Intel Motherboards : J3455M powering on-off-on before booting

1. I power it on after the power has been completely cut off from the psu

2. I make a change in the BIOS and save

3. I force the PC to shutdown by holding the power button

This wouldn't have been much of an issue if the hard disks did not power on and off as well. But I'm sure that this powering on and off is not good for them because the power goes off right after they start spinning.

Does anyone else have the same problem with J3455M? I have noticed another post about a different motherboard but not this one. Is this normal or is my motherboard defective?

I have already sent two emails to Asrock tech support and I'm still waiting for a reply.
