I had a similar issue before where the cursor worked fine but the scroll wheel just stopped responding. In my case, it turned out not to be anything major, just a mix of settings and wear.

A few things you can try:

– First, check if scrolling doesn’t work everywhere (browser, files, settings). If it fails in all apps, it’s likely system or hardware-related.
– Go to your mouse settings and make sure scrolling is actually enabled and not set to something like 0 lines.
– Try updating or reinstalling the mouse driver from Device Manager — that fixed it for me once.
– Plug the mouse into a different USB port or test it on another computer. This helps confirm if it’s the mouse itself.
– Also, clean the scroll wheel — dust buildup can stop it from registering movement.

In my case, the mouse worked fine on another system, so it was a driver issue. But if yours doesn’t scroll anywhere, the wheel might just be worn out and need replacement.
