Question Monitors go black, but PC stays on

Jul 27, 2020
I’ve been having this problem for weeks now and have tried everything. Randomly while gaming, but sometimes while just idle, my monitors (and this happened even with just one monitor) randomly powered off and said they lost signal and wouldn’t power on until I restarted the PC. The PC stayed on the whole time and I could hear audio too.

I’ve reinstalled my drivers, reapplied GPU thermal paste, reseated the GPU, switched to NVidia studio drivers, and even moved plugs around to different outlets but nothing has worked. Any help is appreciated! This is really annoying and I can provide any additional information.

I'm starting to believe it is a power supply issue, but I'm not sure because the actual PC itself stays on and running. I also hear a Windows disconnect sound which I think is my keyboard and mouse.

I'm having very similar issues. Monitors go black (still have the power light on but is orange like they are in sleep mode) Pc fans start running at 100% can still hear audio. My pc either restarts itself or have to hard restart it
