# Why Does Roblox Keep Crashing?

For some Roblox players, the game crashes when joining a game, and for others, it crashes once they enter the game. Why does Roblox keep crashing?

Below is a list of potential reasons for Roblox crashing on your PC:

  • Insufficient system hardware: Running Roblox requires a certain amount of system resources, including CPU, RAM, and disk space. If your computer resources are limited, the game may crash. You should take a quick look at its system requirements and see if your PC meets them.
  • Unnecessary background applications: These applications consume excessive memory and resources and may cause Roblox to crash.
  • Outdated or corrupted graphics drivers: Drivers that are not up to date or corrupted can cause compatibility issues and crashes.
  • Crashed game files: Crashed game files may cause the game to crash and you will need to reinstall the game or repair the game files to resolve the issue.
  • Corrupted Roblox cache: The Roblox cache stores temporary files that contain information about the app and help improve the experience. In some cases, the cache can become corrupted and cause Roblox to crash.
  • Windows security or firewall protection or any third-party antivirus program can prevent game files from functioning properly.
