New graphic card but game flicker black screen and green glitch line
@great797 As a simple test, try playing in fullscreen mode on each monitor separately, with the other not plugged in. (Unplug whichever one you're not testing while your computer is off.) Let me know whether you see the same graphical glitches in either case.
Once you've finished, please also look for any crash dumps that happened during the testing. Open a File Explorer window and enter C:\Windows\Minidump in the address bar. Check the timestamps on the files you see, and if one matches your testing, right-click it and select Copy, then right-click your desktop and select Paste. From there you can upload it to the free filehosting site of your choice (Google Drive, Dropbox, etc.) and link it here.
If you don't see any such files, just let me know. Your dxdiag lists a couple of errors that are serious enough to look into, but since the dxdiag's info doesn't include timestamps, I have no way of knowing whether these are related to Sims 4.
