Why is Call of Duty Modern Warfare 3 stuck on loading screen?

Call of Duty Modern Warfare 3 is stuck on loading screen mainly due to outdated drivers and Windows-related services and processes. But they are not the only reason why this issue might happen. While I was researching the problem I have discovered that MW3 might also get stuck on loading screen due to:

  • System requirements: One of the most common reasons for encountering the MW3 infinite loading screen is not meeting the system requirements.
  • Corrupt Game Files: Sometimes, essential game files can become corrupted, causing the game to freeze during the loading process.
  • Insufficient Hardware: If your system doesn’t meet the game’s minimum requirements, you’ll likely run into loading and performance issues.
  • Overheating: Your CPU or GPU overheating can lead to performance issues, including freezing at the loading screen.
  • Game Updates: Sometimes, an incomplete or corrupted update can wreak havoc on the game’s ability to load properly.
  • Internet Connection and Server Issues: A poor or unstable internet connection can result in failed synchronizations between the MW3 client and the server, leading to hang-ups at the loading screen.

Hardware Solutions

This is always my last resort due to the fact that the hardware solutions take time and resources.

  5. Use a Cable
