Question Asus Tuf b450-Pro: after enabling DOCP, the screen, keyboard and mouse stopped working ?

[Eman12]

The other day I turned on DOCP from disabled to profile#1 and then restarted but the monitor, the mouse and keyboard didn't turn on & the GPU fan kept buzzing loudly.
I tried to clear CMOS with a screwdriver, touch two "CLR cmos" pins for 10s and remove cmos battery 5p but still not working ?

have you a second GPU to try? It's very odd that it should fail at the same time as you tried DOCP, but strange things do happen.

What are the entire system specs? in addition to motherboard, GPU, cpu, memory and PSU, brand and model.

Does that board have any Q-LED's to light for indicating where it fails in POST? if not do you have a speaker you can hook up?
