I updated the motherboard drivers with manufacturer drivers (they were all windows default drivers) and she played the game for over 3 hours tonight before it finally white screened on her. I used the disk that came with the computer so I'm going to try to download all the latest and greatest drivers. Is the SIMS 4 a 32 bit app as well? That is the game she is playing, not SIMS 3. If this doesn't work to her satisfaction we'll just send this computer back. I can update the video card in her old system from a Nvidia GT 200 to a GT 1030 for under a hundred bucks, roll it back to Windows 7 (game ran fine under Windows 7 with the GT 200 card, problems didn't start till we upgraded to Windows 10) and hopefully all will be good. That will net me about a thousand bucks back in my pocket. I'll post another DXDIAG and an update tomorrow when I get home from work. Thanks for the help.
