Question Dragon Quest 11 and other games crash, monitor displayport-NO SIGNAL

[starflame34]

Recently, I've been having trouble playing certain games on my PC. Specifically Dragon Quest 11 and Rocket League. For whatever reason, my monitor randomly goes black and says "Displayport-NO SIGNAL". I've tried EVERYTHING to fix this, from cleaning out my PC, unplugging everything, fresh re-installs of the games and drivers, playing in Windowed mode with different graphic settings, switching cables, and nothing!

The only thing I noticed is that these games both run on Unreal Engine, but I've never had trouble with Rocket League for the past 3 years and my setup is still the same. Any other game works fine, it's just these 2 that haven't been working. I already submitted a ticket to Unreal Engine site, but God knows when they'll get back to me.

I have looked high and low for a solution and can't find one. Please, SOMEONE help!

-OS: Windows 8.1 64-bit

If were talking about the graphics card, temps didn't go above 58*C

UPDATE: So yeah, now this is happening to ALL games I'm playing, not just those 2. Sometimes the fans will also start going crazy, but not always.
