Thanks for checking and for sharing the screenshots.
First, I need to correct one part of my previous reply. I mistakenly told you to check Epic Online Services in services.msc. I confused the “EOS” name used by Easy Anti-Cheat with Epic Online Services.
So please ignore steps 3 and 4 from my previous message regarding Epic Online Services and its startup settings. I’m sorry for sending you down the wrong path.
In my own case, I checked the Easy Anti-Cheat logs and found that they specifically mentioned an old ASUS-related driver called CmUpx.sys that needed to be unloaded before the game could start. After I stopped and disabled the CmUpx service, Apex Legends started normally again.
However, your situation may have a different cause, since both Apex Legends and Fortnite are causing your entire PC to black-screen.
If possible, could you check your Easy Anti-Cheat logs and see whether they mention CmUpx.sys, another driver name, or any specific error?
If CmUpx.sys appears in the log, please let me know. I can then explain the exact steps I used to fix it.
Again, I’m sorry for the incorrect information in my previous reply, and thank you for taking the time to check everything and provide the screenshots.
