Question Monitor black screen ?

[Frozenjello_7]

Hi, I am running a 3 monitor setup, and I'm having trouble with one of my monitors. It does this every blue moon where one monitor goes black screen, and it will not "Extend desktop to this display." I have tried switching cables, restarting the PC, power cords, I checked that the monitor is on, but nothing works. I know some signal must be going because when I turn on my PC it turns on the monitor and it says "DisplayPort - NO SIGNAL" to all monitors for a second, then they turn on windows. This particular monitor never does, it continues to say NO SIGNAL.

I checked drivers, and when I click extend this display, my computer freezes like its trying but just cant. Like freezes to the point that nothing works, nothing moves on the screen, my rgb stops working on my keyboard, mouse wont move. I am using a GTX 1080ti and my monitors are ASUS VG248QE. Not that I think it matters, but I have a Ryzen 5900x, water cooled, 32gb corsair vengeance ram, and over 6tb of HHD and m.2 storage.

Make and model of your PSU and it's age? Have you tried using DDU to uninstall (all)your GPU drivers? You're advised to reinstall the latest GPU driver in an elevated command, i.e, Right click installer>Run as Administrator, once you've cleared your platform of the prior drivers using DDU.

Make and model of your motherboard? BIOS version for said motherboard? If you're on Windows 10, what version(not edition) of the OS are you working with?

Power supply is a great question, not sure but i believe it was a evga nova G2 850 watt. I have the monitos plugged into a UPS that can run the whole system for like 10-20 min if the power goes out. Motherboard is a MAG x570 TOMAHAWK wifi, system info says SMBIOS version 2.8. Im on windows 10 home. The issue comes and goes every blue moon and can last as along as 30 min or a week. I mess around with the power cords and nothing changes, but if I unplug the black monitor and wait like a day and really shove it in the port, there is a slightly increased chance it will work. Again, it really is chance though, when i swap with other power cords from the other monitors, it changes nothing.
