Hello,promitheas

Welcome to Linux Community.

It sounds like you are experiencing some quality issues using Microsoft forums, could you please provide some details to let us assist you better:

1->General System Information: Could you provide some details about your PC's hardware specifications? Specifically, the processor, amount of RAM, and the graphics card you are using.

2->System File Check: When you say you automatically checked system files, did you use the built-in System File Checker (SFC) tool? Did it report any issues, or did it indicate that everything was fine?

3->Event Viewer: In the Event Manager, can you provide more specific details about the critical errors you see? For example, the exact error messages and any associated error codes.

Have you researched the specific error messages you found in the Event Manager (e.g., Application Error, Application Hang, Windows Error Reporting, DbxSvc, DistributedCOM, nvlddmkm)? Understanding these errors can often provide clues about the root cause of the problem. In the meantime, are you getting a blue screen on your device, and if it's convenient, try to see if a small dump file has been generated in the corresponding path, which you can upload and share with me-<Read small memory dump files - Windows Client | Microsoft Learn>

4->Cooling and Hardware Issues: Have you noticed any unusual temperature increases while running games or any other hardware-related issues like unusual fan noises or system freezes?

5->Rollback to Previous Windows Version: If the issue started immediately after switching to Windows 11, have you considered rolling back to your previous Windows version temporarily to see if the crashes persist?

The five points of detail above are intended to give me a better understanding of the situation so that I can give potential advice and solutions.

Best regards,
