Make and model computer?

Have you opened the case (power off and unplug first) to look for loose connections and seatings?

Ensure that all connections and seating (RAM, jumpers, PCIe cards, etc.) are fully and firmly in place. Likewise for cables.

May look okay but a gentle push may discover that there is some looseness.

I made the computer myself. I have also opened the case up and disconnected and reconnected all the possible wires (PSU, Button to MOBO cord) still no post just the power button on continuously

Any power on beeps? Any motherboard LED's?

Are you able to access BIOS/UEFI? Safe Mode?

Double check the power connections from wall outlet inward.

Overall I would suspect the PSU has failed.

No beeps or lights on the MOBO. I can’t get the computer to get do launch. I don’t think it is a problem with the Power Supply because the the power button has led and the keyboard and mouse also RGB elements and they are still working.

PSU's provide different voltages to the motherboard and associated components.

So there can be "power" but some components will not work.

Good explanation about what all is involved.

And if you have a multimeter and know how to use it then you can test your PSU.

Or, if not, find a knowledgeable family member or friend to help.
