Turning on/shutting down issue

Hello,
I cannot turn on my PC at all until I unplug something, like when I try to turn it on it doesn't work, I unplug the Display port then I turn it on and after it turns on I replug it.
I also have problems with shutting down, I sit the pc down from Windows and it shows me the "shutting down" thing and then it suddenly shuts off like it's been unplugged from the wall.
I have my AC, phone, monitor, router and PC.
And I'm using some extensions and adapters because the wall plug is pretty far.
By the way I replaced my Mobo CPU, ram and GPU because the previous build had other problems.

PC Build Steps

Ok just because I like steps i am going to create some steps. Please give me the stamp of approval/disapproval

• Install system in case
  • Remember to connect SSD and optical to same SATA ports on motherboard
• Turn on PC
• setup HDD
• run blend test in prime95 for 30-60 min
  • run realtemp at the same time

• While in Prime95 test
  • if CPU goes above 70c in RealTemp, I have a leaky CPU
  • if my system locks up or blue screens, there is an instability in the system somewhere
  • if my system does not lock up or blue screen, my CPU is not damaged and I am in the clear!

What do you guys think??
