Why when I use the scroll wheel it zooms?
You're likely to come across this issue if the Ctrl key is stuck. That's because pressing Ctrl and using the mouse wheel usually zooms in or out on a page. So, just take a look at the Ctrl key and ensure that it's not stuck or damaged.
Why is my mouse wheel not scrolling smoothly?
The most typical causes of a mouse that will not scroll are two difficulties. The first is that dust and grime clog the mouse wheel, causing mechanical problems. The second issue is that wireless mice have poor battery life.
