hi
i faced this issue after cleaning my pc after putting cpu back in place.
The pc didn't turn on but after a while it did and worked fine
After shutting it down my PC's internals were still on, I checked power plan/bios and i didn't find any change from before.

After shutdown i can't start my PC with power button,
psu/fans/hdd stay on while monitor is off.

sorry if it was bad and unorganized English isn't my first language
please help me if you know the solution
