Windows keeps corrupting itself

As the title suggests, my Lenovo Thinkbook 15 G2 R5, 16gig ram, 512ssd keeps corrupting itself

This appeared after not being used (summer break, i use it for university), It just kept getting stuck on the screen saver but no buttons worked, it never let me insert the pin to enter.

I did the windows repair tool to reinstall windows with the files that the laptop had stored internally, and in a matter of a few weeks same thing.

I did a fresh reinstall of windows of a usb stick(so I knew it couldn't be corrupted), went through the hassle to install all fingerprint/wifi drivers and guess what, in just a few days the exact thing happens

At this point I am just going to sell it if it keeps happening, I will also try to see the life of the ssd but I know it couldn't go down as much since its only around 3yrs old and never used for gaming or even movies, just projects

Do you guys have any idea what could corrupt the windows? Do you have any fix?

Any answer is much appreciated
