Mouse scrolls down automatically



I have a windows 10 computer (ALL-in-One desktop PC by ASUS) where I have scroll problem.

For example, when I open Add/Remove Program window and try to select "Microsoft  Office 365", it scrolls down automatically. I tried to move it up using Vertical Scroll bar or Page Up key on the keyboard, but it automatically scrolls down.

When I click "Windows Start" button on left bottom corner and try to select a program by placing my mouse in the vertical scroll bar, the computer starts moving down automatically and I lose control. I can't move it up becaues it comes down automatically.

However when I open File Explorer, for example, I navigate to C:\Windows\System32 folder, I can go up and down with a problem. Also when I open ESPN.com in Edge browser,  the mouse behaves normally.

When I open Excel blank sheet, it continuously scrolls to the right on its own.

So far, I checked Mouse settings in control panel and it had default settings just like any other computer. I tried Windows Update and tred to log in as a local administrator, but to no avail.

I thought it may be because of Wireless mouse and replaced it with wired mouse, but to no avail.

Can you help?

I had a mouse behaving like this. I replaced it with a new one and that behavior just stop. The mouse can be defective.

The USB mouse was brand new out of the box.

ASUS tech support suggested that USB dongle (for wireless mouse) removed from the computer. After that, the wired USB mouse is working normally.
