Pc wont post. Red cpu light.

Pc wont post. Red cpu light. I feel like ive tried everything. It all started when i put an external power button on my pc. The next day when i went to turn it on, no post and red cpu light. I got a new motherboard and cpu, tried different ram, different ram placement, different graphics card placement, different hard drives, removing my m.2 ssd, etc. And nothing worked. Now the computer takes a second to turn on after pressing the power button and it is still the same symptoms. Any help is appreciated

so you got a momentary switch and wired it on to the PWR jumpers on the motherboard?
