Hi Everyone, I have quite the problem that I can't quite solve. I left town for about 10 days and left my computer on sleep/hibernate. Normally, my computer wakes when I press a keyboard / move mouse. Instead of moving the mouse, I pressed the power button thinking that it was off, and it seemed to "wake up", but there was no display output. I tried holding the power button, but it doesn't turn off the computer. No matter what I tried, I couldn't get the system to display anything .
My specs are as follows:
Motherboard: Asus B450-I
PSU: Corsair SF750
CPU: Ryzen 7 3800x
CPU Cooler: EK RGB 240mm Radiator
RAM: 2x16GB Crucial Ballistix 3600
GPU: Nvidia 3080 Founders Edition
Case: Formd T1 w/ Riser cable
OS: Windows 10 Professional
I've had this system for almost a year and have had no problems at all (I transplanted to a new case and replaced the graphics card in that time). Now, I cannot get it to display any output. I tried different cables, different monitors, another graphics card (an old Matrix 980GTX) and nothing works. I also tried removing the ram and don't get any POST beeps.
I also tried clearing the CMOS, though I can't access the battery to remove it, since the wire is wedged under the ethernet port and is inaccessible. I had flashed to the latest Bios when I got the motherboard about a year ago, and I have had it running the ram at XMP stably at 3600. I also slightly undervolted the 3080.
The behavior when I try to use the computer is as follows:

The behavior when I try to use the computer is as follows:
- LEDs all turn on normally when I plug in
- When I press the power button, fans turn on as normal. The first couple times I turned it on after returning to town, it made a weird creaky noise, but I think that might be the radiator fluid spinning up after several days off.
- Corsair SF750 fan spins briefly and then shuts off. This is normal behavior since the power supply does not spin up its fan unless under heavy load
- No display signal is detected by any monitor
- When I try to turn off the computer by holding down the power switch, it does not turn off (indicating a potential motherboard issue?). The only way to turn it off is via unplugging / turning off the power supply switch.
