Mouse scroll wheel jumping or skipping when you scroll
Your scroll wheel is clogged with dust or debris, or the mechanical sensor inside is worn out. Try cleaning around the scroll wheel with a dry cotton swab or compressed air first. That fixes it for most users. If cleaning doesn't work, the mouse likely needs replacing.
Your scroll wheel has a tiny sensor inside that counts how many times you turn it and tells your computer how far to scroll. When dust, dirt, or hair gets stuck in there, or when the sensor wears out, it sends wrong signals and your scrolling jumps around. We'll start by cleaning it, and if that doesn't work, we can test whether the mouse hardware is failing.
- ✓Have a web browser or document with scrollable content open so you can test the scroll wheel
- ✓Have a dry cotton swab and compressed air ready for cleaning
- ✓If it's a wireless mouse, have fresh batteries available

Skip, I just want a technicianCommon mistakes to avoid
- Using a wet cloth to clean the scroll wheel. Moisture can damage the sensor inside; always use a dry swab or compressed air
- Not checking the battery level in a wireless mouse first. Weak batteries cause erratic scrolling
- Assuming the mouse is broken when dirty scroll wheels cause most of this problem. Cleaning fixes it completely
- Ignoring that the problem can be in Windows Settings. Check the mouse sensitivity settings before deciding the hardware is broken
