Getting a black screen (no signal) when launching games

Basically the title. After launching a game, it will take about 10-15 seconds for the screen to go black and a popup from the monitor saying there's no signal. I can still hear and talk to people if I am in discord. At this point I have to shut down the computer and boot it up again. This basically only happens when I am trying to play games such as Fortnite and Overwatch.

Specs:
GPU: GTX 970
CPU: i7-3820 3.6ghz
PSU: 750W
RAM: 16GB DDR3
OS: Windows 8.0

My GPU temp doesn’t really go much higher than 65C. Tried to change DVI cable and tested in both fullscreen and windowed. The cable is connected to the GPU and there’s no adapter. I have tried to download the latest driver for my GPU but that didn't resolve the issue. Also I can still play games if I underclock using MSI afterburner. Im not sure if this means that my GPU is at fault or my PSU.

Tried to do this but I keep getting errors with the code: 0x00000070

Edit: Nevermind, got it to download. Problem still there unfortunately.

I am not overclocking, don't really have the experience/knowledge and confidence to do so. Nevermind the underclock comment, didn't really work anyway. Did download DDU and removed all the drivers and installed the new one but I keep getting the black screen.
