Hello. One day, on July 30, I downloaded ThrottleStop to undervolt my CPU. I undervolted it too much, and my laptop crashed. I opened my laptop to find out all my browsers except Google were gone, but all my history and Gmail information was gone from google. I'm like "Ok, I can just put back everything to how it was before." So 2 weeks later, I restarted my laptop. EVERYTHING i downloaded in that 2 week time period was gone, and all my downloaded things (On and before July 30) was moved into the Download section of my Users file in C:. Everything resetted to how it was on July 30, and my browser history was gone, etc. I do not know how to fix this, and have tried various methods (reinstalling Windows Updates, putting my voltage to normal capacity.) How do I fix this? This is a really annoying bug and really makes me wanna break my keyboard or mouse. Someone help please?
(Also, everything from My desktop is removed, my Background turns into the Normal windows 10 background, but my passwords stay the same.)
Edit: This happens after every single restart. I tested it by download some other things, then restarting my laptop, and then they are also deleted.
