I have a brand new AMD Ryzen 9 5900X with an RTX 3080 running Windows 11 Pro. The computer runs pretty much 24/7. Every morning I wake up to the computer being in its expected idle state (running, monitors on sleep). I hit some keys on the keyboard or move the mouse to wake it up. The monitors come alive (lights turn on, display lights up), but they only show a black screen. The computer will still respond to ping requests over the network, but anything else is unresponsive (remote desktop, accessing shares, ...).
I have already disconnected all hard disks except for the system SSD (nvme) and all external devices except for displays, keyboard and mouse. The event logs aren't showing anything at all.
Does anyone have any suggestions as what I could try to figure out what is the problem?
