I've moved you into your own thread , as this is an unrelated issue.
Next time you get a BSoD , record the text on that screen for us please. And/or check them out in your Windows Event Viewer.
DXDIAG is a program you run from the Windows search box on the task bar. After running it will open a window and start collecting info with a progress bar in the lower-left corner. When it completes click the 'save all information' button and save it to a file then attach that file here. IF dxdiag.txt fails to attach here, rename it to dxdiag.log , or zip it up.
Please attach here your Documents/Paradox Interactive/Europa Universalis IV/settings.txt and pdx_settings.txt .
From your Documents/Paradox Interactive/Europa Universalis IV/logs/ folder, attach here system.log
