[2021] EU4 Graphic card problem (code 43)

It does not happen in HOI4, specifically?

Has EU4 ever worked on this machine? Or never yet?


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.

Please attach here your Documents/Paradox Interactive/EU4/settings.txt and pdx_settings.txt .
From your Documents/Paradox Interactive/EU4/logs/ folder, attach here system.log , error.log .  

No evidence of a game problem in any of those files, sadly. Windows is not fully up to date but obviously that was the case before this happened.

There are several LiveKernelEvent entries in dxdiag there, which means the machine was forced down in some way. Were those related to this game or something else?


Let's try a full **clean** re-install:

- move any valued save games elsewhere
- "uninstall" in Steam-EU4
- manually delete both the Steam/SteamApps/common/EU4 AND Documents/Paradox Interactive/EU4 folders
- re-install game in Steam, run a Steam Verify when done.
- add EU4.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list.
- start the game with no mods active and test

In particular make sure there are no files or folders left under either the Steam EU4 or Documents EU4 locations, before installing again.  

According to MS it may be a hardware fault:

We can try a clean reinstall of the drivers though:
- uninstall the Intel and nVidia drivers, plus all other nVidia software
- reboot
- install the latest Intel video driver from here:

Good luck with that!
