PC turns on instantly after power supply is on and I get no display. What's causing this?
I've just built a PC with RX 580 2048SP, Ryzen 5 5500, Machinist B450, Orico 1TB SATA M.2, Pinnacle 1×16GB 3200MHz RAM and a 600W PSU. I have this issue where the PC turns on instantly after the power supply switch is on (without pressing the power button) and I get no display. Pressing the power or reset button does nothing. I tested the GPU and RAM in another PC and they worked fine. And the motherboard says it supports Ryzen 5 5500 and SATA M.2 drives. btw Windows hasn't been installed yet. I'm still trying to install it, but I'm not getting any display. What's causing this issue and how to fix it? I removed all USB devices and all front panel connectors, but still having this issue.
