Scrolling Uncontrollably

My computer seems to scrolling uncontrollably, but not scrolling at the same time. Here are the syptoms:

1. It only scroll uncontrollably on the taskbar and address bar and tabs on search engine ( and similar program that have button on top like ms word),
2. It doesn't scroll up down on the page itself, I can still scroll on the page normally,
3. This problem occur randomly, sometime I can use my laptop normally sometime the random scroll make me unable to use the computer,
4. It can also be noted that sometimes when I write on the keyboard, it jumps to address bar (similar properties) or tabs (similar properties), and
5. When pressing "a" the scrolling stops, but I don't know why

Please help me resolve this issue...

 

Cursor scrolls uncontrollably.

This is a recent happening. I have no idea how it came about. I start the computer, and as soon as I place the cursor to type (applications, search boxes, etc.) it scrolls by itself to whatever boundary the placement has. I looked this up and found this discussion. Uncontrollable scrolling on windows 10 - December 2019 - Forums - CNET
Other than restore or reset, I've done several of the "fixes" listed. (Latest drivers, etc.) The only thing that worked is logging out, and back in. But this fix is temporary. Restarting the machine brings it back, and I have to Log Out/In again to stop it. This makes no sense. Any ideas how to rectify this short of reinstalling windows?

Xbox one auto scrolling downwards

Hi samlloyd98,

Let's try to isolate this issue so that we could figure out what's causing your Xbox One from automatically scrolling downward. Kindly provide us the following information:

• May I know when did you notice this issue?
• Can you tell us if you recently updated your Xbox One?
• Does the issue occur even if the controllers are not connected to your Xbox One?

In the meantime, I recommend that you power cycle your Xbox One console by performing the following steps:

• Turn off the Xbox One console by pressing the Xbox button
  on the front of the console for about 10 seconds until it shuts down completely.
• Unplug the console's power cable. Wait 10 seconds.
  Important Be sure to wait 10 seconds. This step resets the power supply.
  
• Plug the console power cable back in.
• Press the Xbox buttonon your console to turn on the Xbox One.

We look forward to your reply.
