Out of Range/No signal detected when launching certain games.

[JexusMaybe]

Hey, I was previously having a problem with my PC where it would simply crash when I would try to play a intensive game or be in a somewhat graphically intensive part of a game; but sometimes it would only be the monitor.
I have since upgraded my motherboard, CPU and ram and now I am only getting the monitor problem.
When I try to play a "demanding" game or turn the settings up on a game my monitor will simply go black and display one of the two messages: Out of Range or No signal detected.

SPECS:
AMD Ryzen 2700x - 3.7GHZ (stock)
MSI X470 GAMING PLUS
HyperX FURY 16GB (8x2) 2400MHZ
EVGA 6GB 980ti SC
EVGA 650G
BenQ XL2420T (1920x1080@120Hz)

When launching WoW, PUBG and Overwatch my monitor will turn black and say it it out of range. I have tried using another monitor with lower refresh rate and changed from using DVI to DP.

Any information if greatly appreciated.
