Question Random 2 second blackscreens and no idea why...

[Crito4C]

Hi!
I have ~2 second blackscreens, exclusively when gaming, not during benchmarks. They happen roughly every 5-10 Minutes and are extremely annoying, especially in competitive games as you can imagine.
Since the issue first appeared I upgraded to a new graphics card twice and bought a new monitor, so it can't really be those. I removed my four ram bars individually, no setting fixed the issue.
I have no idea what it is or what to do, other than buying a new motherboard which would kinda suck..

This is the setup:

Windows 10
acer KG271U 144hz WQHD monitor
MSI Gaming X gtx 1070
ASUS H97-pro gamer
i7-4790k 4x4ghz (4.5ghz turbo)
16GB Kingston Fury DDR3 SDRAM
bequiet straight power 10 600w

I hope someone can help!

I used to have the same prob but it just went away by its own.Though it didnt happen every 5-10 mins but 2-3 times a month.The only thing i did was to unplug the monitor from power and replug it.Also i made sure the hdmi and power cables (of the monitor) werent touching any other cables.
