Monitors Suddenly Losing Signal

HP Recommended
OMEN Obelisk Desktop
Microsoft Windows 10 (64-bit)

So it happened twice now (I think today and a few days ago) that my monitors would suddenly lose signal. Both time it happened at around 1:30AM (I was gaming during both occasions) so in the early morning and both of my connected monitors (one HDMI and one Display port) would all of a sudden lose signal and go black screen (they are still powered on), and my audio would cut off seconds after that (connected through USB). 


However, I have a set of razer accessories with dynamic lights and those lights work as usual after the monitors lose connection and audio is cut off. I have tried reconnecting the cables connecting the monitors to the computer, the monitor recognizes it has been plugged in and switches to the display port channel, but there is no incoming signal and the monitor remains black.


Holding down the power button and manually rebooting seems to resolve this issue (apparently temporarily), and both times after reboot Windows had some sort of update (it popped up several times before the incident to remind me to update but i just clicked the arrow that makes the message disappear). I have waited at least a couple of minutes before i manually restarted the computer (mostly trying to reconnect the connections).  I suspected this was the computer automatically updating outside of my active hours (which, when i later checked was automatically set to during the day). However, in my update history there was no updated installed at the time of the monitors turning off, and when I restarted to update later there was an actual screen with the spinning circle showing the words "restarting" and this was not the case when my monitors just went black.


I was wondering if anyone can figure out what is actually going on and let me know if this is a problem to be concerned about. Thanks a ton.

Unless I don't understand, it's hard to know what happened.
So the computer works now?
A loss of display, if it was playing with two more monitors, could be an overheating of the graphics card!
An update could be the case, but indeed if no trace of the maj, it remains difficult to know!
After that there could be some hardware problem!
I advise you to test for the moment the operation with a single screen.
To check if not a problem with the HP system:
