Windows 10: PC scrolling up and down by itself

A few days ago, my desktop suddenly started scrolling up and down by itself. It has gotten bad enough that my computer is nearly unusable as it keeps clicking out of text fields, interrupting games, etc. Sometimes the mouse scroll wheel won't even respond.


So far, I have tried:

- Switching mice (both mice have done the same thing)

- Unplugging mouse and keyboard

- Disabling page up/down keys on the keyboard

- Installing windows updates

- Running a virus scan (nothing)

- Uninstalling and reinstalling mouse and tablet monitor drivers

- Restarting numerous times

- Updating apps

- Running a system scan (also nothing)


Absolutely nothing has worked. As far as I know, there were no updates or anything that led up to this. I don't have any devices such as a game controller that could be causing this. None of the keyboard keys are sticking, either. Any help would be appreciated.

PC Build Steps

Ok just because I like steps i am going to create some steps. Please give me the stamp of approval/disapproval

• Install system in case
  • Remember to connect SSD and optical to same SATA ports on motherboard
• Turn on PC
• setup HDD
• run blend test in prime95 for 30-60 min
  • run realtemp at the same time

• While in Prime95 test
  • if CPU goes above 70c in RealTemp, I have a leaky CPU
  • if my system locks up or blue screens, there is an instability in the system somewhere
  • if my system does not lock up or blue screen, my CPU is not damaged and I am in the clear!

What do you guys think??
