I’ve never seen a cpu air cooler that oriented with the airflow vertically. Is that the proper way to install? I don’t know shit about shit, but could it be a cpu hearing up and shutting everything down for safety?

I’m surprised there’s no error leds or indicators that blink to communicate the error code.

You can mount coolers that way it's fine. But the issue couple be related to un even mounting pressure. However I wouldn't start there.
 1. Unplug all things usb. And check all power to motherboard. Try booting

2. Clear cmos. try booting

3. If have sata storage disconnect power to or unplug from motherboard. Try booting

4. Try 1 stick of ram and in different slots. Try ....

5. Remount cpu cooler checking for even mounting pressure. Try booting 

6. Pull everything out of the case . Place on wood or cardboard connect power. Try booting.

7. Try different psu

8. Try different cpu

9. Try different motherboard
