Monitors suddenly goes black
Naweo:
It keeps happenning frequently again.
It usually happens right after turning on PC, and all 4 monitors goes "No signal detected" and I am forced to restart.
Any thoughts?
I did update nvidia drivers

Free fixes...
Try fewer screens, swap cables, see if there is a firmware or driver available from the manufacturers (screens have drivers and firmware, too!).
More screens can cause all sorts of weird things, 2 screens on my Intel gpu works fine, but if I add a third I can't see anything until the OS reaches desktop. Not even bios shows up. Disconnect one screen everything's fine. On my 1070, no issues with 3 screens.
Non free possibilities...
Your cables may be garbage and messing up the frequency/interference or your GPU may not like that many screens going through those specific ports, if you have any adapters, swap one cable to a different type port and see what it does.

Mostly off-topic, but how does a cable that has worked fine for 2 years suddenly stop working properly? There are no moving parts and they seem to be completely static.

and
Vibration leading to breaks
New outside interference
Component drift may finally reach a point all of the above reaches critical mass.
