Even with good posture and taking breaks from the computer, Alex could still be at risk for the following computer-related health problems:
- musculoskeletal problems: Even with good posture, prolonged sitting and repetitive movements can still lead to discomfort or strain in muscles and joints.
- vision problems: Extended screen time can lead to digital eye strain or computer vision syndrome, causing discomfort and vision-related issues.
- headaches: Eye strain, tension in muscles, or poor ergonomics can contribute to headaches, even if posture is good.

Thus, the correct answers are:
- musculoskeletal problems
- vision problems
- headaches
