Assuming that you also have an FPS drop and your Network graph shows no packet losses and looks similar to the one provided in the first post, that indeed could be a performance-related issue, CyberHero. Please, refer to my previous message and see if the steps suggested there help you.
As you mentioned a gaming PC, check the pre-installed programs especially (there is often a number of them on gaming laptops).
If there are no improvements, please do not add your link to DxDiag and MSinfo file to this thread but create a new one instead.
A crash can have several different causes and mixing 2 potentially unrelated issues in one thread can create a lot of confusion.
Please open your own thread, describe what happens, what troubleshooting steps you already tried, and copy there the links to your diagnostic files. We’ll be happy to look into it for you!
Thank you!
