A user's mouse appears to be jumping around the screen. Which of the following will MOST likely to fix the issue?

While outdated drivers can cause issues, physical obstruction of the sensor is a more common and direct cause for erratic cursor movement than driver problems.

For optical mice, dirt, dust, or debris on the sensor or the mouse pad can interfere with the mouse's ability to track movement accurately, leading to erratic cursor behavior. Cleaning the optical sensor and ensuring a clean surface for the mouse to operate on usually resolves this issue.

Using a different USB port might help if the current port is faulty, but it is less likely to cause a 'jumping' cursor than a dirty sensor, which directly impacts tracking.

Restarting the computer can resolve temporary software glitches, but it is unlikely to fix a persistent hardware issue like a dirty mouse sensor.
