Motherboard Resets 2-3 times before powering on normally

I have just finished building my PC and after a PC has been turned off from the power socket (Cold boot) it resets the BIOS a few times with PSU making a switching sound... after a few times it boots normally. It happens even if I have everything set on Auto in BIOS with no XMP (So the bare minimum DDR4 Speed). It does this even with the default settings in BIOS.

I was thinking probably it's a memory & BIOS thing, but I have the most recent BIOS version... also it of course might be a PSU, but I don't think it is.

Anytime power is cut off from the board, the bios goes through a series of memory training cycles/reboots.

This is completely normal behavior.

So, it's not going to damage the PC components because each PC boot is causing all PC components to turn on and off a few extra times...
