Windows 10: Why does my scroll bar move on it's own?

I've been having a major problem. I cannot move down to view anything because the scroll bar automatically moves back up anytime I try to move down.I already reset Windows 10 and waited hours and hours to reinstall windows and it's still happening. I even attempted to uninstall the last "Update", but because of the scrolling I could not get to the bottom the list to uninstall the last update.I'm at my wits end. I'm unable to do almost anything on my desktop anymore. This just began happening yesterday, but it's been horrible. It's basically made my using my computer next to useless.

TPU review scroll bar

I was wondering if there was any specific reason the buttons to scroll down the list of reviews was stuck in the bottom left-hand corner? Whenever I want to read reviews, I always have to move my cursor and aim it at a small arrow that scrolls the reviews... I'd suggest that instead of making the arrows small and in a corner, it would be better placed to the sides of the review bar.

Something like this (yes, I know it's crappy but it took 5min to make):

Scroll bars

I am having problems with lists that have scroll bars. Best example is the navigation pane of File Explorer. If a vertical scroll bar is present the navigation panel will jitter (flicker)! If I expand file explorer vertically so that the scroll bar disappears
the jitter will stop. Another good example is the list of Apps and features - my list is large and so the window cannot be vertically expanded so that the scroll bar disappears. This happens also in several of my apps. And, it also happens in my browser
searches. The jitter is so severe that I cannot highlight an entry to modify it. Any help?
