Power on problem

Hello, recently i built my first PC and when I try to power it on it turns on for less than a second and switches off, after about five seconds it powers on again, POSTs and boots windows, I've noticed that it only does this when the computer's mains power plug has been turned off (for example if I where to restart my computer right now, it would turn on normally. however if i turn off the wall socket then the problem would reappear)

I asked my friend if his new home-built PC does this and he said his starts normally.

this is the configuration i have set up between the wall and PC

wall socket>surge protector>psu

SPECS:

ASUS SABERTOOTH z77
EVGA GTX670 FTW
CORSAIR HX750 80+ GOLD
INTEL I5 3570K

Is this all normal? or is it a problem that could potentially harm my PC? if so how can I fix this?

Thank you for your time.
