 Hi aditya,


Thank you for posting your question in Microsoft Community!


I understand that you are unable to play halo 2 on your computer. I will try to help you with this.


Please check if you have sufficient graphics memory. Also check the requirement specifications for Halo 2 game and see if it matches with the configuration of your computer.



 Apart from this, you can try updating the graphics drivers.


Perform clean boot to check whether it is a software conflict issue.

Putting your system in clean boot state helps in identifying if any third party applications or startup items are causing the issue. If yes, you may have to contact the program manufacturer for any updates or uninstall and re-install the program.

Clean boot:


Note: After clean boot troubleshooting step, follow the “Steps to configure Windows to use a Normal startup state” in the provided link to return your computer to Normal startup mode.



If the issue still persists then you may post your question in the gaming forum.
