Windows 10 hard locks itself randomly!

[PatXioPC]

So I just swapped my ryzen 1600X with a 2700X, And the board I'm using is the x470-F from ASUS ROG. But immediately, going to the BIOS showed me the AUTO AI TWEAKER had the vcore set to 1.49V which was ridiculous so I bumped it down to 1.34V and booted into windows.

And after that, I ran aida64 and stressed the CPU, FPU, Cache, and memory about an hour or so, then when it passed, I closed the application but after a while, my windows hard froze, so I had to power recycle it. Then on my reboot, I stressed with prime95 both Small and large FFTs, and still, there was no hardware error detected, but once I end the task, it randomly freezes. This way, I had to install windows several times and was very shocked to see each attempt fail, yet no hardware failure, no detection in the POST CHECK LED Panel of my mobo. So now I've got what I may have done wrong, I was stupid enough to not increase the voltage a little bit and test. I did so, made it 1.35V from 1.34V, and I have tested with both syntactic and real-world torture runs to my system, did play YouTube videos in 8k (because weirdly enough, the crash was when I ran chrome and watching videos). I did every trick in the book I knew to see it fail again like heavy rendering, encoded 12 h.264 4K videos, and compression of 18gig files using 7zip. Playing 2 8k videos simultaneously and so on. And frankly, it didn't fail. What do you guys think, is it enough time to say that my system will be alright?
