If reinstalling windows didn’t fix the issue then you most likely have a hardware issue. You could always make a linux live USB and see if that works. The live USB won’t touch your HDD so if the HDD is the problem you won’t know until after you’ve installed linux.

Before you do that download a program like hwinfo and look at your temps. Specifically CPU temp. Somewhere towards the bottom it will tell you stats about your HDD as well and it may include what SMART thinks your HDD’s health is.
