Portal 2 may not start on your PC due to various issues, such as outdated graphics drivers, insufficient system requirements, or conflicts with background applications. Ensure your operating system and drivers are up to date, and verify that your hardware meets the game's requirements. Additionally, try running the game as an administrator or verifying the game files through Steam to fix any corrupted files. If problems persist, check online forums for specific troubleshooting steps related to your setup.
