Noah's computer has an annoying popup that says running in compatibility mode can cause problems. Leo says it sounds like it could be malware or a downloaded tool that causes it. It's auto starting, so he'll need to get into the auto start menu to remove it.
First, he should go into "Add/Remove Programs" or "Programs/Features" and see if he can remove it there. Then he can try going into his startup utility. Leo recommends downloading Microsoft's AutoRuns. He should also teach his mom to only download from safe places.
