Hello, Kaleb N
Welcome to the Microsoft Community.
I'm sorry to hear about the problems you're experiencing with your computer game. It looks like you've already performed a lot of troubleshooting steps, but there are a few more things you can try:
- Windows Compatibility Mode:
Try running the game in compatibility mode. Right-click on the game's executable, go to Properties, and navigate to the Compatibility tab. Enable "Run this program in compatibility mode" and select an older version of Windows where the game is known to run.
- Disable unnecessary background processes:
Close any unnecessary background processes or applications that may consume system resources or conflict with the game. Use Task Manager to identify resource-intensive processes.
- Check for BIOS updates:
Ensure that the latest version of BIOS is installed on the motherboard. visit the manufacturer's website to check if there are updates available to resolve compatibility issues.
- Try Clean Boot: You can try Clean Boot to rule out the interference of third party software, you can refer to the following link:
How to perform a clean boot in Windows - Microsoft Support
Disclaimer: A “clean boot” starts Windows with a minimal set of drivers and startup programs. It helps to determine whether a background service is interfering with your game or program and to isolate the cause of a problem. These steps of "clean boot" might look complicated at first glance. However, to avoid any trouble for you, please follow them in order and step-by step so that it will help you get back on track.
5.If the above alternatives still don't work, we suggest you try to override the Win11 installation.
Download Windows 11 (microsoft.com)
Disclaimer: At this point, we have exhausted all troubleshooting and I recommend that we try to perform a clean install to get your computer back into a working condition. Please ensure that you backup any important data, including Documents, Pictures, Videos, and more. After that, you can find instructions on how to install Windows 10/11 in the following article by MVP Andre: How to: Perform a Custom Installation of Windows 11 and Windows 10 - Microsoft Community
