Not BSOD but crashes/restarts every 20 mins to an hour.

My PC keeps crashing over and over again usually between 20 minutes to an hour or so. Just updated to windows 11 to see if it solved the issue.

I built my system pretty much a year ago to the date. Its ran great the whole time never had an issue with it. Built it myself. Over the last two weeks it has randomly started crashing on me. Someone said it might be armory crate, tried removing that to no avail. Saw that I had an error report on it but didnt look properly at the date, it was from a year ago.
I really wanna refrain from having to do a fresh install (being that nothing has changed on it I feel like it may be something else.) I dropped my overclock and it still kept happening. It happens randomly if im just watching youtube, playing a game, not doing anything, doesn't seem to have any rime or reason to the length of time its been on/doing tasks.

Windows 11(now after trying to solve by upgrading from 10)
x64
Windows 10 originally Full retail
1 year old hardware and os besides the upgrade to 11 today
i5 12600k (slightly overclocked but have tried changing it or removing and nothing)
RTX 3070ti
asus z690mb
AriesGames 800w
Home built system
32gb tforce ram
Desktop

Idk where to go from here on finding the culprit or trying to diagnose the issue.

What do the temperatures look like? HWMonitor is a handy tool for that.

Temps are very stable according to AI suite. Not getting above 43 but mostly in low 30s.

I don't see anything in either your System or Application logs that might precipitate these crashes, and I don;t see any drivers you have that make me sit up and take notice either. Since it happens after 20 minutes or so I'm wondering whether it could be PSU related. Is that 800W PSU beefy enough to handle any power spikes you might get under heavy load? Hardware isn't my thing, so I'm just putting this out there. This feels more like hardware than software to me....
