a crash with a stress test or the likes, so I just play games or browse the web and "hope" for one. This sometimes takes all day and then it's back to troubleshooting.

EDIT: The windows update I was trying to uninstall was KB4532693, but it wasn't uninstalling so I checked for new updates and there was another one that took its place. The new one is KB4549951. Let's hope that was the issue but I'm really not all that hopeful.

Edit2: Don't think that it's Windows.

Did you install any tuning or driver updater tools?

Any 3rd party antivirus, firewall?

I am going to check these things, I would also like to add that the only times that my pc ran for at least a week without restarting were when I updated my bios, and after I changed to the new mobo/cpu. My pc started restarting about a week after I updated my bios on my last mobo, but do you think something in the bios, like the vcore voltage, is the underlying issue here?

I checked DISM and that came back good no errors. I did do some updater tools and all drivers are up to date. I uninstalled all 3rd party antivirus so I'm running just windows defender for now. I'll look into user benchmark(I'm not on my main pc because the crashing prevents me from enjoying my day off, I'll get to that later)

Kernal-Power error usually means low CPU Voltage at that time. See if your BIOS supports LLC or positive voltage offset.
What would the chances that my AORUS GA-Z270X-Gaming K7 mobo and my i7-7700k are having the same vcore/general issues as my new Gigabyte Z390 UD mobo and my i7-9700k setup? If it were vcore and it was bios, wouldn't it be strange for the problem to persist with all new parts? Genuinely curious
