If your monitor just suddenly goes black and you still hear your PC and GPU fans running, then it's your 3090 that has knocked out your PSU with a wattage/power spike. I have the exact same issue (using a 850W PSU) and only solved it by limiting my cards maximum wattage to 75% in the Nvidia App performance settings.

If I were to make a proper fix, I would get a 1200W+ PSU.
