I didn't have this problems until Windows decided to force/trick me into updating to Windows 10. Was just in testing Sims 4 and it seemed to work then went into build mode and the blackness happened. Not just to this program, but everything. Nothing would show, no other window or program had any light, just blackness. I tried the windowed mode fix and at first glance it seems to work. It is currently working. I hope it stays that way. I can live with windowed mode.
Make sure all your drivers are updated with Win 10.
You might need have to reinstall Win 10 (instead of just upgrading) if you have the issue with all your programs
